<s>[INST] PowerFlex DC line voltage operation ranges Summary: Can the PFDC bridge operate with line voltages other than given in specs We have many situations in the elevator industry where the armature voltage of a given machine is above 240, and below 500 vdc. An example is one I am working on now where the armature voltage is 315 vdc. The existing machine is operating with an AB1395 drive, and it is fed by power from an isolation transformer with a secondary of 315 vac. This is a common practice, to help optimize form factor, and to help in sizing the transformer. So my question is, can I now use a PFDC drive with the same line voltage feeding the SCR bridge? There is no information in the literature. [/INST] Technical document for the PF-DC http://literature.rockwellautomation.com/idc/groups/literature/documents/td/20p-td001_-en-p.pdf What I see in this document is that your 315VDC motors fall in a hole for the Rockwell PF-DC products. This is DEFINITELY a time you should call Rockwell Tech Support and talk with the drives group: Dial 440-646-3434 Option 3 for Tech Support Option 1 for Direct Dial Option 1 to enter code Code 511 for DC Drives \\n </s> |
<s>[INST] PF700S - Fault 41 RideThru Timeout I have a 2Hp PF700S powered off of an NRU/RGU (so it is not rectifying AC to DC, it is supplied off of a DC bus). The motor is running about 127RPM, and is overhauled slightly so it runs ~ -12%FLT. There is some variability in the overhauling load. I have recently started seeing a fault 41, RideThru Timeout. This fault indicates that the drive has been in a bus loss ridethrough for more than 2 sec. Since I don't have AC supply to the drive and none of the other drives on the NRU/RGU are having faults, I assume that this is not truly the cause. Could I experience this fault if the drive runs at zero torque for some period of time? The motor does not have an encoder, and Par 485 = 0 (FOC).

<s>[INST] Meaning of Displayed current value on VFD Hi, I'm using PowerFlex40 VFD to drive a 3 phase induction motor. I have a basic doubt. In VFD display parameter d003 output current is shown. Now My question is which is this current. I can connect motor in STAR or DELTA configuration and current will be different in both the cases (I mean Phase and Line current values). Also there are three windings U,V and W in motor. So is it the case that VFD is delivering same current to all 3 Motor windings (just 120 degree apart ) and it is that current ? Also is this the RMS or PEAK or AVERAGE current ? [/INST] Hello, d003[Output Current] is the total output current present at terminals T1, T2 and T3 of the drive, as measured and calculated by the internal drive circuitry. The total output current can be defined as: where Torque Current is the amount of current in phase with the fundamental voltage component and Flux Current is the amount of current that is out of phase with the fundamental voltage component. Torque Current and Flux current are not available from the PowerFlex 40 drive (there are other drives from the Rockwell portfolio that provide feedback on Torque Current and Flux Current via read only parameters). It is expected the value of parameter d003 [Output Current] to be different depending on the internal arrangement of the motor windings (STAR or DELTA). Those values should be in accordance with the relevant formulae for voltage and current in typical Start and Delta motor connections. Please note that the drive will not be aware of how the motor windings are internally connected. The drive will be able to provide an output voltage up to the same level as the supply voltage (the drive will not be able to provide more voltage out than the voltage coming in). It is important to check the specifications of the motor to make sure that the motor windings in the desired connection (STAR or DELTA) are rated and capable of withstanding the output voltage provided by the drive. The inverter section of a variable speed drive does not produce sinusoidal voltage waveform, but rather a series of voltage pulses created from the DC bus, also known as PWM (Pulse Width Modulation). More information on this can be checked via this document Induction Motor Winding Voltage and Inverter Drive Output Voltage Relationship Those voltage pulses will be applied to the motor windings and there will be a flow of current from the drive output terminals T1, T2 and T3 through the inductance of the motor windings. The value of parameter d003 [Output Current] is provided in Amps with two decimal places. This value is filtered by the internal electronics of the drive and is an averaged value of the real time PWM current waveform. \\n </s> |

<s>[INST] PLC programming mode status to SCADA. I want to sent a high signal to SCADA when PLC is in programming mode.Somebody else made programs and I am commissioning now. There is a tag for CPU1 and CPU2 programmming mode in tag table. I did crpss reference and I cannot find where from it came. Also I have a redudent L75 PLC. When I turn the key on CPU and made program mode, I did not get program mode tag high to HMI. Its value is 0 and not getting high.why? [/INST] In Program mode the program does not run, so no values will change. Here, I have used a GSV to get the Status of the controller. When the controller is in Program Mode, as shown, the instructions don't run, so the values are as they were when it was last in Run mode. You haven't said what SCADA system you are using. If you are using FactoryTalk View SE then there are some tags you can read to get the status. They begin with @ and you can find a list in the documentation. You could look at the @Mode tag. If you are using a different SCADA package, check its documentation. You could use GSV instructions an ladder to get information about the Controller status. You are using a redundant processor, so you ought to be able to get information about each controller from the Redundancy object. So if if the Secondary is in Program mode you should be able to find out.\n </s> |
<s>[INST] 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 [/INST] 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.

<s>[INST] Is it possible to create a function block in RSLogix 500 Pro? [/INST] RSLogix 500 only uses Ladder language, in routines. Only LAD2 is launched by the controller, and you should use the instruction JSR to launch the other ladder routines. There isn't a feature like Add-On Instructions in RSLogix 500.

<s>[INST] Question about motor driver information Summary: location for storing motor driver info Hi all, I have questions on motion control. Q1. what are the motor driver information? And what it means when people say 'putting all motor driver info on the PLC and have an auto download of driver info once an new driver is installed'? Please help me in details because I don't know much about motion control and PLC ( I am fresh in auto) Q2. what it means when people say 'put recipe system and info on the PLC and not on the HMI'? Thanks! [/INST] The PLCs that support CIP motion and control Powerflex 755 VFDs download all data to the drive on power-up and successful network connection. When a drive is used outside of CIP motion, basic motor data is not usually sent to the drive from the PLC. In fact, the minimum control one could do over Ethernet for a drive not used for CIP motion is a start/stop command and a speed reference. All other parameters (tuning gains, motor data, etc.) would have to be set at the drive. Additionally, Rockwell's recent versions of PLCs can store the firmware of a drive (regardless of CIP motion or not). With the proper configuration in the PLC, this firmware can be downloaded to a drive automatically to a new drive replacing a failed one. \\n </s> |

<s>[INST] Camming 4 Real Axis & 2 Virtual Axis? I am using an L45 processor with two sercos cards and 7 axis total. 4 of these axis need to be cammed together, but not at the start of the process.

Later in the process, I cam virtual 1 to virtual 2 and then only jog virtual 1. All 6 move at that point. This seems to work ok, but I haven't run the machine much at this point. Is this the best way to do this?Does anyone know any problems that may crop up? [/INST] your only alternative is to cam axis 3 and axis 4 to virtual 1 vs. cam virtual 2 to virtual 1 in your second mode. Based on my experience (even though I haven't done what you are doing) it seems like what you have already done should work fine. I think the only thing...if you read some AB literature (it seems to be in the back of my mind I read somewhere) that you have a slight delay (probably un-noticable, except in extremely critical applications) where you are cascading these camming functions. I think this delay is equal to one trajectory calculation cycle.... maybe in mSec??? You'll have to do a little reading if you think it will matter in your application.

<s>[INST] Powerflex Drives Specifications When reading the Specifications for a Powerflex 750 Series Drive it states that in Flux Vector Torque Control Mode the specification is +/- 2% 2500 rads/s bandwidth with an encoder and +/- 5% 600 rads/s bandwidth without an encoder I understand the percent is percent of total base torque. So if using a 60 n-m motor the 2% is 1.2 n-m or 5% is 3.0 n-m. I just don't understand what radians per second bandwidth has to modify the situation. [/INST] Hello, think of bandwidth in this context as how quick the internal Torque Loop inside the drive can work. The higher the bandwidth, the faster the torque loop can react to torque variations. The faster the torque loop is, the more accurate the torque regulation will be as well. The speed and torque closed loops inside the drive are implemented via the firmware. Typically the input of the torque loop comes from the output of the speed loop and the regulation of the torque signal occurs much faster than the speed signal. This is normal. Bandwidth can also be measured in Hz. 1 Hz = 6.28 rad/s. Think of the bandwidth in terms of frequency domain rather than time domain. So for example if signal to control (in this case Torque over time) is likely to change very quickly in the time domain, then the higher the bandwidth of the system the better chances the control loop of the system will have to control more accurately the output torque within tighter tolerances.

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? [/INST] 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.

<s>[INST] Compact L18ERM With Kinetix 350 Over IP Summary: Drives not recognised in Linx; Download from Studio puts drives in error Oh heck, this is proving to be a trial. System set-up is an L18ERM, f/w 21.11, lined to two Kinetix350 amplifiers, f/w 1.55, driving two linear drives. Comms is via Ethernet/IP. Amplifiers are set up as 192.168.1.xx, gateway 0.0.0.0. PLC is set to 192.168.1.xx. Once the kit is connected together, I can ping everything successfully on the network. If I now look in RSLinx (Classic), under the ethernet driver, I see the PLC. If I enter the IP address of the amplifiers manually, then they appear eventually, but are unknown devices and red-crossed. At this point, they still respond to a ping. All three LEDs on the front of the drive are flashing green. OK, I set up Studio5000 with the PLC and amplifiers, use the motor catalogue number to set up the amplifiers. I create a motion group and assign the amplifiers to the group and all is well. This configuration is then downloaded to the PLC, and by definition, the Kinetix drives. The PLC is quite happy with the configuration and can be switched between run and stop with no complaints. The drives however are definitely not happy. The network LED is solid green. The other two are flashing red. The drive shows a fault indicating motor over-temperature (the motors haven't been run at this point!) and can't be tuned or tested in any way from Studio because the software reports that the axis are not configured. RSLinx still shows the drives as unknown devices and red-crossed So now what? I've exhausted my meagre knowledge of IP and Rockwell and can't see that I've done anything wrong. My gut feel is that this is a firmware problem, but the latest revision of firmware for the amplifiers available from ab.com is 1.055 - the amplifiers were shipped with 1.55. Any thoughts, comments or laughter would help at the moment. My client has customers coming to see this system running on Monday (ha ha - why not commit to this when the R&D and commissioning is complete????) so feedback would be great. Many thanks, John [/INST] First question would be what version of RSLinx you're using. Next, I'd suggest downloading the K350 EDS files from Rockwell. That MIGHT help. Next, doesn't the K350 have a web page? If you access one of your K350s with a web browser (HTTP://192.168.1.xx) do you get anything? Just because you downloaded the program successfully to the PLC does NOT mean the configurations got to the drives. The fact that Linx can't really see them says it did not get there. How is everything networked? All devices connected to a central switch? What sort of switch (managed, unmanaged, what manufacturer)? If you want faster communications, you're welcome to communicate via email or even phone if you're USA based. I'll send you contact information privately. \\n </s> |

My issue is we don't have good control over the stack location. I was wondering if there was a way for the Kinetix drive to find the stack location and perform its location based off its learned location. I'm envisioning that when the stack is loaded, the crowders would advance with low torque toward the stack. When the drive senses a jump in current, it would record the location and base its crowding operation off that location. [/INST] What you try to do should be possible, this will require some code in your Logix controller, and can be challenging. You also could use the VTS to do this (virtual Torque Sensor). There is also a very common way to locate the position of an item that is unknown, it's the registration sensor. You can connect to the drive an accurate sensor that will detect the presence of the item, and take a picture (registration) of the actual position of your axis. since you know the relative position of your sensor (HW location) and the position of your axis when the item trigger the sensor you know now the position of your item relative to the actual axis location. So you can control move your axis to an accurate position relative to your item. this require some code in Logix aswell.\n </s> |

<s>[INST] Coordinating 2 axes, MCLM, MAG, MAM & MAJ I need to be able to move 2 axes simultaneously with a defined relationship between them (the axes are at right angles, and the angle of the trajectory with respect to 1 of the axes is defined). To do a move of a predetermined distance it seems my best bet is to use a MCLM instruction (although I guess I could use MAG and MAM to gear the axes together and then move one of them). To allow the operator to jog the axes I think my only option is to use MAG and MAJ? Having geared the axes together using a MAG do I then just execute a MAJ on one of the axes and the other will automatically follow it? Presumably the .ER bit on the MAJ instruction tag will only be set if there is an error on the master axis? Does a Motion Axis Stop (MAS) 'disconnect' the 2 axes so that they can move independently? If not then what does? A bit later... I guess another option is to create a virtual axis and gear the 2 real axes to that. I wonder what the pros & cons are of the different approaches? Mike [/INST] If you define a coordinate system, axis 2 does not automatically follow axis 1 in a jog. The two axis are only going to be together when you execute the MCLM or MCCM instructions. For operator jogging the two axis together will require the MAG. Having geared the axes together using a MAG do I then just execute a MAJ on one of the axes and the other will automatically follow it? The MAJ is executed for the master and then the slave will follow at the gear ratio. If you MAJ the slave, it moves by itself. Presumably the .ER bit on the MAJ instruction tag will only be set if there is an error on the master axis? The .ER bit simply means that there was an error in the MAJ instruction. It does not indicate that there was a physical error with either of the axis, unless either axis has a particular error and that causes the instruction to fault. Does a Motion Axis Stop (MAS) 'disconnect' the 2 axes so that they can move independently? If not then what does? The MAS can 'disconnect' the gearing if the Stop Type is set to ALL or GEAR. If the Stop Type is just set to Jog for the master then they both stop, but both will move again for the next motion command on the Master. I guess another option is to create a virtual axis and gear the 2 real axes to that. I wonder what the pros & cons are of the different approaches? There is really no big difference in using the virtual to control the other two axis unless your automatic mode is for a coordinate system and the manual operator jog is for just jogging the two axis in a gear mode. That might make your programming more organized, but doesn't effect the timing or accuracy of the moves. \\n </s> |

[/INST] Try adding an MAS (Motion Axis Stop) before issuing the MSF (Motion Servo OFF). One would expect some unwanted dynamics if you're allowing the brake to activate while the motor is still turning; servo brakes are generally holding brakes, not stopping brakes. I would suggest issuing the MAS, verify that the axis stopped by checking for zero speed (I think I remember that drive has a zero speed bit in the axis parameters already), then issue the MSF. If the drive definition doesn't have zero speed bit, it's easy enough to use a LIM command with axis velocity. \\n </s> |

<s>[INST] How to forcibly reset counts in a 20-750-ENC1 encoder option Summary: Is there a programmatic method to reset the current count of the encoder board? This is a motion application using a CIP-Motion PowerFlex 755 drive with a standard incremental encoder.. In general it works quite well. But the trend of position and velocity that I've been watching worries me at times - velocity becoming ragged and unstable at times.. Passive rehoming of the axis doesn't reset the underlying encoder count, but I may have one of the setup options wrong for doing so. My Axis Travel option is set for Unlimited, therefore the Unwind option isn't available for setting. It's configured this way because that was the default - and I didn't mess with anything that didn't appear to need messing with. As the encoder values increment toward very high integer values, the velocity trace (on a trend) becomes increasingly ragged. Restarting the drive causes the encoder to reset to zero, and the raggedness disappears. My theory is that encoder values that correlate into floating point values (positions and velocities) begin to lose numeric precision when derived from very large integer values. There may be a variety of more elegant ways to solve the problem (and I'd be interested to hear them all), but my brute force method would be to just reach in and reset the encoder. Is there a way to programmatically control the encoder board's count? Is it through an SSV? Or a motion instruction? Or explicit message? Or some other clever thing that hasn't occurred to me? My exact application configuration is contained in an earlier post. The sparseness of this post is an attempt not to be redundant with those details (if relevant).

<s>[INST] PowerFlex 523 - static vs dynamic autotune IR Voltage Drop Hello, We have a few PowerFlex 523 drives, all setup in the same manner and connected to identical motors. Static autotune was done on all of them and as a result the parameter 496 (IR Voltage Drop) was automatically set by the drives to a value in the range 22-24 V, each drive having slightly different value. Then, dynamic autotune was run on two of these drives and the parameter 497 was automatically set on them as expected, but also these drives changed their parameter 496 to a completely different value - 40V. Is this normal for dynamic autotune to override parameter 496? The updated value was not just slightly different. Static autotune sets it to 23.8V, then dynamic autotune overrides it to 40V, the difference is about 16V. Is dynamic autotune able to sense the voltage drop better and hence updates this value or is this erroneous behavior? [/INST] Hi Nickolay, The Static Tune Par 70 =2 can be performed in SVC and FV modes (Par 35) no matter if motor has or not a feedback encoder. It usually gets a reasonable value for the most of applications. The Dynamic Tune Par 70 = 3 only returns valid results with FV with feedback, or SVC with uncoupled load. If your application doesn't have a feedback encoder, the best solution is the Static Tune. It is explained in page 61, speaking about the Par 70: PowerFlex 750-Series AC Drives - Programming Manual. Publication 750-PM001. Paragraph: Important: If using rotate tune for a Sensorless Vector (SV) mode, the motor should be uncoupled from the load or results may not be valid.

<s>[INST] Setting parameter 445 on 753 Summary: Sensitive level in terms of %Good day, I wish to activate the phase loss on the 753 drive and I have a few questions 1. What is the correct setting of output phase loss level ( parameter 445) 2. The default setting is 200, and 200 is equal to what percentage of phase loss? 3. The sensitivity is based on voltage? M. Mahao [/INST] https://rockwellautomation.custhelp.com/app/answers/detail/a_id/719367/page/1 According to this knowledgebase article: F21 is Output Phase Loss, which means that the current in one or more phases has been lost or remains below the threshold set in Parameter 445 [Out PhaseLossLvl] for one second. Decreasing the threshold in Parameter 445 [Out PhaseLossLvl] will make the drive less sensitive to tripping. This is usually necessary when the motor is smaller than the drive rating. Check for an open output contactor or any loss of connection between the drive and motor. However, I'm pretty sure that the value in P445 is NOT in units of current; otherwise, why would the default value be 200? I don't think it's percentage either. However, no where I can I find a good definition or method to set this value properly. To activate output phase loss, you need to set parameter 444 to something that is useful to you (either alarm or fault). Default setting is ignore. You should be able to view the knowledgebase article; it is tagged as being for everyone. \\n </s> |

<s>[INST] 5700 Motor cable plugs Hello, We recently installed some Kinetic 5700 series, D057 servo's. Installation and commissioning went well but after a few days of running we had a fault which turned out to have been caused by a motor plug coming out of the socket. Apparently this is a known issue and amplifiers which are of the B series rather than A series have used a different socket so that the sides of the plug are now meant to be gripped. But we have used the new connection kit and can't see any physical difference between the old and new motor plugs, you would of expected to see a raised dimple on the side of the plug to allow the new socket to grip the plug better. The old connection kit part number is 2198-KITCON-D057 and the new connection kit part number is -L. I have read the only document I can find regarding the difference between the two connection kits (Rockwell Automation Publication KNX-TD003H-EN-P - October 2021) but it only specifies which connection kit should be used for which series of amplifier (page 41). I am starting to think that the wrong plug has been put in the new connection kit (-L) that we have just received. Can anyone confirm if there is any difference between the plugs or not?

[/INST] 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 </s> |

<s>[INST] 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 [/INST] 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 </s> |

You've only given us a processor model, so you could use a K350 or a K5500 economically. But you've not said anything about voltage so no one could recommend more than that. You've given only torque, you've said nothing about the necessary speed. You've told us the type of mechanical setup, but nothing at all about reduction ratios, load, inertia, friction, cycle time, etc. You need to give us a LOT more information if you want useful recommendations from us. I suggest you use Rockwell's Motion Analyzer: https://motionanalyzer.rockwellautomation.com/ \\n </s> |
<s>[INST] Powerflex 525 VFD Summary: Powerflex 525: Not showing ADC optionI have 10 powerflex 525 module in my program and all of them have ADC option except for one VFD. I compared all setting with the one which has this option and everything looks same, Anyone can tell me what am I doing wrong here? [/INST] In the image you shared, we can see two different drive tabs. The one labeled VFD80205 shows firmware 5.002. The one labeled VFD80305 shows firmware version 5.001. Since you can't see the ADC branch for that drive, the first thing I'd try is flashing VFD80305 up to firmware 5.002 to see if that fixes the problem. \\n </s> |
