  1. servo auto tuning

    Hello Guys! I have couple of questions about tuning an ab servo motor. -Actually what does the drive or plc doing when I launch a servo auto tuning?  - What are the little boxes like position error integrator ? There are checkmarks in fornt of the lines. Can I choose the methode or something? I mean its not "auto" ? Why it is auto then ? - Can someone send me some basic literature where they explain me what these stuff acutally meaning ?  - What is the hook up test what for is good ?  -When you are doing a servo auto tune what are the parameters that you are monitoring and why ?  -I should do the auto without or with load ? Whats the difference ? I know there are so many question I would be so grateful if someone could help me with these answears, or even just with one. Thanks again. 
  2. Servo safety

    Hi. I would like to ask that like you guys are when using a kinetix servo motor what type of safety conditions are possible ? I found a fault actions label. Is there anything else like between the parameters or so ? Thanks ahead. 
  3. Good morning guys,  in your experience what is the best way to syncrhonize a motor controlled in speed with an inverter and a motor controlled in position with a servo drive? Let me explaine better what is my situation: I have a belt running normally at a certain constant speed. in some moments, I would like to syncrhonize the speed according to an axis controlled from a servo. the command of a servo specific position target and of course speed and acceleration e deceleration rate. I would like to adjust the belt speed in way to follow as accurately as possible the servo movement. Thanks a lot Andrea    
  4. NX1P2 Motion Control

    Hi:       I need to change an old PLC  with NX1p2  to control 3 servo motor by means of Analog Outputs couple with encoders, My job is to change the PLC only. So the servo drives and drivers are untouchable (No budget and involve too much mechanical works).   I observed that Sysmac Sttudio Axes setting has this: Servo Axes, Encoder axes, Virtual Servo Axis and Virtual Encoder Axes.   I believe the Encoder Axes couple with Analog Output is able to to do the Job? If so, what function block should i use? If no, do any body have a suggestion of any function block i can use? Thanks  
  5. We currently have Delta DVP60ES2 and DVP32ES3 PLC's doing positioning control on Inovance IS 620PS2R8I 400w Servo Drives by Pulse/Direction. Under both of these environments our pulse count read on the Inovance drives are reading higher than what the PLC is outputting. We also have Mitsubishi & Inovance PLCs, which when connected to the same Inovance drives dont have any discrepancies in the pulse count. We also have Delta ASDA servo drives, which when connected to the Delta DVP PLC's also don't have any discrepancies. Given we have tested these combinations, it has led us to believe there is something unique about the pulse train output from the DVP PLC's that is causing the Inovance drives to read additional pulses. Has anyone experinced a similar issue with Delta PLC pulse output? If so what was the solution?

    Hello I am trying to communicate a CJ1M with a CJ1W-EIP21 Card, with a Logix Control, but I have not been successful, what I am looking for is to read data, from the OMRON and see it in the Logix Control, but I have not been able to establish communication, I am looking for someone You will already have a functional example, with the backups of both PLC'S, to be able to observe how they made the configuration. Thank you for your support Greetings
  7. Kinetix 6000 Overspeed Faults

    Hi all, I'm having an issue with one of the Kinetix6000 allen bradley servo drives on a filling line that I support. This particular servo motors controls the rotary movements of a series of pumps to ensure accurate dose timing. Every time that I start up the machine, the PLC (Controllogix L7 firmware v28) executes a homing sequence to ensure the servo finds its 0 point. However, the servo in question keeps getting an 'Overspeed Fault' (E55). So far in troubleshooting, we've basically changed every component. We replaced the drive, feedback cable to the drive, and even hooked up a new free-spinning motor directly to the drive. Every component change has resulted in the same Overspeed error shortly after the homing sequence starts. To try and rule out a mechanical issue, I even disabled the homing sequence in the PLC and tried to move the motor using Motion Direct Commands. Immediately after a MSO command, the drive faults out for OverSpeed even with no motion. The last bit of troubleshooting we swapped the position of two of the drives, but the same OverSpeed fault happened on the drive connected to the rotary movement motor. At this point, I'm even considering changing the sercos fibers and the Kinetix power rack. Has anyone experienced anything like this before, or have advice on what to try to make it work? Thanks in advance for all your help  
  8. I'm having trouble with some Powerflex 525 drives. Right now what I need to do is run them manually from the keypad to test conveyor belts.  Is there a way to do this and if so how?   Thanks in advance.
  9. So I'm new to the automation scene and in my training I decided to setup a little test rig, plc, drive, servo, sensor, hmi...etc.  Everything is wired and hooked up. What I'm trying to do is simply get the servo to spin. here is a screenshot showing what I have. I think there are some flags on the servo itself that need to be set but I'm not sure how to do that. In Base(x) I have tried 0, 1, 4, 5, 35. Any help would be appreciated.

  13. QD75M4 AND MR-J2S-40B

    Hello i have problem about connection between QD75M4 AND MR-J2S-40B  now MR-j2S is display "Ab" every time i can't solve this problem 
  14. I am looking for how others have set up vertical axis motions using the Kinetix 5700 servo system. I have a 2 axis pick/place unit with a horizontal axis (X @ 2500mm) and vertical axis (Z @ 1200mm) that works as designed during normal operation. X axis has no holding brake and Z axis has a factory installed 24vdc to unlock brake. There is a GuardLogix L81ES control system that handles the safety and control. On pressing E-stop/opening Gates the vertical axis will stop the motion, apply the brake and hold with no problems. (2198-D032-ERS3 Drive, 2198-P031 Bus Power, MPL-B430P-MJ72AA X Axis, MPL-B330P-MJ74AA Z axis) The issue that I ran into was an accidental download of the program without activating the e-stop and the vertical axis dropped unexpectedly when entering program mode on the processor. I am aware that this instance was my fault as the programmer, however I am also concerned that this might occur again in the future if the controller ever enters fault mode or someone else completes a download. I have done some investigation with the "ProgrammedStopMode" parameter on this single motion axis and attempted all 5 options and the vertical axis still has a free fall drop for a second before the brake grabs hold - so evidently this is not working for me. (Page 24 of Vertical Load/Holding Brake manual - https://literature.rockwellautomatio...t003_-en-p.pdf) I am curious if there needs to be something done elsewhere as the X and Z axis are set up as coordinated axis? I also am unaware if I need to preform some action/parameter with the bus power supply for this? The current state of the machine as it sits now is preforming a MSF in manual mode after 5 seconds of inactivity or 30 seconds in auto mode. This axis is usually in demand every ~22 seconds. This will shut down the axis after preforming a brake test on the vertical load and seems to function OK, however it is still in the back of my mind the issues mentioned previously if we ever enter a controller fault while indexing. Thanks for your insight
  15. I searched FX5 manuals and it appears that with the high speed inputs I can run a stepper motor without a motor controller. I have little experience setting up a new system with any motor but have made changes with servo issues. I sent a request for info from my supplier but I still have some questions/requests.   1. Can an FX5U control stepper motors without a motor controller? 2. If not then what Q/R series setup is required 3. Are there any document to help understand? (program examples are welcome)   Main objective is to run a sensor head to 3 or 4 specific points using a belt driven linear actuator with a nema motor.
  16. Hello Everyone. We have Schneider TM241 PLC Along with Citect SCADA System at 100MWp Solar Power Plant to monitor and control various equipments like Inverters, Switch-Yard, MFMs, Weather Monitoring Systems etc... Government Authority here asked every solar plant to control the generation as per the instructions by Load Dispatch Center, for that we need to implement logic to control Generation as per requirement. For that we are controlling generation from inverters by giving them generation setpoints calculated by PLC using PID function.   But we are facing one problem while using PID. (FB_PID of Toolbox Library)   Suppose we need to generate only 60MW out of 100MW. So we set PID setpoint to 60MW and according to that we get PID output and according to that PID output value we provide generation setpoint to every inverters.   This system works very fine until the clouds comes into the picture.   Now suppose Setpoint of PID is 60MW and PV is also near about 60MW, and suddenly large cloud comes over plant and block solar radiation.   In this case generation comes down to 10MWp(or any value below 60MW), So output of PID will Increase and keep increasing and settle at the Maximum value. but without solar radiation generation value stays very down then Setpoint.   Now suddenly Cloud moves and again solar radiation increase, but the PID output is maximum at that time so, Suddenly Generation goes from 10MW to near about maximum capacity (100MW) instead of 60MW, and then it will slowly comes down to 60MW.   We need to rectify this generation shoot up when cloud moves. Anyone have idea how can we solve this problem or anyone have programmed PID in this kind of situation.   Is there any function block available to do this correctly like function block of PID with two Reference or something like that...   We are using TM241 which is CoDeSys based PLC.
  17. Hello everyone, I have a Kinetix 6000 CIP drive (unwind) and I need to control its speed by a PID controller. I have everything working except the MCD instruction doesn't pick up on the PID output value change. It changes the JOG speed, which I use to control the unwind, if I set the speed manually, which is slow. The PID changes the speed almost continuously. Any suggestions are welcome. This is how I'm attempting to control the speed: A1_r_JogSpeed = PID output value   Thank you    
  18. Hello to everyone! Our company is trying to make a quick disconnect for motors that connect tp servo amplifier R88ND-1S. As I know Omron doesn't have any options to do it or make an extension cable. Does anyone tried to cut the cable and make custom connector? If yes, could you share your experience? I'm afraid of having issue with encoder count. Thank you in advance! Scotty.
  19. Hi all! We have a problem with a Mitsubishi system. After switch off the machine in home position and back on, it resets the servo encoder value to 0.  I checked the servo parameters, and the Absolute encoder is enabled, the ext. battery is ok and no zero reseting in the program ( I think...). Is there a parameter I should check or some setting in the intelligent module? The system consists Q01CPU, QD77MS2 im., J4 200B amp with 6v battery, and HG-SR152 motor.
  20. Constant Web Tension Control

    So I'm having trouble writing a FBD within my current program for a slitting line. I need to keep a constant tension on my web as it is being recoiled onto our recoiler. I wrote a simple program using a sensor to read the growing rate of the coil to get a radius and I have feedback on my torque on the recoiler motor. The simplest math for this application without getting into anything too fancy should be Tension(lbs)= Torque(ftlbs)/coil radius. only problem is when its less than a foot then my calculation is thrown off and it actually shows tension goes up until it reaches the one foot mark then it seems to scale correctly. Do I need to scale something else? Any help on this would be appreciated.
  21. Dear all, I had bought a mitsubishi plc fx3s-20MT/ESS which is the source output and I plan to try to send pulse to Mrj3a Servo Drive. According to the manual, it stated that the servo drive able to support the source type plc but I do find out that manual also mention that only sink type plc is suitable for melsec servo drive.  Anyone can help me in this case? 
  22. Can someone please suggest a Control Panel Builder that is located in Germany?   I work for a company in Australia and due to Covid 19, we are struggling to meet an onsite date for a project in Germany.   This project uses Siemens PLC gear, Danfoss drives, and mostly Schneider electrical gear. The enclosures are custom and stainless steal.    I have electrical schematics and enclosure drawings for quoting.
  23. Hi all, I am studying how to control servo with PLC Mitsubishi Q-series.

Please give me some advices. Thank you all!
  24. I have a Mitsubishi FX5U-32M with 3 MR-JE-40C servos. Our system will be used in a robot cell, and needs to convey some information to the customers system, which is this EtherCAT side of things. They want to know RPM, torque values, position ,etc, of things on our system.. Our Mitsubishi supplier recommended an AnyBus X-Gateway (AB7961). They have a few YouTube videos on configurations, but unfortunately none on the Mitsubishi side i found. I've only been using Mitsubishi for a little over a year, but know my way around GX Works 3 pretty well.  I come from the Rockwell world with EDS Files and tag based setups, and for the life of me cant figure out where to start with this AnyBus. I've gone to the support page, got all the downloads and software, and gotten online with the Anybus. As far as beginning to setup the Anybus in GX Works side, to setup what registers i want to send, im lost... Anyone out there have experience with this sort of thing?
