### Human: Kinetix 6000 Error E90 on 2094 IAM module. I'm currently having an issue with Kinetix 6000 Servo displaying an Error E90. Can anyone help elaborate on what causes this error and why the Precharge resistor would be overheated. System has run like this for years with no issues so i do not believe there is a sizing issue. ### Assistant: Hi Joshua, You are Welcome. Fault E90 is Precharge Timeout Fault, it occur when precharge resistor power exceeds the resistor rating. It is advised to wait for resistor to cool. Fault E90 is based on an algorithm to prevent the IAM's pre-charge resistor from overheating. Parameter 181 (viewable with Drive Explorer) is a warning bit that is set prior to the fault and Parameter 618 indicates the amount of time remaining before the warning bit will clear. If power is cycled while 181 is set, then the E90 fault will occur. See the release notes 2094-RN005A-EN-P_Jun05 for more information. E90 will flash on the seven segment Kinetix 6000 display and the IAM's contactor enable relay (-CONT EN, +CONT EN) will open to remove 3-phase power if it has been wired in per the installation instructions. Recovery from the E90 fault is accomplished using a MASR or MAFR, after 30-60 seconds to allow the resistor to cool and the IAM's contactor enable relay (-CONT EN, +CONT EN) will close. If the reset is attempted too soon the E90 fault will immediately reappear. Hope this helps. \n

### Human: Powerflex 753 losing Max Fwd Speed after power Reset We are having a powerflex 753 connected to the PLC over ethernet. When we try to change the Max Fwd Speed (P520) from 50Hz(old ) to 70Hz(new) , we found that it takes the setting and motor runs a bit faster , but when we power recycle we see that the Max Fwd speed goes back to 50Hz . The parameter P300 is set to Hz only and not RPM We tried for other parameters and they are getting saved even after restart Any suggestions ?? ### Assistant: Hi Rahul, Disconnect the drive from the Ethernet communication and change the parameter P520 using keypad. Recycle the power and check, If Drive retain the value, then check the datalinks. If Drive lost the updated value of parameter and return to default value, flash the drive on latest firmware.. \n


### Human: 10 HP Bucket Modification Question Hello, Was wanting to check and see what y'all thought about a potential modification to the bucket I have attached. We are looking to add another 10 HP motor to one of our tanks, and we are looking to have one motor run for a period of time, then turn off, and then start the other motor for a period of time. My management was wanting to see about the possibilities of using only one bucket to accomplish this. My thought was to add a couple of contactors with a mechanical interlock after the overloads on the power side of the circuit, and use my PLC to control what contactor is currently pulled in. Was wanting to see if there were any other ideas though, and if there were any concerns with my idea. Thanks, ### Assistant: Possible but IDK if I'd do it. The bucket wiring from the factory is UL and generally you don't want to modify it... especially the power circuit. Where are you going to put the two contactors? In a separate bucket, or remote.? Is this going to be confusing to troubleshoot or lockout/tagout? One motor is running while the other is not... it's Out of Service, OOS. How do you work on the OOS motor? e.g. Lockout/tagout. Maybe you could just order a bucket that was designed for this application. Disconnect, short circuit protection, one E300 OL ahead of two mechanically interlocked contactors... all in the same bucket... not any larger than a FVR bucket. Or, just use two bucket. \n


### Human: Motion Control with External Encoder I have a PowerFlex 527 on a motor that drives a turret. There is no encoder on this motor. I have an 843ES encoder mounted on the turret. I'm running a 1756-L82ES processor. I'd like to use motion commands to position the turret. I do not see how to tie the external encoder into the motion axis. It only gives me motor encoder as an option. Any suggestions? ### Assistant: No, the 527 does not support the encoder connected to the load. However, you can use application code to utilize this encoder by bring it in on an HSC card and tying it to a virtual axis with MAM which will calculate the velocity... use the velocity to trim the VFD setpoint.

### Human: Kinetix 5700 | Digital input | Registration | Scan time | Capture time | Cycle time Hi all, I got the request from a customer regarding subject. What is the scan time or Capture time or cycle time of Registration(digital input) ? I found below information on manual but, there is not specified 'scan time'. ### Assistant: Hello Kang1 I think that the registration input work on Interruption and Time stamping, so scan time (if we can call it like that) will be much below the registration repeatability. Why do you need this detail, since it we already provide all the relevant information for a proper calculation? What is your application needs ? On top of that you should also consider that the sensor reaction time and scan time are most of the time the bottleneck of a registration system. regards \n


### Human: Max. Motor cable length with/without AC line Filter for Kinetix 5700 Hi everyone, I am using MPM-B1653F-MJ7AAA ( quantity - 1 ) connected with kinetix 5700 2198-S086-ERS3 single axis inverter (quantity - 1). VPL-B115E-PK14AS ( quantity - 6 ) connected with kinetix 5700 2198-D020-ERS3 dual axis inverter (quantity - 3). Single DC bus supply ( 2198- P141) which is 480V AC input So, this DC bus supply is connected with the above 4 invertes. And I am using Single turn Drive to motor feedback cable (so i found that the max cable length is up to 90 m). I am using AC input power type WYE grounded. In the 2198-UM002 manual, I have read that, The sum of the inverter motor-power cable length for all invertes on the same DC bus-Sharing group must not exceed, -1200m when used with 2198-DBRxx-F line filters. -400m when used with 2198-DBxx-F line filters. Since i am using 7 motors, it would be 7*90 = 630m. My questions are: 1. So, in my case is it mandatory to use AC line Filter ? 2. If it is not mandatory will each of my 7 motors still support 90m each with out using the AC line filter. 3. what would be the max. combined length of motor power cable if I am not using AC line Filter? WIll it be 90m each or something else? 4. And how come the combined cable length is 1200m when used with 2198-DRxx-F line filters ? Is it like ( 13 motors * 90m =1170 [approx 1200]) ? ### Assistant: Hello Chalagulla Please review this manual Drives in Common Bus Configurations with Kinetix 5700 Bus Supplies but you have found all our recommendation already i guess. Yes , we strongly recommended to use a Filter that match your application. an AC line filter have an important role to protect you installation and guaranty the good working condition do you have a specific application that request a remove of the filters ? details please best regards \n


### Human: Powerflex 755 - Vector control - How to set up two motors connected in parallel Hello How can I correctly set-up a powerflex 755 drive that controls two motors connected in parallel using a FOC/Vector control?

### Human: Question on PF40 and PF70 Accel2 and Decel2 Hello everyone, I have a question about the PF70's Accel 2 and Decel 2 parameter. From what I've found in the User Manual. The only way to use decel 2 on a PF70 is to have a Digital Input parameter (361 to 366) set to value 20 (for Accel 2 & Decel 2) or 22 ( for Decel 2 only). I could also be using the DPI but in this case that's not an option. We want to use the Digital Inputs. In comparison, when using the PF40 with different preset speeds. Preset speed 0, 1, 4 and 5 will use accel 1 and decel 1. While preset speeds 2, 3, 6 and 7 will use accel 2 and decel 2. Does the PF70 work the same way or is my initial thought of having to use another Dig. In correct? ### Assistant: Digital input can only be assigned to one function at a time so you need a digital input to select value 20 (for Accel 2 & Decel 2) or 22 ( for Decel 2 only). The Speed selection would be a different digital input \n

### Human: Powerflex 525 Test Bench Setup on single phase I am trying to make a test bench setup where I can control a 3phase 1/3HP motor from a single phase input. I currently have a 120VAC to 240V step up transformer that I have landed 240V single phase on L1/L2 of my 2HP PF525 model 25B0D4P0N114. The HIM powers on but I have a F004 fault for low voltage that I cannot clear. I read 353VDC bus voltage when connected to the drive in CCW. I can connect to the drive in CCW but cannot modify any parameters. I read the tech note where Powerflex 25B series drives can take a single phase input and control a three phase drive de-rated but I have not been successful. Has anyone else been successful utilizing a single phase input? ### Assistant: That catalog number is 480V input and you are only providing 240V. Yes, you can bring in 1-ph and output derated 3-ph , but the input voltage must be correct. \n


### Human: Powerflex 525 and 753 two sets of variable speeds Hi, this is my first post on here so please be gentle! I have a machine that we perform size changes on and the drives (powerflex 525 and 753) speeds are controlled by linear potentiometer, currently at a size change we change the minimum and maximum frequency settings to give us the speed range required. I would like to add a two position switch to change the frequency's for two different sizes. With the 753 am I correct at thinking I can use parameters 547, 548, 552 and 553 to allow this? I cannot see similar parameters on the 525 so could I use the jog facility to achieve this by having one range of frequency's when in run and a different range in jog and would they both work on the 0-10v potentiometer? Or is there an easier/better way to achieve this? Thanks in advance for any advice. ### Assistant: Hello, you are very welcome. There are some technical notes available from the Rockwell Knowledgebase that could help with the task ahead. For example for the PowerFlex 753 drive PowerFlex 753: Configuring 2 preset speeds using 1 Digital input can be useful. For the PowerFlex 525 drive PowerFlex 520 series drive: Using Different Preset Speed Values with 2 Wire Control can also help. Both papers above assume the frequency to be switching between fixed values (preset frequencies) stored on parameters on the drive. This could be an easy way to do it. \n


### Human: How to download parameters of drives via device net? I have a 1769-L32E controller attached with a devicenet module (1769-SDN) which consist of 7 nos of POWERFLEX40P Drive .

### Human: Kinetix 5100 to DeltaV (PK Controller) explicit messaging Hi all, We are working with a Kinetix 5100 drive which we want to connect to a DeltaV system using a PK controller through Ethernet IP, the drive will be used to control the speed of a pump for a bag and bottle filler, previously in a past project it was used the Kinetix 300 but since it'll be discontinued, we were told to use Kinetix 5100 instead, Kinetix 5100 manual indicates that we can use same explicit class 3 messaging like Kinetix 300 to communicate with DeltaV but the Input and Output assembly data shown in the manual says that is intended to use only with IO mode (Class 1 Ethernet/IP connection). Does anyone know how or where to find the Input and Output assembly data when using Class 3 explicit messaging? Any help would be appreciated. Thanks in advance Edgar V ### Assistant: Hello, you can perform Class 3 Messaging to an external device only. The I/O assemblies are only available using a Logix based controller as you mention. You can use the example MicroLogix 1400 or Micro800 Class 3 messaging examples on the SampleCode Library (or available from your local Rockwell Automation Tech Specialist or distributor). These examples show how you can get some meaningful (but not as rich as the I/O assemblies) information passed between the controller and drive. Hope that helps. \n

### Human: Constant Force (Torque) Application I have a customer who has specified Kinetix Servos with an application that requires a force that is within 10% accurate and must hold that torque for a required amount of time. At any point, the system may need to adjust that torque. The torque feedback sensors will be TBD load cells. I'm working to convince this customer to utilize air cylinders with electronically adjustable regulators. I've done the math and am certain I can hit the requirement with air cylinders. Have any of you seen a Kinetix system utilized to create an accurate holding torque? I have never really used a servo system in this topology. Thanks! Seth ### Assistant: Fuller, I'm not a motion guy so there could be a better and newer solution.... About 10 years ago, I consulted on a Servo torque application that had load cell to measure force via 1734 Point IO. We could set a torque limit on the servo and observe the force on the load cell. Although the torque (current) per pound force would vary (due to motor heat, etc.) we had a good starting point to close in on the desired holding torque. The logic used an initial torque setting that would be slightly below the desired torque. Then it would measure the force on the load cell and increment the torque limit,,, repeat till it approached the desired force. The logic was a periodic task, if the force was below the target, then add to the torque limit... repeat as necessary. You could speed it up by making the task faster, or making the (torque) step size larger. The servo allowed us to quickly move into position where the part would contact the load cell using a low initial torque and the ramp up the to the final torque using the integrator logic. \n

### Human: Serial Communications in LabVIEW are giving incorrect data compared to Ultraware Hey all, I am running into an issue with data that I see in Ultraware 3000 compared to what LabVIEW is reading when requesting the same information from the servo via serial communications. my LabVIEW code is basically taking the host commands for serial communication for Ultraware 3000 and sending commands to the servo. After I initialize communication on the serial port, I then query the servo for its interpolation (x000ED0 w/ checksum) and lines/rev (x000370 w/ checksum). The lines/rev returns correct but the interpolation is returning a value of 4 while Ultraware says the interpolation is set to 8. The reason I am querying these values is because I am trying to determine the total counts/rev for the servo's output shaft so I can set the servo to a desired output shaft speed or position without needing to worry about manually knowing what these values are for the servos I use. As far as I can tell, all other commands being sent to the servo work as expected except when I query the interpolation. Any help is greatly appreciated. Matt ### Assistant: Matt, I'm sure you've seen the serial communications manual. It seems you are reading data file dd =0x00 which is decode to 4 while UltraWare indicates 8 lines per revolution. You could use a RS232 tap to monitor the UltraWare traffic. But I suspect it is the same as your LabVIEW and either UltraWare is displaying it wrong or the documentations is wrong. Either way, I'd just verify your application is interpreting it correctly (even is the documentation or Ultraware is wrong). \n

### Human: Predictive maintenance for MPL, MPM servomotors Good afternoon, I want to make a predictive maintenance plan for servomotors. Anticipate before failures occur, since I have many servomotors, both with K6500 and K6000 drives, how can I do it? What parameters would I have to take into account, some software or formats to be able to do this monitoring of each servomotor I will thank you. ### Assistant: Hello Gaam this is a very interesting topic. The fact that you have already installed motors since a certain amount of time, it makes difficult to estimate the time that those motors are already in use... so this will not allow to estimate the L10 time. On top of that many external factors will affect the motor lifetime, like radial effort, axial effort, cycle type, environmental pollution, motor capacity, transmission and load type.... etc this is why I will suggest you, to look at the torque (or current) , the position error, motor temp, drive temp.... those type of information's start to deviate and increase from the normal recorded state, they will give you a sign of something going wrong. on newer equipment we have features that helps a lot , like the VTS (Virtual Torque Sensor) , and some AOI's . But all will depend on the Logix version you have... a bit more details on your installation and type of equipment will help us to drive you toward the optimal solution. for very sensitive equipment we also have a true condition monitoring solution, but this is a different level of integration and investment regards \n

### Human: Virtual Torque Sensor Hello Good Morning, I was working on predictive maintenance for Kinetix 5700 servo drives using the add on feature virtual torque sensor for jams or mechanical system issues including gear tooth fracture or breakage in gearboxes, bearing damages, damaged coupling, damaged balls crews, and broken blades or wore blades in rotary knifes etc. There was an AOI developed by Rockwell to detect any disturbances in the profile. I am using the Torque estimate for the detection as said by the document. My question is I am doing a test on the Kinetix 5700 on a motion drive using a single axis & I configured for velocity loop. There is not much information about the use of AOI. For example, My test procedure is as follows. At First I wanted to record or save the good profile & then stop it then loosen the couplings so that the AOI will detect the disturbance based on the first profile. But I was not able to detect the disturbance. I am looking for some information on the AOI I am attaching the AOI_LoadConditionMonitoring_v2 pdf for the reference of the AOI. There is not much information on the knowledge base as well regarding the test procedure or about the AOI Thank you ### Assistant: Sai, Never seen this AOI before but the picture from the pdf graphical tells me what I need to know, During the yellow highlighted period, the monitored value is above min. and below max.. thus normal. At the end of the yellow highlight period, the monitored value dips below the min. value and this starts a timer If the monitor value remains low and the timer completes, it sets a Boolean to indicate a disturbance is detected. The trick is to have a measured value that can reliably indicate there is a problem. I'm guessing a loose connection might show up as a period of no torque, or high positioning error, or maybe non-linear response. but it might be too short to see or otherwise masked by the closed-loop algorithm. \n

### Human: Using MAJ instruction when a MAG is already active Hi everyone, I'm actually trying to torubleshoot a Tension control system created for an OEM and the way it actually works is gearing the axis with a virtual master and then after passing a defined speed they are enabling the tension control and beginning using MAJ instruction with a speed value calculated using a PIDE instruction using like input the tension provided by a load cell and a defined tension Setpoint I know that we can superimpose a MAJ instruction in an active MAG but I need to know how it is going to work?. What I'm actually seeing is the axis running at aprox 5000 degrees/Sec (close to the Virtual Master speed * gear ratio) and values in the speed of the MAJ instruction oscillating between -15 and 15 (completely far from the actual velocity value around 5000 degrees/sec). How this MAJ instruction is actually working?. Thanks in advance for all your comments adn if you think more info or clarification is required please let me know. ### Assistant: Hello Munoz this is a common way of doing tension control system, the feedback may vary a lot and features as well. but most of the time it's the use of the move compensation or/and outer loop control equation, that could be more or less complex depending on the application requirement in term of dynamic and accuracy of the control. Some use directly the gearing factor to track the setpoint, of some like in your case use the Superimposed movement. So in your case the JOG (MAJ) is used as a superimposed movement on top of the actual movement (MAG). This is possible thanks to the great Logix/Kinetix motion control system implementation. Internally the movement are all incremental and they can be summed before being sent to the output command for the Servo Drive this the magic part. see bellow diagram So if you have a MAG running on your axis you are still able to apply another movement like a jog, and the sum of the 2 movements are sent to the axis drive. This is possible also because of the incremental internal treatment. So this is very simple in fact... nothing special a, a MAJ can be superimposed to any actual motion movement running on the actual axis. the end result will be the sum of those movement. so your axis run a 5000 deg/sec and each time your algorithm requests it, a superimposed Jog of + or - 15 deg/s will be applied. Depending on the code this could be executed once or multiple time in the row (that will impact the dynamic and the compensation capability). But that needs to be controlled in a nice way to avoid any overshoot or pumping effect that can conduct to uncontrolled motion, since you are using an outer loop control system. Does that help to understand. so, your velocity command will vary with increments of 15deg/s (pos or Neg) to make the load cell matching your load setpoint. I hope that helps regards \n

### Human: Protection for external brake resistor Hi guys! We have problems with 755 drive's brake resistor: one terminal was grounded by loose metal clamp, resulting in IGBT blowup... My question is ¿What is the apropiate protection to drive? I don't find rockwell's recomendation to this. ### Assistant: For externally mounted braking resistors, the recommendation is to protect the drive from resistor temperature rise. This is done typically by a normally closed contact from an internal thermostat in the resistor. This signal is often used to open a contactor upstream the drive and remove the supply. However, the protection above will not be able to detect the failure of the internal breaking IGBT on a PowerFlex 755 drive. That type of IGBT failure may require fast DC bus branch short circuit protection. A possible way maybe the use of an external breaking chopper (or DBU - Dynamic Breaking Unit) and use an appropriate fast fuse to open the DC bus circuit and protect the IGBT inside the DBU. More information and general guidance about this is discussed on https://literature.rockwellautomation.com/idc/groups/literature/documents/um/akdbu-um001_-en-p.pdf Please, also note that for High Horse Power PowerFlex 755 (frame 8 and above) the only way to use an external braking resistor is with an additional breaking chopper (since those frames do not have the internal breaking IGBT). For frames 1 to 5, the breaking IGBT comes a standard and from frames 6 and 7 is optional. Thanks. \n


### Human: Using MRP instruction over a Master axis followed for slave using MAG with Master Reference command Hi everyone, Right now there is a system with a Virtual Master Axis defined in meters, it is moved using MAJ. This master is guiding a winder defined in meters using a MAG with a fix gear value and the winder is guiding a spindle defined in degrees moved by MAG with Master reference Command and ratio variating according to the diameter of accumulated material in the spindle. This MAG is continuosly updated using a XIO condition of the MAG EN bit just before the MAG instruction. What I'm trying to do is use a MRP instruction to update the winder position to 0 when a splice has ocurred and it's starting the wind in a new shaft. I want to know if doing this I can cause any instruction fault on the current MAG with Master reference command or what other consideration should I have into account?. Thanks in advance ### Assistant: Hello Nelson Can I rephase what you are doing to make sure that I got it correct? You have a Winder that is geared to a virtual Master with a fixed ration. On this winder you have geared a spindel with a variable ration. And you would like to do a MRP on the Winder at a specific event. If the above is correct, this is possible without generating any MAG instruction fault on the Winder or Spindel. All axis stays geared with the same ration. you can run the MRP absolute or relative mode on the Actual or command position. That will only affect the Position counter of winder not his motion. What could be affected is if some equipment's are dependent of the position of the Winder. but apparently in you case it is not. I hope that help. regards \n


### Human: 6 Axis Robot Control Hi, I am hoping that someone can point me in the right direction in terms of hardware selection. What would be the minimal family range that can communicate to a 6 axis robot, Compact Logix, Compact GuardLogix, Control Logix or Control GuardLogix? ### Assistant: Welcome to Engage! Strictly looking at the number of axes to be controlled, I would say a CompactLogix Controller can do the job. You can start to read about available features in the CompactLogix Selection Guide There are a number of things to discuss beyond that, so it would be better for you to get in touch with a local Rockwell Automation representative. fuzzy logic Please don't forget to LIKE and highlight the decisive answer: REPLY > Make Best Answer \n


### Human: Upload Parameter from Kinetix 350 Hello every body. We have 5 kinetix 350 servo drive which have connected to 1769-L33ERM CPU in our machine . I want to back up program from PLC and Servo drive. If I upload program of PLC , are there parameters of servo drives in program of PLC? ### Assistant: Hello Akbar Kinetix 350 is a CIP motion drive, so all the parameters are stored in the PLC code and loaded fat startup to the drive. So yes if you save the application code you will save all. Also if you replace a drive, you just have to set the IP adress of the drive and at startup (power on) all the parameters will be loaded automatically from the Controller (PLC) via ethernet IP cip Motion to the drive. Regards \n


### Human: Loadcell feedback to a Kinetix 5700 drive Hello all, Keeping it simple, I am running a servo to a force. I have a loadcell to an Analog input card that feeds MCD instruction to control a MAJ velocity. This works, but I am thinking that a could wire the loadcell directly to the secondary feedback of the K5700 and just use a MAM with the loadcell target? Dose anyone do this. This there any information to help me. My (current) loadcell provides -10/+10 3 wire. ### Assistant: Morley, Here is a discussion about force and torque. https://engage.rockwellautomation.com/discussion/constant-force-torque-application \n


### Human: Powerflex 755 with PM motor - Effects if moise in encoder feedback readings Hi everyone For a PowerFlex 755 with PM motor with incremental encoder. If we have noise and/or encoder inaccuracies that affect encoder feedback over time will this jeopardize motor commutation over time? On the first start after a power cycle, we do the PM Offset test and the relationship between that angle and encoder feedback is good, so we have proper motor commutation. But eventually if the encoder feedback is not accurate for any reason over time, will we loose that relationship between the commutation angle and the encoder feedback? Will we lose proper commutation of the motor over time? Can this cause Overvoltage faults? What other effects cuald affect having this issue with the feedback? Thanks in advance ### Assistant: Hi, Check your encoder cabling route, it must be far away enough from AC power cable. Check with OSC on your encoder square wave output , to ensure encoder can send correct output signal. Terence \n


### Human: Changing encoder in a HPK-B1613C-SA42AA I am in the process of changing the SICK SFS60-HPZT4S01 encoder inside our HPK-B1613C-SA42AA servo motor. The encoder not only tells the drive how fast the motor is spinning, but it also tells the drive the specs of the motor. SICK says they don't preprogram the encoders, and I would need to get the EPROM from Allen Bradley in order to download it to the new encoder. My question is, is it possible to get the EPROM from them? ### Assistant: EDIT: linkified for convenience -FL Hi Jonathan, I'm not sure if this can answer your question but I'm seeing that Rockwell sells the complete Replecement kit for HPK series motors and provides the installation instructions. https://literature.rockwellautomation.com/idc/groups/literature/documents/in/hpk-in002_-en-p.pdf \n


### Human: PM Offset test in load sharing configuration between Permanent Magnet motors Hi everyone. We have a load sharing configuration betweeen 2 permanent magnet motros coupled to the same shaft and with only one encoder signal for both. My question is how can prevent or configure sequentially the drives to perform the Auto PM Offset test after a power cycle?. So it's clear that the drives needs to perfomr this test after every power cycle but how can we prevent the drives doing the test at the same time? Thanks in advance ### Assistant: Hello Nelson. could you give more details about the equipment that you are using. provide the Motor type and encoder type, the drive and controller. this way we can identify. If you use a complete system with Rockwell Automation equipment, you should not have to run the offset test. if some HW are not Rockell them it's a different story... and we need details. regards \n

Thanks in advance ### Assistant: Hi, From the help tab in studio 5000 The Faults & Alarms page displays the current status of faults and alarms log structures currently in the controller for this axis. The display is read-only except for the ability to clear logs independently. don't think it is possible I am afraid. \n

### Human: STO during deceleration EDIT: moved to Drives and Motion community -FL I have some servos on K5700 drives. The STO get broke with a light curtain block. This works fine during the move, the servo stops and restarts with an opto, but if the light curtain gets blocked during deceleration the drive keeps going and actually overshoots the target. Has anyone else seen this? There is no brake, but the servo is under load and should want to stop. ### Assistant: Hello Morley, couple of questions for you: What Kinetix 5700 are you using ERS3 or ERS4 ? Are you using a wired safety signal to the drive or a CIP Safety over EtherneIP ? When you operate an STO on a Servo drive you stop the motor control. So if you request a safety stop action that directly does an STO on the drive , the motor will coast without any control whatever the movement you were doing. This is called a stop category 0. So this is normal that you can overshoot a target since no more control is applied to the motor. With the Mechanical and load inertia the motor can rotate freely for a certain time if you don't have a safety brake. Now you can deploy a different safe stop category. Safe Stop category 1 , called also SS1 . Now the SS1 will give you time to decelerate correctly your axis and stop if before STO occurs. The way of deploying this feature will depend of the answers you will provide on the previous questions. you can also look at this manual : Kinetix 5700 Safe Monitor Functions Safety Reference Manual (rockwellautomation.com) (Link updated) regards \n


### Human: Powerflex 755 Speed Trim Follower Hi everyone, actually I have the following drive configuration: There are 2 Permanent Magnet motors driving the anvil roll – one on the drive side and one on the non-drive side. The motors are sized at 76.28 kW each (152.56 kW combined). Each anvil motor is controlled by a 302 Amp PowerFlex755 drive – three phase 480VAC fed. Each drive has a 5.3 ohm 22kW dynamic braking resistor connected to it. Only one motor has an encoder on it – the drive side motor (master). The feedback from this encoder goes to the drive panel on the 3rd floor and is split to 2 signal converters. The signal converters output are wired to each drive's Dual Encoder module. The drive side roll runs in Speed Regulation mode with a speed reference passed from the machine Webformer section. The non-drive side roll runs in Torque Regulation with Torque Reference Setpoint set by the drive side Limited Torque Reference feedback. I would like to know the list of parameters to change and the required wiring (if required) to change this configuration to Speed Trim Follower because what we are seeing is that normally one of the drives is managing the major part of the torque so the load sharing system is not working properly. I need to know in detail about the parameters for passing the current Master torque to slave and the required for the slave to compare this value with its current torque and use the error to apply the speed trim. I hope this explanation is clear and thanks in advantage. ### Assistant: EDIT: removed external formatting -FL Hello, there is some conceptual guidance on how to apply a Speed Trim Follower scheme with AC drives via the following document: https://literature.rockwellautomation.com/idc/groups/literature/documents/wp/drives-wp001_-en-p.pdf This other technote includes a document that goes a bit further highlighting the challenges ahead based on the block diagram of a PowerFlex 700VC drive. There is mention of the Process PI Trim to be required to accomplish this scheme. https://rockwellautomation.custhelp.com/app/answers/answer_view/a_id/516124 I think the way forward would be to understand how this is done on the PF700VC and try to extrapolate or correlate those key block path diagrams from the PF700VC to the ones in the PowerFlex 755. The Reference Manual for the PF755 includes some detailed information at block diagram level as well. https://literature.rockwellautomation.com/idc/groups/literature/documents/rm/750-rm002_-en-p.pdf The other challenge, once the key parameters are identified will be to pass that information from the master drive to the follower(s), possibly by mapping those key parameters to analogue signals and wiring those accordingly. I am leaving an open door here to see if there is anyone on this audience that may have used this concept within a real drive system application and would like to add some advice on what could be a challenging, but very interesting application. \n


### Human: Powerflex 753 speed ramping with Digital Input Hi I am having a PF753 drive with Digital I/O control . Now we need to set the drive to work in following way . When start command is given the drive will run at a minimum speed . When a digital input from selector switch is given then the speed should be ramp up by certain percentage . say for e.g if the start speed is 10hz , when the input is given then it will run at 11hz , and when second time the input comes to drive the drive should run at 12hz , in this way the speed needs to ramp up every time input comes. Is this possible ?? ### Assistant: P177 - DI MOP Inc Digital Input Motor Operated Potentiometer Increment see p73 and p395 https://literature.rockwellautomation.com/idc/groups/literature/documents/pm/750-pm001_-en-p.pdf \n

### Human: Kinetix5100 Micro LC50 Hi Everyone 1st time posting here. I have a Kineti5100, MicroLC50 and downloaded software provided by Rockwell, example code. Dynamic Position Move, using the C_RA_K5100_Index_CmdSts_V2.2 Everything works just fine except for one thing. After issuing a STO function and then resetting the safety. The C_RA_K5100_Index_CmdSts_V2.2 will not reset the STO fault. It will reset all other faults but not this one. I have used the same drive with Compact Logix and that UDFB will clear the STO. Any guidance on resolving this would be appreciated. Thanks, Dennis ### Assistant: Hello, I have the same problem. I found in the release notes of firmware 1.2, that this fail was fixed in that version, I try updating but stopped working some parts of the PLC-K5100 communication. Try version 2, 3 and 4, same problem (no communicaction). My next step is to change PLC to micro 850 new generation, as it accepts class 1 ethernet ip with new instructions similar to CIP MOTION. I suggest trying version 2, if it works for you, please share. \n

### Human: PF525 Rating Table Object? Hi all, I'm reworking an AOI I wrote for the PowerFlex 525 and am diving into the DPI objects documented in 520com-um001_-en-e.pdf. One parameter I originally put to use to establish parameter ranges is D367 [Drive Type]. I made use of QA20724 to get rated horsepower, power, current, output voltage range, input voltage, and rated current, but the code to produce this is a little involved at 140 lines. I came across a reference to a Rating Table Object in the above manual and am hoping to see if Rockwell can divulge a little more info about it and whether it provides a more straightforward way of determining these parameter ranges. I'm perfectly happy sticking to D367 if there's instead some formulaic way of determining this information. Thanks! ### Assistant: JeremyM IDK about the Rating Table Object... but based upon the text provided, I can take a guess. In the case of PF750, I know there are over 1700 parameters in the Parameter Object. When looking at a 5 HP vs 500 HP, the parameter list is identical, however, the values (min, max, default) will be different. As it turns out, only 17 of the 1700 parameters are related to the power structure. So I think this table is for those 17 parameters to show the min, max, default that would change bases upon the power structure. For example: The output current (or anything related to current) is different (in terms of min, max, default) for a 5 HP vs 500 HP. \n

### Human: K5700 Drives Inverter Overtemp Fault We have a vertical load application with two axes sharing the load using the same K5700. For some reason when we move the axes up or down, we will intermittently get an Inverter Overtemperature FL Fault. So far, we haven't been able to nail down a root cause. It doesn't seem like the torque is causing this problem because we have tried with varying weights and torques, and it doesn't seem like velocity or acceleration are the main factors either because we have tried playing with the speeds. We trend the inverter temp and notice that this alarm occurs when the inverter temp hits 155.6 degrees C. Does anyone have any good ideas as to why this fault might be occurring in our application? ### Assistant: EDIT: added proper numbered list to questions -FL Hello Joe. Based on the little information's that you give us it is not easy to identify the issue you have. Some questions: is it a new installation that you are commissioning or something new on an old system? you said that the dynamic generates the over temp fault. what is the torque value before the fault occurs... are you close to 100% or above for how long , does the 2 motors shows approximately the same torque level (how did you manage the load sharing ? ) have you check that the break works correctly? stupid question (but I have seen it) check if the motors are not working against each other did you monitor the drive capacity tag? could you provide the Drive and motors ref , to see if they can match? do you have a current and position error trend ? Regards \n


### Human: Offset during dynamic gearing between virtual axes Hi Everyone , I would like to gear 2 virtual axes during either a run or before axis moves. In order to do that , I used following solutions but still got an offset when it was geared with ratio other than 1:1. 1) Using MRP Absolute to move slave axis to master's position then latch gearing. (1:1 it works but if the ratio is different , there is always big offset) 2) I calculated the actual position difference between master and slave and use this as failure to make relative move with MRP. ( I got 0.08 position difference at the end which might be ok but still not precise enough for me) ** Note : Offset happens when gearing ratio is different than 1:1. Is there any more reliable alternative to do it ? Thanks in advance. Sertac ### Assistant: Hello srtc the big advantage of virtual axis is that they are perfect (not position or velocity errors). So the issue that you have can not result of a bat tuning or mechanical setting...etc. It is certainly. a MAG setting or axes setting. could you give more details on this please ? to answer your 2 points: it is normal that if you do not have a 1:1 ration you will see a difference on your axes. are you using Ratio or Mastercount/slavecounts ? what ratio format have you selected ? are you using the clutch ? all those parameters will impact the gearing relation between your master and your slave. review the Logix 5000 Controllers Motion Instructions (rockwellautomation.com) manual (p112 to 124) to know more about those parameters. TIP: you can also use MAPC to do gearing, regards \n

### Human: Kinetix 5300 Communication I have two Kinetix 5300 drives in a new machine. Connecting to a 1769-L36ERM compactlogix processor version 33. I set the software up as we have in the past for the 350 drives. Both drives have configured IP addresses in the in the range of the processor. On startup the drives show up in my controller organizer as having no problems. They never come off the 00 state on the drives. If I unplug the Ethernet cable to the drives and re-insert. The drives go through their startup sequence and reach 04 state. I can start and run the drives without errors. I have replaced the 100 foot Ethernet cable out to the drives. I have replaced that cable also with a Cat 5e cable that checks out with our blackbox cable tester. I have moved the connection from the system Ethernet switch directly to a port on the processor. I have pulled the 24V supply to the drives until the system starts up, and applied power. The only thing that makes the drives come online is pulling the Ethernet cable and re-inserting. I have two powerflex 523's on the line that have no problem attaching at startup. What am I missing? ### Assistant: Don't have a good answer as to why you're seeing this phenomenon, but you could try programatically disabling the drives in the IO tree and then re-enabling them. It would do the same thing as unplugging the cable. It sounds like there is some sort of boot process foot race and the 5300s consistently fail the race. Programatically disabling / reenabling fixes the problem (though it doesn't solve it). The snippet below shows how to do this: You use value 4 to disable, value 0 to enable. I made constant tags to help others read the logic. Instance name is the name of the drive in the IO tree (not the axis name in the motion group). We use this sort of logic to allow the motion group to initialize on boot when a drive is missing / failed. All drives must be in place and communicating with the processor at time of PLC boot; if one is missing the motion group never initializes. The logic above allows an a drive to be programatically disabled which then permits the motion group to initialize and run. \n

### Human: K5300 current overlimit I have a 2198-C1020 wired 3 phase. I had some very slow motion out of control while testing. The setup is a mpl servo attached to a rack and pinion that carries the main machine back and forth. During startup, 3 or 4 times it hit the end of travel, at about 2in/s. On the last time I got an overcurrent limit fault and now I can't clear it. I tried all the reset, on/off commands, i tried cycling power, i tried a new motor. The machine didn't hit the end of travel so hard that it got stuck or did any damage, it just stopped. One mistake I made was forgetting to set the 3 phase power from single phase in Studio5000. Could this have permanently damaged the drive? It still powers on and goes through the full boot cycle to 04. Is there any saving this drive? ### Assistant: Hello pa_servo_guy, There is very limited information about this fault online. I would suggest calling into your local kinetix technical support team to assist with this and discuss best options. This link will bring you to the contact us page, fill in the required information and the correct phone number will become available. Contact us \n


### Human: PowerFlex 70EC I want to know what is the difference between 0-60 hertz on parameter 72? How is it going to behave at different increment? ### Assistant: Lee The Break Frequency is shown on p30 It is used to change the v/f line. \n


### Human: PowerFlex 70EC There is an issue at my work place. This is related to the pump we have and I want to know how to adjust the setting in the parameter for this issue. The pump is running off the pressure, and the pump modulates the speed to compensate with the pressure. We're running the pump in manual mode and the frequency on the VFD is 50 Hz. We also have a valve cranked 45 degree to supply the water to other area. Every time we're having a power outage it needs someone to manually reset the VFD and raise the frequency from 15 Hz to 50 Hz. If we're running the VFD in auto mode when there is a power outage the VFD will stay on at 15 Hz the whole time. I want to know how to adjust the 15 Hz to 50 Hz in auto mode and not having somebody to reset the drive manually from 15 Hz to 50 Hz. Any suggestion in this scenario? ### Assistant: Hi Lee, I replied in another your other thread. Thanks \n

You can add an offset to all your movements setting a MRP instruction (motion redefine position). The page 135 explains how to use MRP: Logix 5000 Controllers Motion Instructions. Reference Manual.

### Human: POWERFLEX 525 DRIVE STARTING ISSUE Hi, I'm using powerflex 525, I'm giving speed command drive and it is reflecting in drive Hz, but if I give start command it's still in ideal, Before it was running perfectly ### Assistant: Hello Suresh, There are three start sources P046, P048, P050 (start source 1, 2, 3) There are also there speed references P047, P049, P051 (Speed ref 1, 2, 3) If using ethernet IP (for example) as start source and speed reference the use P046 and P047 change these parameters to the correct value. It is important to make sure any of the other start source and speed ref cannot be set to the same value. Start source 3 and speed ref 3 are set to Ethernet IP by default and will need to be changed in this case. Hope this helps. \n


### Human: Kinetix 5700 to 5500 migration Hi I have a requirement to migrate kinetix 5700 drives onto the 5500 platform, initially it looks pretty straight forward but the 5700 drives have a configurable input setup as an external enable, unfortunately this enable input is not available on the 5500 drives. Both models of drives are mounted as a block but 5700 drives are dual modules and 5500 are single am i missing anything regarding 5500 features? can i disable an individual drive from an electrical signal? is there an example where disabling using a configurable input would be advantageous or is it generally a legacy thing is it to make it easier to disable a single axis of a dual module? As i am using a MSO/MSF within the program i can still enable/disable the drive from the software so i still have control and the STO handles the safety side i would be interested to know the general opinion Thanks Andy ### Assistant: EDIT: modified text better highlighted to avoid confusion -FL Hello Fentiman Moving from K5700 to K5500 is not a very common move :) there is some important differences . K5700 needs a Power supply , where K5500 do not , it's more a stand alone drive with some DC bus sharing capability. And K5500 is a single axes drive. Kinetix 5500 Servo Drives User Manual (rockwellautomation.com) K5500 do not support (for the most important topic): MP Motors , only VP motors are supported EDIT: MP are supported with a converter Kit No advanced safety feature , Only wired STO or Networked depending of the Version. Do not support the same advanced tuning features K5500 do not have an auxiliary encoder input Support 2 digital inputs (4 for the K5700) Regarding your question : can i disable an individual drive from an electrical signal? you can Enable or Disable the drive with the instruction MSO or MSF . as you said the STO can be also used. Why do you need a hard wire Enable ? If you need MP motor control , look also at the K5300 drive regards \n

### Human: Powerflex 525 - Ethernet IP - Third Party PLC Hello All, I'm new to this forum, and have searched for documentation regarding the Powerflex 525 and the addressed / registers of the EDS File. I have used the 0001009600090500.eds file, downloadaded from the rockwell site. I use the embedded ethernet port and use the drive in single drive mode. I also see a different eds file folder EDS_PF525_V6 which also contains PF525 single drive mode, embedded ethernet port eds files? WHat is the different. If you add a drive in RSLogix you can see all bits named correctly (Speed reference, start, stop, at speed, etc) This is not the case when I import the EDS file. And cannot find this in the documentation, where can I find this? I use a Unilogic PLC. I want to have at least the following data: CMD Start CMD Stop (or not start) CMD Reset STS At Speed STS Running STS Faulted STS Actual SPeed STS Error code ### Assistant: Hi de Vries, The Add-On Profile (AOP) is what organizes the PF525 data into user-friendly tags, not the EDS. (Unless I am way off-base?) Here is a technote on using the PF525 as a generic device that tells you which bytes correspond to each of the registers you mentioned (e.g. CMD Start, Speed Reference, etc.): QA54660 Also see appendix D of the user manual: https://literature.rockwellautomation.com/idc/groups/literature/documents/um/520com-um001_-en-e.pdf Regards, RM \n


### Human: using a single servo for multiple functions I have a servo that operates a module on a machine and this module is not always used on all products. if the module (but not the servo) was removed when not in use and potentially an alternate module fitted, would it be possible to have 2 sets of parameters for the same servo? Could i load a different set depending on the product that has been selected to run enabling me to use the same servo/drive (assuming it was the correct size)? Would it be possible use two axis tags (one for each module) that would write into the selected axis tag structure upon product selection? Or would I need to make the 2 modules virtual axis that would gear to the physical axis depending upon product selection? It would be good to know any thoughts on this topic Thanks Andy ### Assistant: Hello Andy, So if I understand you would like to change the Axis parameters of your servo , to adapt to a different mechanical set that change depending of the production batch that you are doing... correct? If it's what you would like to do, yes it is possible , you have different options by using GSV/SSV instructions and in some cases MSG for the different parameters that you need to change , like Scaling, Tuning, inertia...etc You must do it axis disable. There is other solutions but they are mostly based on the same principal. You could also Inhibit and Un-inhibit axes... I guess you could find some info on RAKB Using the 2 virtual axis that you gear alternatively to the physical , can be a solution, if the mechanism have the same specificity , so you will not have to retune your axis (unless you have Load observer and Tracking notch to compensate if you are still in the BW of those features). Regards \n


### Human: PF525 driving a flywheel We have several flywheel-driven machines. About a year ago, we installed a 15HP Powerflex 525 drive in simple V/Hz mode with DB resistors on one of the machines. It's been running great for that whole time. We have it set up so the STOP input (terminal 1) is wired through the DB resistor thermostats, input 2 is Run FWD ,and input 3 is Run REV. Since it's replacing an across-the-line reversing starter that's in the midst of a bunch of hard-wired relay logic, Relay 1 is Ready/fault and will cause the relays that control inputs 2 and 3 to drop if the drive faults. This arrangement has been running fine on machine ### Assistant: Joe E. Try swapping the motors. If the second motor is low inertia (compared to the first motor), it might be more difficult for the VFD to regulate the motor speed. \n


### Human: PF525 utilizing a Line Reactor I'm curious if it's possible (and safe) to group multiple PF525 drives on a single line reactor. I am designing a panel that contains fourteen (14) 10hp drives and ideally, I don't want to have a line reactor for each individual drive. Can I group 2-3 drives per line reactor, and if so, how do I go about sizing the correct line reactor? Is it as simple as combining the FLA of the 2-3 drives for the individual line reactor or is there some other calculation to utilize? ### Assistant: Hello Mark, Please review QA13774 All of the relevant information is available through the technote. Thanks \n


### Human: Powerflex755 Fault 20 TorqPrv Spd Band One of our 755 drives keeps giving Fault 20 the TorqPrv Spd Band fault. As the system its engaging its coming down or up it slows down. We have changed the encoder cards and the brake relays which fixes the fault for a couple of days but then it faults out again. Is it necessary to switch out the entire drive completely or is there another troubleshooting step to take? thanks ### Assistant: Hello Sigala, Have you seen technote QA15459 There are some adjustments that can be made explained in the technote that might help. Thanks \n


### Human: PowerFlex 525 Difference NP RPM vz Output RPM Hello. May I ask you for one information about status data from Powerflex 525. We setup RPm according nameplate of motor to 1440 rpm. But when we start FD and run at 50Hz/100%. Actual value of RPM P15 Output RPM is 1500 RPM. Location is Europe, so the value max. herts is set up to 50Hz. Can you explain the difference. Thank you. ### Assistant: Hello Harajdic, A couple of questions. Have you tuned the drive to the motor using P040 [Autotune] What is the value of parameter d375 [Speed Feedback] when running at full speed? Are you using an encoder? What is the value of p039[Torque Perf Mode] Thanks \n


### Human: PowerFlex 700S Migration Dear good afternoon, I wanted to know what is the exact replacement for my PowerFlex 700S drives, since on the Rockwell page only power flex 755TS appears generically, please your support to be able to make the correct replacement. 20DC037A0EYNANANE 20DC022A0EYNANANE 20DC5P0A0EYNANANE I must highlight that I have my drives in an ethernet network with my 1756-L61 V16 processor, 1 1756-ENBT module and Point IO 1734-AENT. In addition, each drive controls 1 motor with an incremental encoder with the following characteristics: Thank you very much for your help. ### Assistant: Hello, please note that the local Rockwell distributor or commercial channel should be the first point of contact to discuss the exact replacement of a PowerFlex 700S phase II drive with a more modern drive. Please also note that the parameter set, terminal connections, physical dimensions and other features may not be the same between the currently obsolete 700S phase II drive and the newer PowerFlex drive chosen, which means that additional engineering design time and considerations should be taken into account, as the migration will not be a like for like drive replacement. PowerFlex 700S Drive Frames 1…6 to PowerFlex 755TS Drive Frames 1…6 is a very comprehensive guide that can help to specify more precisely the exact replacement. In particular, there are some tables in chapter 1 that correlate the power ratings of the drives, adding dimensions. That could be a good starting point for the selection of the right 755TS drive to source. Regards, \n


### Human: Kinetix 5500 Servo Driver H015 FLT S25…PRECHARGE FAILURE Hi, I had two kinetix 5500 servo driver H015 will show FLT S25…PRECHARGE FAILURE error on the drive whenever it being power up with DC 24V & single phase AC 240V simultaneously. I read across the user manual for the power up sequence. It required to provide DC 24V first then wait until it turn to PRECHARGE state only provide the single phase AC 240V. I follow with this method and the error didn't not show & motor show RUNNING state. But I feel quite weird for the machine & driver that need to turn on DC & AC voltage at different time. Anyone meet this issue & any solutions I can deal with this condition so that my panel able to power on the DC & AC at the same time & the servo driver able to run? ### Assistant: Hello, the power up sequence of the Kinetix 5500 servo drive, as mentioned early on this thread, is clearly documented on Publication Kinetix 5500 Servo Drives User Manual. By design specifications, the Kinetix 5500 servo drive needs to be powered up following that order. After applying the 24V DC control power, the LCD display begins the startup sequence, which includes a self test that requires a few seconds, before the axis state can reach the PRECHARGE state. Is that time when three phase AC power should be applied. If the AC voltage and DC voltage are applied at the same time, the shunt resistor circuitry may not enable at the right time, which could generate these type of nuisance faults. More information about this via this technical note Kinetix 5500 No display or lights, not powering up . \n


### Human: I need the internal circuit diagram of the device kinetix 5500 Hello I live in Iran And due to international sanctions, I don't have access to authorized rockwell automation repair centers I have a kinetix 5500 model drive which encountered error s11 inv overtemp To repair this drive, I need the circuit diagram inside the drive Please help me?

### Human: powerflex variable frequency drive 753 EDIT: moved to Drives and Motion community -FL Hi, I was using a powerflex 753 cat no -20F11 N D 022 JA0NNNNN and recently it burned . On investigation I found out that this frequency drive is designed for 480 v 60 hz input whereas power input provided was 400 v 50 hz . Has it burned due to wrong input as I later found out that for 400 v 50 hz cat no should be -20F11 N C 022 JA0NNNNN. Please clarify. ### Assistant: Hello Mohan, The VSD has the capability of swapping between 400V and 480V using parameter 305. Parameter 305 is set to either 400V or 480V depending on the Catalog number of the VSD. This lead me to believe that the voltage range of the VSD is capable of 400V or 480V. This is explained in QA46486 and QA16097 I would suggest send the VSD to the repair shop, they will provide a detailed repair report indicating what components failed. Hope this helps. \n


### Human: How to do parameter changes in Armorstart St 284GS like Powerflex. I am new to Armorstart ST 284GS drives. I cound not find any software to configure the parameter for this drive. How to change the parameter? Any software avaialble? in Studio 5000 V33 , Armostart AOP 1.0068 using . there is no parameter option avaiable. ### Assistant: Hi PMKG, ArmorStart ST 284GS AOP is available from Studio 5000 V24 to last. The configuration pages of Chapter 6 should be shown in the project. If not, the AOP is corrupted. Chapter 6 starting page 88: ArmorStart ST Motor Controller with Integrated Safety - User Manual, publication 280ES-UM002. The configuration is slightly different that a PowerFlex, but all parameters can set. \n


### Human: ArmorStart 284GS Internal communication error I Connected to 24V Powersupply. 480V is not Supplied to the Drive. I can see in Rslinx but its not communicating with PLC. Web page also not opening. Is it really 480V required for communication? Note : it is Factory delivered drive. ### Assistant: Yep, this is my biggest complaint with the ArmorStarts, is they seem to require 480VAC to actually do anything, including set the IP address. -RM \n


### Human: PowerFlex 4M & PowerFlex523 4-20mA Input Hi Guys, I have 4 drives on the site: VSD 1, 3, 4 - PowerFlex4M VSD 2 - PowerFlex523 I'm having some issues with reading analog input (4-20mA) from my PowerFlex 4M 2.2kW drives. These analog signals comes from PLC analog output and I have confirmed with multimeter on the PLC output points that they are giving out correct mA. For eg: At 16mA, VSD 1,3,4 - Parameter d021 is reading around 80%, instead of 75%. t213 - 0, t214 - 100 VSD2 - Parameter d361 is reading around 75% as it should. Since all PowerFlex 4M are doing the same behaviour, I might be missing out on some settings? Any advice would be appreciated. Thank You. Reference: 22F-UM001D-EN-E PowerFlex 4M Adjustable Frequency AC Drive FRN 1.xx - 2.xx User Manual (rockwellautomation.com) 520-UM001I-EN-E PowerFlex 520-Series Adjustable Frequency AC Drive User Manual (rexel-cdn.com) ### Assistant: Hello Maung, It seems the scaling is slightly off. I think in the 4M the scaling is based off the min and max frequency parameters P104 and P105 if I am not mistaken. These parameters may need some slight adjustments to align your VSD speed control with the PF525. Hope this helps. \n


### Human: Kinetix 5300 Fault - PWM Frequency Reduced Hello, When I trigger the MSO block of the Kinetix 5300 drive, I get the 'Physical Axis Fault - PWM Frequency Reduced' error after a short while, even if I do nothing. I couldn't find anything about this problem and its solution in the docs. Does anyone have information? ### Assistant: Hello Gamze, This is a very strange fault indeed, because you can't adjust the PWM, so it must be a protection . It seem that the system foldback due to an overtemperature... but never seen this before Some questions for you : Is it a new Drive ? Check the drive temperature (you can check the Drive Temp on the drive Web page.) did there is any load attached on the motor ? if yes disconnect the motor from the load. and test again Run an Hookup test load disconnected and them an autotuning Make also sure that you have the latest FW on the drive. What is the drive and Motor ref ? Regards \n


### Human: Kinetix 5500 Home and registration input Hi i have a Kinetix 5500 drive where i require 2 registration sensors and a home switch. with the Kinetix 5500 drive you have 2 inputs available and these inputs can be selected as the functions DI1 - Home & Registration 1 DI2 - Registration 2 When using the Home & registration input is it plausible to use 2 sensors for 1 input or is there a better way by using another input for the 3rd sensor on remote IO or the main PLC rack ive tried searching the RKB but cant find anything Thanks Andy ### Assistant: Hello @ndy. I never tested 2 different senors on the 1st input of the K5500. Look in the manual 2198-UM001M to see if the internal digital input circuitry is compatible with the sensors that you would like to use (Page62). To avoid damage on the output of the 2nd sensor if the 1st one is active , you can use diodes. But I never test it. The other options are the following, use a PLC digital input to generate the Home input. but in this case you have to create you're own Homing cycle. Or use a time stamped input to create a Soft registration input (more complex to implement), the 2nd option is not as good as a real registration for very dynamic application. regards \n


### Human: PF755 Increment /Decrement Speed using 0-10V Hi , Is it possible to increment the PF755 speed in fixed amount using a 0-10V or -10V to 10V i.e if the drive receives 10V it will increment the speed by 2Hz and if it receives -10V the speed will decrement by 2Hz . I know it is possible using DI assignment but PF755 has only one input and that input is assigned to Run and dont have a seprate I/O card . Also since it is standalone VFD control over ethernet is not possible . We have a spring return Selector Switch which if turned in one Direction speed should increment by 2Hz and if it turned to another it should decrease by 2Hz. Can i connect a analog input to the drive through this such that drive receives +/-10V and accordingly increment/decrement speed by 2Hz ### Assistant: Hello, as pointed out on your initial post, the implementation of that application requirement would be possible configuring the MOP (Motor Operated Potentiometer) feature of the PowerFlex 755 with the help of 2 digital inputs. In the scenario presented, it looks like there are not spare inputs available to be used, so the straight forward implementation of the MOP feature will not be possible. To my knowledge, based on the MOP block diagram below, there is no indication that the switching of a +/- 10V analogue input will be triggering the 2Hz increase or decrease sought after on this application. More information on the MOP feature is available via chapter 6 of PowerFlex 750-Series AC Drives, Reference Manual Another possibility could be exploring if some sort of drive embedded DeviceLogix code could be implemented to mimic the MOP functionality of the MOP block diagram above. As any code creation task, this could be a time consuming exercise that may pose a challenge on its own, due to the real possibility of non being able to manipulate or access certain signals/registers on the drive via DeviceLogix. \n

### Human: Powerflex 755 Electricity Shutdown Parameter Problem Hello Everyone, I have a strange problem on Powerflex 755. We use 15kW 30 A drive and do incremental position control. When we download parameters to the drive, the motor works fine but after we cut off the power and start the drive, the motor vibrates and runs loudly. After we upload backup file again and the motor starts fine again and after we cut off the power and start the drive, the motor vibrates and runs loudly again. There is a loop. Same thing for 20-HIM-A6. We can't see any parameter after cut off power. When we upload backup file again we can see parameters. How can we fix this problem? Can you help me? ### Assistant: Hello Emre, Do you have a Logix PLC communicating to this VFD via Ethernet? If so, do you have Automatic Device Configuration (ADC) enabled? I ask because if you are connected via Ethernet to a Logix processor and have ADC enabled, the PLC memory card is storing a copy of the VFD programming. So any VFD programming changes that you do AT THE DRIVE with the HIM module must then be uploaded into the PLC program. If not, then whenever control power is cycled to the VFD, the ADC system will see that the programming in the VFD is different from that in its memory and restore the programming from its memory back into the VFD, wiping out any changes you may have made locally using the HIM. \n


### Human: how to transfer servo axis data from one plc to another plc in studio 5000 im have a servo in one machine connected to a AB PLC. and i want to make that servo as master servo and synchronize the two other servos which are present in another machine with different AB PLC as slave WRT to the master servo from first machine. so how i can transfer the axis data from one PLC to ano ther PLC as i want to use MAG instruction to build electronic gearing. ### Assistant: Hello Inkar, In your case you have 2 options. Option 1: in the Master machine you can produce this axis over ethernet IP (supported starting Logix v32). them you can creat a virtual axis in the remote machine (slave) that consume the data from the Axis produced in the master machine. Then depending of your need you can Gear, Cam any of the remote machine to the Virtual slave that is sync to your master axis on the master machine. If your application is bellow V32, you will have to use a CIP sync AOI (much more complex), at this stage please engage a Rockwell Automation support. Option 2: Buy a CIP motion encoder , and install it on the Master Machine, this encoder will be connected on the Network and processor of the remote (slave)Machine. This encoder will be seen as a real CIP Motion axis in the remote Machine, you can them use this axis as a master for the other axis on this remote machine. Them you just have to creat a PCAM , MAG..etc between this encoder and the axis that you need to synchronise on this slave machine. The Option 2 is the easiest, but require some investment. But do not require modification of the code of the master machine. The Option 1 is the most complex to implement, even more if you have a Logix version bellow V32 and you don't want to upgrade to V32... without support I will not recommend this one Regards \n

### Human: Motion Control Bit Evaluation When Using Motion Instructions in Structured Text I am using some motion instructions in structured text and trying to get a good handle on when the .ER and .DN bits get set and how they need to be processed differently than in ladder. Does anyone have a good reference or any sample code (good code) from rockwell (or others) on how we should correctly look at the motion control bit status when used in structured text? (the structured text programming guide is a bit vague and lacks examples related to motion instructions) For example, the code below the intent is to: 1. check to see if registration needs to be disarmed 2. disarm registration 3. check for error 4. continue on... ***************** if (Ax_Infd1XfrBelt.RegEvent2ArmedStatus OR Ax_Infd1XfrBelt.RegEvent2Status) Then MDR(Ax_Infd1XfrBelt,MI_I1TBReg2MDR[0],2); if (MI_I1TBReg2MDR[0].ER) then EM_Infeed.I1TB.ShtTrack.Val_MtnInstrErr:=MI_I1TBReg2MDR[0].ERR; EM_Infeed.I1TB.ShtTrack.Val_MtnInstrExErr:=MI_I1TBReg2MDR[0].EXERR; end_if; end_if; ************* But questions come up... like 1. When does .ER bit get set? Before leaving line with MDR so it can be checked write after? or some other time later? 2. When does .DN bit get set? In ladder it says it may take a few scans... is it the same in structured text? Does that mean I need to set motion instruction and then go wait for either .DN or .ER before continuing? Is there any cases where neither get set in a reasonable time... If anyone has done a lot of motion instructions in Structured text and has a guide or best practices, I would appreciate some feedback Thanks ### Assistant: Hello Eric Bryant, 1st you should find details for each motion instructions in this manual. Those tags are part of the motion control tag that is associated with each Motion instruction. it's a status of the instruction. they are not mandatory to use, but they can help a lot in your application. The .ER is for the instruction Error status tag, and comes with the extended error code .ERR. So if you have a fault on your instruction (.ER) it means that your instruction have not been executed correctly (state, configuration...etc), that does not mean that you axis is in fault. so Monitor this tag to make sure that all works perfectly in your code. Them if .ER occurs monitor .ERR , the tag value is a code for fault description (all details in the like that I provided)... but once again this is not required, but can be very handy for maintenance. Regarding the .DN it tells you that the instruction have been executed , does not mean that your action is finish, this is why you also have the .IP or .PC... The .DN can be used like an interlock, you can also reset it when needed , this way you can easily manage the start of the your motion instruction, if you interlock it with a .DN. again all details in the link that i have provided. So what ever the type of language you use, the usage of those tag is the same. if you understand the meaning of those tag and how the behave , you can decide to use them in your code to achieve your goal. but there no general rules about those tags. Let me know if you need more detail Maybe someone will add some additional details regards Vincent \n

### Human: PF755 with UFB feedback card connected to full digital SSI IFM encoder model RM8001. Bad velocity feedback. PF755 20G11NC060JA0NNN, firmware 16.002 20-750-UFB-1, firmware 1.015 I'm testing a lifting application. In this application is very importat to know the position of the load. In order to know load position, we read feedback position of motor encoder. If we use a simple incremental encoder, every drive disconnection implies to readjust home position. To avoid this, we choose an absolute encoder. To reduce the number of wires from the encoder to the drive, we choose an absolute full digital SSI encoder (IFM model RM8001). In the drive we have a 20-750-UFB-1 feedback card. This card is able to read SSI devices. We connecte SSI encoder according to Document ID BF14673. But parameter 6 equal to 9 (SSI FD ChX) We programmed UFB card according to Document ID QA28660 Parameter equal to 9 (SSI FD ChX) Parameter 8 equal to 0 Parameter 20 equall to 4 (Gray code) Parameter 21 equal to 12 (4096-12 bits per revolution) Parameter 22 equal to 13 (8192-13 bit number of revolutions) Now, UFB car shows the position from encoder with no errors. If i move drive the count changes increasing or decreasing depending movement up or down. The next step, i configure drive. I follow Document ID QA15265. In this document, after basic motor data programing. Is necessary to program feedback data. But prior to this we must check feedbak. So we write in parameter 132 a 40005 (Port4: Feedback 0) then, i move in VHz the drive monitoring paramenter 134. PROBLEM Te speed i see in parameter 134 is bad. Not stable, like ramdom. Numbers i'm not able to understand. For example, i move drive at +10Hz. In parameter 134 appear number between 0 and 1500 more or less. The accuracy is better if i write in paramenter 133 a 7 (3R/S noise) then in 134 i read from 0 to 16. In parameter 26 of UFB card i tested all possible values to sampling time, but results are simmilar. Where do you think is my problem? Thanks ### Assistant: Have you tuned the drive or the speed loop yet? Based on your pretty detailed post (thank you, btw) you really only got to the point where you are doing a direction check. and have not actually tuned the drive or the speed loop in QA15265. Based on your post, this is where you stopped: Which is only to check the direction of the encoder, not a final speed feedback check. If I misread your post, I apologize. Regards, RM \n


### Human: Powerflex 700s Phase II - Disable Motion Control Hello. We have a Powerflex 700s phase II firmware 4.002, but the enconder card is burned. We want to disable it to use the Drive wihout motion control. We try some configurations found it in the web, but the parameters mentioned are different of the parameters that we have in the Drive. When we start it from the HIM, the Drive stop immediatly but we don't have any failure. We changes the parameters: 222 - Sensorless [Mtr Fdbk Sel Pri] 223 - Motor Sim [Mtr Fdbk Sel Alt] 485 - V/Hz [Motor Control Mode] We don't have any failure before we try to start the Drive. Any sugestion or Do you know if is it posible to use it whitout motion control? Thank you. ### Assistant: Hello Arredondo, Parameter 677 stop owner should indicate where the stop command is coming from. This should help in tackling this issue. Thanks \n


### Human: PowerFlex 70. Migrating from 20-COMM-D to 20-COMM-E. Retaining original VFD's. I have an MCC full of PowerFlex 70s that I need to cut over to Ethernet. I need to retain the existing drives. Does anybody have any experience, how-to's, or input as how to proceed. Stratix 5700's in place, cables pulled. Just need to swap the comms modules and make them work. ### Assistant: What controller are you using? I would suggest making sure the ethernet switch is configured prior to attempting the switchover. I feel like I fight them (Stratix5700) a lot during initial commissioning. Regards, RM \n


### Human: Kinetix 5500 module fault Hello Everyone, Now the system have 4 servos ( Kinetix 5500), all of them are running good, but sometimes one of them has the module fault.so this servo will go to stopped status. Can you give me suggestion how to find the reason, how to check it. Thank you ### Assistant: Hello Carry, More details on the fault would be valuable Please provide the default number on the K5500 display and / or a screen shot of the module fault in Logix 5000. regards \n
