  1. 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? 
  2. 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  
  3. 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.

  7. 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 
  8. 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
  9. 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.
  10. 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    
  11. 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.
  12. 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.
  13. 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? 
  14. Hi all, I am studying how to control servo with PLC Mitsubishi Q-series. When I click Servo_parameter in Simple motion module setting tool, this annoucement appears.  Does anyone know why it appears? I tried reinstalling MR-configurator 2 but it didn't help. Please give me some advices. Thank you all!
  15. 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?
  16. Is it possible to reset " Motor replacement detected error" ( Error code 95.01) using code without connecting to PLC through sysmac studio? If yes please suggest how to do it... Thanks in advance...
  17. Is there a way to monitor the Temperature of a Servo Motor on Allen Bradley Servo motors... MPL? PLC: CompactLogix 1769-L30ERM Drive: Kinetix 6500   Motors: MPL-B310P-MJ72AA, and  MPL-B560F-MJ72AA I would like to be able to monitor the temperature, and flash a warning screen on the HMI if the Motor gets too hot, or perhaps shut down the operation before the Motor overload trips. The drive and PLC are connected through Ethernet IP What I don’t know is if that Motor heatsink temperature information is available to the PLC.
  18. Virtaul Axis - Simulation

    Is it possible to simulate a servo axis in Sysmac Studio? Can you create a virtual axis and then set velocity & position for this virtual axis? If this is possible, is there an example program that anyone can share with me? Thank you. Happy new Year! 
  19. Getting this error while adding MC_TorqueControl. I want to control torque from HMI value. Using R88D-1SN08H-ECT drive and R88M-1M75030T-S2 Ac servo motor with NX1P2 PLC. Newbie Here. Please support. Error    1    The Axis parameter of the MC_TorqueControl instruction does not support single-axis position control axes.    Program1 Section0    Row 6  
  20. Hello,   I have  a project where I need to run 2 Omron Servos 1S at same time with 1:1 ratio. I created virtual servo axis and attached my 2 physical axis to virtual one ( screenshot from Sysmac studio attached). For some reason when 1 of the axis has a fault, my whole virtual axis goes down. For recovery I need to to do GearOut and GearIn again. In one of the moments I'm losing count in my motion that cause issue later. I believe that I'm doing something wrong.  Can somebody help me to understand how I can keep my synchronized axis all the time? Thank you in advance!  
  21. MR-J4-60GF-RJ Programming

    I am new to Mitsubishi (only done Allen Bradley) and Im tasked with programming a MR-J4-60GF-RJ servo drive with a HG-SR motor. I am using GX Works 3 and have a R02CPU and I am wanting to use CC Link IE Field Basic communication with this. Do I have to use the point table to move this motor from "Point A-B" or can I send absolute positions, speed, etc to a given position. Any advice/programming examples would be great. 
  22. Autotuning Kinetix 350

    Hell PLC World! I have been trying for several weeks in my spare time at work to tune an Allen Bradley Servo Motor.  Below is the list of hardware I am currently using: - CompactLogix Motion Controller (1780-L33ERM) - Kinetix 350 Driver (2097-V34PR5-LM) - MPL Series Rotary Servo Motor (MPL-B310P-MJ74AA) I have been using RSLogix5000 for testing and I plan to use it to develop a simple conveyor type program later.  I have tried a list of things which will be below, but to no avail, I cannot simply jog the motor for any period of time without triggering a position, velocity or bus voltage error.  I have tried changing the motor, driver and feedback cable to no avail.  Here is the process I have used: 1) Add the hardware to RSLogix5000 (PLC, Driver and Motor) 2) Configure the motor 3) Run the hookup test.  This works flawlessly.  The motor will slowly turn independently on the feedback test for as many revolutions as I input.  This is what makes me think I am doing something wrong in the tuning process. 4) Run autotune process with the velocity, acceleration and jerk set well below the limits of the hardware.   5) Attempt manually control motion 6) Recieve error I have tried changing the input from trapezoidal to S-Curve, changed velocity and position limits, manually tuned velocity gains in a myriad of configurations.  I have swapped legs on the 3 phase input (which made matters worse). I suppose it is possible that multiple pieces of hardware are faulty because this equipment was previously used, but I still cannot wrap my head around why the hookup test would work so flawlessly, yet I cannot just get the servo to rotate at an equivalently low speed. If anyone recognizes my mistake, I would be eternally grateful.  I am an intern studying control systems in graduate school and as popular as AB is, I would sure like to get some experience with it.  Thanks in advance!  
  23. Hello, I have a project where I need to synchronize 2 servos. I use GearIn command to sync this servos. I created 1 virtual axis and attached my 2 physical servos to virtual one. Based on application logic I need to stop sync servos when count from sensor reached max value. To stop the servos I'm using ImmidiateStop command. For some reason stop point for this servos variate based on servos speed.    How I can improve my stop point?      Thanks!
