  1. Problem with Stepper Drive

    PLC : Mitsubishi FX5UJ-60MT/ES Stepper Drive : TROY TR22-2   My problem is, When I Jog it, the Motor will have noise and vibrate(Example at video). I already ask my supplier and they test with their kit, my supplier says suspect the speed may not enough faster, so will have this noise. But when I use PLC to trigger it, still have the same problem. Even I increase the speed, the motor still rotates the same as the video.   i changed PLC to Omron  CP2E PLC, don't have this kind of issue.    Please help me,Thank you WhatsApp Video 2023-05-25 at 12.53.32.mp4
  2. Motion Control Help

    Hi Guys, I may need some help on how to program the stepper motors by using  FX5UJ PLC. This is my first time using it, not too familiar with Mitsubishi PLC. Anyone can share me sample program for reference? I have no clue what command needs to use. I only have experience in Omron Sysmac Studio programming servo using Ethercat. Other than that I can say I'm a new guy in PLC.   Thank you very much for helping me.
  3. Hello, I am having an issue with a PowerFlex 700S. This drive controls a travel motor for an overhead hoist. It is periodically not starting after stopping at a programmed point and sometimes stops while traveling to the next station. It does not give any faults or alarms. It is controlled remotely from a CompactLogix through a wireless router to an N-Tron unmanaged switch to the 20-COMM-E adapter. There are some limited manual controls, but the normal operation is a start, stop and speeds all sent from the controller. We have the DI6 set to enable and that does not seem to ever be lost. When this happens the only thing that I can find is the start inhibit parameter shows a bit 8 set high which is a start request present. I can see the PLC has already sent the start signal. I can put the machine in manual mode then cycle back to auto and the drive takes off. The only thing I can see changing while doing this is the start command is dropped and then sent again. I have changed the comm adapter as originally I had thought this was an issue with comms, but now I am skeptical as I have it set to fault and stop if a comms loss is detected. I am also able to connect to this drive and others on the same hoist through the wireless comms, so I feel better about the comms path. What causes this start inhibit bit 8 to become active? Does this seem to be a communication issue or a potentially a bad drive?
  4. Servo drive control power

    Hi, I have a servo coil feeder. It has HMI, PLC, MR-JE-100A Servo drive, and motor.  Recently,  smoke came out of drive. One capacitor was almost split. 400 V, 680 uF. This is right after 3-P rectifier. I believe there was some sort of over voltage. I found the capacitor from China,  and installed. HMI and PLC are sending power and signals, but no sign of activity at the drive. DC bus is alive, but can't pass beyond relay after bridge rectifier. There is no power at control circuit either. No service manual. I ordered another same drive. Do I need to set anything on the drive, or HMI and PLC has all the necessary signal to drive the motor? NC+servo+Roll+Feeder+manual (2).pdf
  5. Can anyone tell me how to check fault history in Allen Bradley powerflex 40 drive?  
  6. Hello Experts We have a machine with Mitsubishi Servo MR-JE-2008 With PLC Fx 5U & HMI GS2107 Yesterday we altered PLC by adding a row with input and timer & used this Input in next rung for weld start Although we did not  find any linkage but found "'Screen error Ok"' on HMI and after pressing Ok, HMI screen getting blank. We restored original PLC backup - PLC in Run Mode still ""Screen error Ok"" on HMI Via GT designer 3, we have loaded HMI backup, now HMI screen is OK and normal Getting Ab on Mitsubishi drive - we feel it is not an error but due to this we are unable to rotate motor although other functions like door open/close etc Ok In PLC, online mode, we are finding Servo in ON but unable to understand Ab on Drive and may be due to this, unable to rotate motor Please refer to attached HMI, PLC & Servo Backup Request advice HMI BACK UP.GTX PLC BACKUP.gx3 Flange Welding_Tag Line Servo Backup.mrc2
  7. Motion Control

    Hi Everyone.   I have been tasked with changing out an older Flex Drive servo drive to a more modern Micro Flex drive in a machine that has an Omron CQM1H-CPU51 PLC.  I'm having a few issues but hope that i can gain some clarity around at least one of the hurdles Im facing from here. Biggest issue for me at this moment is My work hasn't yet purchased a programming lead for this PLC (or even the bits required to make one myself) but i have a feeling the control for the Servo is done via motion control in the PLC.  Question here is, if changing from one servo drive to another type, will the motion control code need to be updated to work with the new servo drive?  I have very limited experience with motion control itself at this stage so I'm a bit lost when it comes to these sort of details. Regards Kiwi_man82
  8. question about ABB ACS800 control

    I am not a drive person (far from it...),  but I am working on a project using a number of ACS800 drives.  On one drive (only seeing this issue on one drive,  as far as I can determine) - when I specify a target speed and also specify maximum acceleration - there is a (significant) difference in terms of the accel time whether I have the drive set to internal speed control vs. external (encoder) control.  It takes almost exactly twice as long to get up to speed when set to external vs. internal.  (And problem with keeping it set to internal is that we lose accuracy at higher speeds,  and also at very low speeds...).  The most obvious issue would be a bad or improperly set encoder module,  but speed of motor is correct (as measured by tach) whether using internal or external.  Encoder module was also swapped for new one,  with no difference.   The only parameter that I am changing is speed by external encoder vs. internal  (I think that it is parameter 98.01).  Would anyone have any idea as to what could be causing this?   Thanks for any ideas!
  9. Hello all,    I have 3 kinetix 5500 drives connected in series but some how the 3rd drive lost power. all the fuses in the cabinet look good. nothing else is tripped either.    any advice is appreciated.  thank you   
  10. Hello All, I'm a newbie to Omron programing  I have a program where I want to control a stepper motor with 1 plc output "pulse output0"  in my program I used PLS2 instruction but when I execute the instruction the motor won't rotate and the plc outputs are off, My wiring is fine, and my plc is CP1E-N40S1DR-A MY 1st output is pulse output 0 Q100.0 and also the driver wiring with the stepper motor is good ( I did a test with siemens plc the motor does work fine ) , what could be the problem? thanks, PLC OUPUT 0 SETTING

  12. Hello everyone    I am working on modbus TCP protocols to communicate between SEW drive and Omron PLC CP1L-EM. I am following modbus TCP function block from Omron, But i have updated that block because of is not fit to SEW modbus communication. Currently, I am sending a control work to SEW but I am getting error on Modbus TCP from SEW drive, which is invalid data. So I am looking your help is you work with SEW drive before and communicate over modbus, then please let me know how to make a data string for read and write (SEW Drive function 23). I am using 3PD data structure.    Thank you
  13. Dear forumers, It started on ISPsoft end nov. 2021. I have to program a MS300 drive. It is a very interesting software. And even if it is a bit rigid, in ladder for example, I begin to like it. I would need some help though, especially on the APIs properties. Indeed, the F1 help doesn't work well. Sometimes it doesn't open (can bypass), sometimes the APIs I’m looking for is not in it.  In the different pdf's I have gathered, the APIs, especially those concerning the MS300 variator, are not all explained. Does anyone have precise literature, official or personal, on these APIs?  It is difficult to program by having to guess/test. The doc. I currently have: Delta Standard Compact Drive MS300 Series User Manual (2 PDF : one with 688 pages, one with 510) 2 Quick guid, probably done by my seller (Word format) ISPSoft User Manueal (2 PDF : 2017/06/14 with 840 pages; 2021/03/29 with 1160 pages) A few DVP PLC PDF : DVP-28SS2; SA2; SS2… I also had trouble installing the last 2 versions of ISPsoft on a Windows 7 pro 64 bits PC. The V3-14-0 version refused to install, displaying an inability to write to a temporary folder. The V3-13 version (SW_20210420) just froze during installation. No info. I didn't look further (the client is coming netxt week), I stayed at 3.12.01 (beta) Has anyone ever had this? I will try insall V3-14 on a windows 10, and also try a monitored install on my one personal PC at home with w7 pro 64b. Thank you in advance to anyone who can help me. I have contacted DELTA support in Europe and am waiting for answers. As well as my seller, who has technical competence, has already used this software, but is far from having answered all my questions. Best regards, KsioP  
  14. Hello, I wonder who can help me out here. I am new to the CX programmer. I want to communicate to selema drive through CX programmer. The drive is IPS plus Selema. The company was gone in 2017. There is no manuals regards to the drive. Here is the issue, in the program. The SPED block show port specifier is 10, the INI blcok show Port specifier is 0. Refer to the PLC picture, my first questions which one is port 10? I think port 0 is the left bottom cable from the second picture. So port 10 is the last module?  Second, Do anyone have manual or knowledge with the selema drive? Is there another one to communicate with the drive not using CX programmer?   thanks
  15. Anyone know what could be missing to be able to import this stepper motor to sysmac? This is one of the supplied xml files for the stepper motor.     FASTECH_Ezi-SERVO2_EtherCAT - OMRON.xml
  16. HELLO EVERYONE THERE IS THIS PROJECT WHERE I CHANGED THE OLD SERVO SETUP WITH NEW SERVO DRIVE MRJ4200A-RJ SERIES. OLD SERVO HAS A REVOLUTION OF 15 BITS BUT NEW SERVO HAS 22 BITS RESOLUTION. PROGRAMMING IS SAME BUT MY DISTANCE CALCULATION IS DIFFERENT NOW AND MACHINE DOES NOT GIVE CORRECT DISTANCE. PLEASE HELP ME
  17. I'm sure many of you are in the same boat with supply issues and elongating lead times with the Logix 5500 and 5700 servo drives. Are there any decent alternatives that are easily integrated into a 5380 controlled system, maybe with an AOI? I've looked at Beckoff and Parker systems, but Parker only seem to line CoDeSys as far as I can tell. Do any of you clever clogs have any suggestions for a well stocked alternative? As a side note, I'm not new to PLC programming, but I am only 6 months in to using motion and servo systems so be kind :)
  18. Hi,  Can someon help me with the following question. Like what makes a Kinetix 6000 drive a Guarded drive ? What type of safety stuff can you set to make it more safe.  Is it some parameter ? I am bit confused, by the manual. Should I active it in the PLC program or how ? Or it is some setting like a safe speed or torque.  I would really appreciate any help. Thank you so much ahead.  Have a great day, thanks for the reading.
  19. 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    
  20. hello dear team, im trying to make a back up for some FR-E700 with the FR CONFIGURATOR SW3 but when i start the communication with the USB cable the software cant recognize any port by the way im using windows 10 in my laptop and when i check the devices administrator it doesnt shows in USB ports the drive info just in other devices and in details shows: "USB device was not migrated" does anyone know what can i do?
  21. 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.
  22. HSPsO

    I am using fatek FBs 32MN PLC. i need to run the nema stepper motor synchronized with induction motor's speed with some ratio. in my case the speed of stepper motor will change as the speed of induction motor changes its speed, may be many times in a second. Problem is that the speed of stepper will be constant as before until i have to disable and then enable again HSPSO function. is there any solution that i can dynamically change the speed of stepper without disable and enable HSPSO function ?
  23. PLC Panasonic FP0R Motion Control

    Hi, I am using FP0R C32T, i use FPWIN GR to make plc program using jog operation instructions F172. I used the program exactly like manual, but still got error code 45? Did anyone know about this thing?
  24. Hello guys, I am very new at this. I am trying to make a Schneider PLC (TM251MESE) to send some serial commands (485)  to a integrated stepper motor from Automation Direct (STR-MTRD-17030RE, but I am lost. The driver has been program to receive the SCL commands. But not quite sure how to send those from the plc. Im using SoMachine V 4.2 Have any of you done anything similar? Any example will be greatly appreciated.  Thanks
