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

<s>[INST] Ultra 3000 error code 44 Is there an explanation of error code 44. The tech note i looked at references something about the current power cycle which does not make sense. What will cause the fault and how can you reset it. Does it require that you power down the entire system to clear it. [/INST] Prevention: Maintain encoder signal integrity, eliminate noise sources. and thats kind of a mash up a couple knowbase docs 36307 and 36895 When a lost motion fault occurs, the nonvolatile, absolute homed status (and Logix absolute reference) is cleared only if the drive has been homed during the current power cycle. This is because motion may have been lost prior to establishing the home position. When motion is lost and then the drive is homed, the home position will appear to change on the next power cycle by the amount of lost position. Therefore, the drive must be power cycled and then homed again. If the drive is homed, but not in the current power cycle, then the nonvolatile homed status is not cleared and only a drive reset is required after a lost motion fault. The drive will be correctly homed after the power cycle/reset. This applies to single and multiturn devices for stand alone and Logix applications. \\n </s> |

<s>[INST] Looking for a good example of speed/position stand alone master/slave for PF755 Hello, I have a customer that has an application with a dual shaft mixer where he is looking to keep the two shafts 180 degrees out of sync with one another using PF755 and absolute encoders as a stand alone application. Is there any supporting documentation for this or do you have any ideas on what would be the recommended way of approaching this. [/INST] The PF755 drives can do this - and technically you only need one PF755 - the other drive could be dumb as long as the master motor has encoder feedback. The slave drive would receive both the master feedback and slave feedback and do electronic gearing. However, it sounds like the 180-deg out of sync is required because the two shafts have the potential for physically interfering with each other? If this is true, you're getting into dangerous territory where it would be better to have a PLC and do CIP motion with both PF755 axes. While it's technically possible to do everything you need using devicelogix within the drive, doing all of the logic in a 1769-L18ERM CompactLogix processor is much, much, MUCH easier. So much so that the time you save easily pays for the cost of the L18ERM processor. \\n </s> |
<s>[INST] PF70 EC / PF700 VC DriveStatus_AtSpeed bit Hi, I am using a PF700 VC drive and two PF70 EC drives. In my ControlLogix PLC, I am communicating with these drives over Ethernet/IP via 20-COMM-E modules. In my logic, I'd like to make use of the DriveStatus_AtSpeed bit in each of these drives. I am finding that this DriveStatus_AtSpeed bit is constantly turning on and off, even though my speed is well within the range of what I would consider At Speed. Can anyone tell me if there is a parameter in these drives that I can adjust to make this DriveStatus_AtSpeed bit a little more forgiving? Thanks in advance, Paul [/INST] Paul, If the drive is operating in Speed Control Mode (Velocity Regulator), the _At Speed bit should not turn on and off when the drive is running! The Speed Regulation Control Loop's ONLY duty is to keep the drive running at the commanded frequency! If the drive is operating in Torque Control Mode(Torque Regulator), the situation you describe is normal since the Torque Regulation feature of the VFD reduces/increases the operating frequency in order to maintain constant Commanded Torque. The third scenario (probably the one your application applies within) uses a combination of the two above mentioned modes. You could call it Speed Limited Adjustable Torque operation. The drive will automatically switch from speed to torque mode (or from torque to speed) based on the dynamics of the motor/load. If this is true, you could try using the _Active bit of the Logix5000 Status Word (instead of _AtSpeed bit-which would turn on/off when the drive is running in Torque Regulation) in order to monitor the operating status of the VFD. The _Active bit will become true when the drive is started up and will remain on until a Stop command has been issued. \\n </s> |
<s>[INST] Servo motor moves without any order Hi everybody! I introduce me, I'm Camilo from Argentina, and first of all, sorry my english, it's awful, I know! Ok, I'm working in a depalletizer of bottles, what uses 11 servo motors AB, with Kinetix 6000 controllers. The plc is a ControlLogix 5561. The problem is that, after do the homing of a particular servo, it moves without any order at a really high speed. There is no instruction in the program in that moment who ask the servo to move. Well, I changed the homing mode, originally it was in torque mode, and now is in torque-marker mode. After do this (about one month ago), the problem didn't reappear. But yesterday, unexpectedly appears again. It really makes me nuts! Somebody might know what is the problem? Thanks in advance! [/INST] Your English is better than many who use it as their first language. No worries. Homing to a torque level - do you have any sort of speed limit set? The motor is going to run at its full speed looking for a load so it can build up to the torque value you set. If your axis is always in torque mode, that may be what's happening. While there is no overt motion command (JOG, or MAM, for instance), if it's on and has a torque command, it will speed up looking for that torque. The fact that your homing mode change fixed the problem temporarily points to two things - either something changed in software timing, or something changed physically on your machine. Can you share the ACD file here so we can take a look? \\n </s> |

<s>[INST] Servo Motors and Air Cylinders Hi, I'm looking for a way to make an air cylinder reach its extended position when my servo axis reaches a certain position. The cylinder and servo are 2 separate things. The servo is controlling an elevator type device (up/down) and the cylinder moves a knob in/out to the elevator. Since my cylinder takes n-seconds to reach its extended position (from retract) no mater what speed my servo goes, how can I make sure the cylinder reaches its extended position at the same time that my servo passes/stops at a certain position? I'm using an MAM for the servo. I'm thinking that after I start the MAM, there is a known motion profile for the servo drive controller to follow. Can I determine what position the servo will be at n-seconds before the end of the planned move? Or use some sort of output cam? Thanks, Denis. [/INST] It sounds like you do not have feedback from the air cylinder - you do not know its position as it moves. Without feedback, this is not going to be very precise. Your air cylinder speed is completely dependent on air pressure. Any changes or fluctuations are going to change your speed/position calculations. That said, if all you have is the time that it takes for the cylinder to extend, instead of using a Motion Axis Move (MAM) command, use a Motion Axis Time Cam (MATC) instruction. Look at the Logix help file for MATC to see how to use it. Also refer to the motion instruction reference manual: http://literature.rockwellautomation.com/idc/groups/literature/documents/rm/motion-rm002_-en-p.pdf \\n </s> |

<s>[INST] A large dumb drive Hi.Is there anyone else here who quite often needs a large drive (75kw - 315kw) that does not need a great lot of smarts. We do a lot of water pumping jobs so we really don't need all the bells and whistles. We just need rudimentary speed control, EMC filtering (built in) with an ethernet port and a 232 port that can talk modbus. The absence of all the smarts should keep the cost down which in this line of work is the most important thing.I thought the 400 range was going to fill this need but they do not even go up to 75kw.

If the VSD is over 40% of the transformer load at the PCC then an EMI filter is not the solution. You will need a passive harmonic filter ( add another $10k aust ), and the speed range would need to be above 60% or the capacitors will screw up the powerfactor.

After AutoTuning, suggested tuning gains are accepted (Position Bandwidth=3.69 hertz, Velocity Bandwidth 14.57 hertz). Issuing MSO closes loop, and puts drive into Running. Issuing MAJ causes normal running. Encoder feedback indicates motion in proper direction. MAS stops motion. Issuing MAM (Incremental 5 Ft.

Commanded Position show ramp, Commanded Velocity is trapezoidal. Actual position remains unchanged. Actual Velocity remains unchanged. Position errror remains zero throughout move profile. Modifying tuning parameters to include Velocity Feed Forward (100%) and reissuing MAM descibed above causes motion. The Motion Planner generates profile as described above. Actual Position moves to follow Commanded position, but with error. Actual Velocity approximates Commanded Velocity, but lags in time and rings badly. Most notably, no Position Error is calculated (or at least isn't displayed). Without a Position Error to act upon, Kp & Ki are ineffective. I tried several manual settings for Position Bandwidth, up to 30 hertz. without improvement. Effectively, the PI regulator in the drive is open loop. While observing the drive's position regulator diagram through Connected Components Workbench, I issed a MAM for a 15 ft. incremental move at 0.5 ft/sec. (longer in duration to watch the regulator work). No position error was generated. Also noted that Position Command [P723] didn't change at any point through the MAM execution. A note in the diagrams says When position control is inactive, Position Command [P723], Position EGR out [ P815], and Position Load Actual [P837] get loaded with Position Actual [P836]. This seems to point to a possible reason for 0 position error, as Psn Command sums with Psn Fdbk [P847] in the Position Feedback Scaling Block to generate Psn Error [P835]. I can't find a diagram showing what conditions contribute to position control being rendered inactive. All of the bits with Position Control [P721] are axis-controlled. I find nothing in the axis parameters that indicate how they're controlled. None of those bits explicitly say position control anyway. I find myself without a way to know when position control is active and when it's not, and no diagram to show the logic of it.

<s>[INST] Powerflex4, 40, 4M, 525 not following orders.... Summary: They do not follow cmd. freq. nor stop when told to. Hi all, Has anyone experienced their drives not following orders, such as command freq. (the drives tend to hunt around, even to go beyond max freq.) or what's worse, they don't stop when told to. When set to Decel to a stop, the drive tends to keep outputting a floating freq. (again, could be higher than max setting) and just stays running. One way to stop this is to set the drive to coast to a stop, but that's just a band aid. The drives are running as V/Hz. Now the problem seems to be related to the incoming 3ph power (imbalance from Edison), I can change up the three leads and the problem goes away sometimes, but I can't account for this when in the installed facility, this happens and the incoming seems fine and balanced. Any thoughts ?? Especially how to remedy this, I can't have drives not stopping on command. William [/INST] What is the slip frequency set to on each drive? \\n </s> |

<s>[INST] Ultra 5000 logic for a leading edge sensor for registration mark Ok, so I am one of the sick people that use the Ultra 5000, it fit the budget and the project design. I was wondering if anybody has any better logic than this for a registration sensor. The sensor starts off blocked, clears between parts, and then I want to start a function when the next part comes into position (i'm using it as a registration offset for a labeler). This is the code I'm using right now: while ((!InputGetState(2)) && (TimerDone(1)==0)) { pe4=0; } while((InputGetState(2)) && (TimerDone(1)==0)) { pe4=1; } while((!InputGetState(2)) && pe4==1 && (TimerDone(1)==0)) Just wondering if anybody has any better way to do it that isn't as verbose. Thanks [/INST] Can I assume from this logic that the final step to break out of these while loops is the Timer1 going done? Why aren't you utilizing the LatchOnIndex command? You apparently don't need the motor feedback from the latch but it would provide you with a function that operated automatically. In this example you check that the count has increased on the latch then store it in memory in case you want to run an operation off that memory with TriggerShot. if(LatchGetCount(1)!=CountBuffer && TriggerShot==0) { TriggerShot=1; CountBuffer=LatchGetCount(3); } if(TriggerShot==1 && TimerDone(1)==0) function_call(); I don't know your exact use case, but this is just another way to tackle it. I've got this running on many machines right now and we don't have any issues with the timing. I'm just concerned with all of your while statements that the code will be trapped in there and unable to run any error handling routines elsewhere in the code. \\n </s> |

<s>[INST] Gearing questions I have a 1000ppr encoder on axis 1 (Sorter Drive) and 1000ppr encoder on axis 2 (Cut-N-Two Drive). At any given point, I need to go to half speed on axis 2 then back up following axis 1 in a short distance. The application is a Planer Sorter and a Cut-N-Two Drive. Currently I use the PLC to do this but at higher speeds I think gearing might be better. We run about 140 lugs per min so the other chain (Cut-N-Two) needs to hold back to create that empty lug as the board will be cut in two and later on down the line, we lift one piece up and set in back down in the empty lug. Each lugspace is one full turn of the encoder and I'm thinking about using a MO2AE Motion Card. Any ideas?? Thanks [/INST] Gearing (MAG instruction) is a great way to go if you are not concerned about position-locking the slave axis to the master axis. It's very easy to use and change on the fly. If you need to maintain position lock, using MAPC and MCCP instructions (cam profiles) are the way to go. 1 to 1 cam profiles look exactly like 1 to 1 gearing, but executing an MAPC means that the slave starts following the master at the same place every time. This is not the case with gearing. \\n </s> |

<s>[INST] Latest Kinetix Firmware 1.116 help Rockwell published this firmware a couple of weeks ago. As of version 1.114 they added remote control of the brake control relay when the drive is disabled. This is from the release notes- This enhancement corresponds to Kinetix 6000 drive firmware revision 1.114 or later, when used with RSLogix 5000 software, version 17. When the drive is in the disabled state, the engagement and disengagement of the motor parking brake, if present, can be manually controlled. By setting the Brake Override IDN (16 bit, P00140) to a value of 1, the SERCOS Brake Enable/Disable IDN becomes writable and allows manual control of the motor parking brake. Once the drive is enabled, the Brake Override IDN is reset to 0, the parking brake is again under control of the axis, and the Brake Enable/Disable IDN becomes read-only, reflecting the current state of the parking brake. This description give you the new P00140 parameter and what it does but, what parameter do i write to, to control the brake? I think P00528 but this is just a guess based on the DriveExecutive file looking at the parameters in the Kinetix. Also what does it mean by disabled state? does the enable input need to be off (Axis.EnableInputStatus=0) or just logically disabled (Axis.DriveEnableStatus=0?) I think that a technote should be written that explains most of this and maybe even has a some sample code that could be used. -Paul [/INST] I guess this is like a self help forum.

<s>[INST] 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 [/INST] 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 </s> |
<s>[INST] Driven Unwind for Web Tension Control Summary: Please recommend a motor / drive combination Hi, I am trying to pick out a motor / drive combination to handle a driven unwind on a piece of web handling equipment. This unwind will feed a spool of web through a series of rollers that guide it through a machine for processing. One of these rollers acts as a tension load cell. The tension load cell provides a signal that corresponds to actual web tension to an automatic tension controller. The automatic tension controller allows the operator to enter a tension set point and uses a PID control loop to regulate a -10 to +10 VDC control signal that can be used to regulate tension. The automatic tension controller manufacturer recommended that I use a permanent magnet DC motor for my Unwind Shaft with a 4 quadrant regenerative DC drive board. Wiring the -10 to +10 VDC signal from the tension controller into the drive board would allow the tension controller to maintain tension at set point by controlling the motor speed. They say that this is a common use of their tension controllers and it works great. I ran into some confusion though when I started thinking about what motor to use. My requirements are such that my line speed can be anywhere between 1 - 25 feet per minute (25:1 speed ratio). This unwind can accommodate spools of material anywhere between 3-1/2 to 18 diameter (5.14:1 diameter ratio). The way I see it, this means that the required speed ratio for my unwind shaft is 128.5:1. After speaking to a few of my suppliers, I think that this speed ratio is too much to ask from a permanent magnet DC motor. I have been told that the typical constant torque speed range for a permanent magnet DC motor is 60:1. (Please correct me if this is wrong, or if you think I might be able to find a DC motor with a greater speed range). Yesterday, I was advised by someone that my best best was to first pick out a motor that meets my 128.5:1 speed range requirement. He said this would most likely be some sort of AC vector motor. After choosing my motor, I would then have to find a drive that not only support this speed range but that also could follow the -10 to +10 VDC signal from the tension controller. He suggested that I should look for some type of AC Inverter drive and that it would need to have regenerative capabilities. He mentioned that I would probably need a drive that can make use of encoder feedback, although I don't fully understand this suggestion because I am trying to do closed loop tension control rather than speed control. Although I am controlling tension by controlling speed, I don't care or need to know what the actual speed is. I just want the drive to do what the tension controller tells it to. Based on the recommendations of the tension controller manufacturer, the motor power that I would be looking for would be 1/4 HP. If anyone here can recommend a motor and drive that might suit my needs, I would really appreciate it. Thanks in advance, Paul [/INST] Take a look at the new PowerFlex 525 drives. Your application is extremely small and the AC drive/motor will offer excellent speed control (even though you're controlling tension). We use the PowerFlex drives in many web applications but much larger (150HP and up). You can use the DriveLogix inside the drive to fine-tune the loop, which essentially is what you have. On a small scale you're talking about, a drive on the unwind stand running slower should suffice without having to look to regenerative drives. Can't completely spec a motor but a small inverter-duty motor will work fine. I typically upsize the unwind stand drive to accomodate for any heat generated by the drive. \\n </s> |
<s>[INST] Usage of Drive Logic Command Bits over comm link? Hi, I am going to be using a PowerFlex 70 Enhanced Control drive for the first time. I ordered this with a 20-COMM-E Ethernet/IP to DPI Comm Adaptor. I will be using a ControlLogix PLC with a 1756-ENBT Ethernet/IP module. I'd like this CLX PLC to be completely in control of the drive - I want the CLX to issue all start / stop commands and to send the speed reference (setpoint) over Ethernet/IP. I also want the CLX PLC to be able to read the actual speed over Ethernet/IP. I am looking at the 20-COMM-E Ethernet/IP Adapter User Manual. Chapter 5 Using the I/O (page 5-11 figure 5-3 to be exact) shows an example ladder logic program that uses the Add-On Profile for to manipulate the drive logic command bits (Start / Stop / etc) in the drive. What I don't see here is an explanation of the proper usage of these bits. For example, I am guessing that Start/Stop logic would work like this: In order for the drive to be able to run, you have to keep the _Stop bit energized at all times. When the _Stop bit is energized, momentarily energizing the _Start bit will start the drive. While the drive is running, momentarily de-energizing the _Stop bit will stop the drive. ...I think this is probably how these bits work, but can anyone tell me if there is anything I should read that explains the proper usage of not only the _Start and _Stop bits, but also the less obvious logic command bits such as _LocalContrl, _SpeedRefID0, _SpeedRefID1, _SpeedRefID2, _MOPInc, _MOPDec. Do these bits function exactly as if you had configured a physical digital input (Digital Input 1-6) for the corresponding function of the bit? Any help will be greatly appreciated. Thanks in advance,Paul [/INST] Hi Paul, your assumptions aren't correct... :smileysurprised: The following is reguarding the Stop bit (bit 0) inside the Logic/Command word: A “0 = Not Stop” condition (logic 0) must first be present before a “1 = Start” condition on bit 1 will start the drive.The Start command acts as a momentary Start command. A “1” will start the drive, but returning to “0” will not stop the drive.In order to Stop the drive you'll need a logic 1 inside bit 0 of Logic/Command word. I suggest to review App.D of the Adapter User Manual to understand the Logic/Command word bits and how operate them; the same for the Status word.

<s>[INST] 1398-PDM-75 + F-6100 motor bad problem at aux. circuits reset (rare but happening) Summary: 1398-PDM-75 sometimes makes F-6100 motor running away at auxiliary circuits resetI've done many applications since 1998 with 1398-PDM-75 + F-6100 brushless motors. Never had big issues except in an application where, in the last year is starting to happen that sometimes with no evident reason, just after auxiliary circuits reset the brushless axis runs away for a while that it stops with no drive error and everything ready. No errors logged inside the Ultra drive. Everything appears normal. Sw is standard and I've done many. Even changing 1398-PDM-75 with another one generates same reasults. Same after have changed F-6100 motor. Changed contactor, filter, encoder cable with no results. Of course, all hardwar checks have benn done and re-done more times withous find any probs. Firmware used in 1398 is 3.23 as is in at least other 30 application I've developed during last 13/14 years with this exact product. It's a rare event but it continues to happen only on that particular mahcine. Any idea or suggestion is very well appreciated [/INST] nan \\n </s> |

<s>[INST] Kientix 5700 Feedback Integrity Loss I have a system that has several Kientix 5700 servos responsible for row forming for a palatizing system.
