  1. Dear Team,   We are looking for a suggestion to drive a motor which is away about 2100 Meter from its starter. The Pump is located in a pond in the forest which is 2000 Meters away from the nearest building. The pump capacity is 55kW and we are considering 55kW HD VFD as a starter. As we see the distance is much higher we are looking for you valuable suggestion about how this thing is gonna work without any abnormalities.
  2. Hi everyone , I need your help !!! I am currently working on a project where I have to control a stepper motor (oriental motor AZD CEP) with a proface HMI. To do this I use implicit Ethernet IP messaging. The problem is this: when I change screens, I lose the connection between the two devices. After 20-30 seconds, the connection is reestablished. I've already spent two days on it and I can't figure out where the problem is coming from. Does anyone have any idea what's wrong? If you need additional information or screenshots to understand, let me know. Thank you in advance for your help.
  3. I'm using a Mitsubishi FX5UC PLC to control some Minas A6S servo drivers. Previously I've always used a pulse train and discrete IO (it's the way things have always been done here). This time I'd like to use Modbus RTU over RS-485. I'm pretty confident that the RS-485 wiring is correct because I'm getting an exception code back from the driver rather than the messages from the PLC timing out.   I've been reading the manual called Operating Instructions (Overall) for the MINAS A6 series, particularly the communications supplement. I may be misunderstanding this, but the Modbus implementation appears to be non-standard. Specifically, in Schneider-standard Modbus, after the slave ID (or in this case, axis ID), the next part of the message is a function code that specifies the type of command; 01h is to read a coil, 05h is to write to a coil, and so forth. Whereas the Panasonic manual describes a different list of commands - to read the driver serial number it would be command 0, mode A, which gets transmitted as A0h. Documentation screenshots are attached.   The PLC function ADPRW only works with standard Modbus commands. So what I'm wondering is, am I misunderstanding the communications supplement, or do I need some code specifically for these drivers? If the latter, I would assume that someone has already written a function block or a predefined protocol definition for this hardware. Does one of you fine people have one?   Thank you in advance for the help!
  4. Hi  I want to adjust servo motor but I cant .After finishing the tuning error C004 is displayed
  5. 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
  6. Hi Guys,  It might be an off topic, but I need some help, with motor sizing. I have to choose a Sew motor with a proper gearhead. I made the calculation, for the speed thats okay. But I got stuck with the loads. It will be a conveyor, the roller and the product mass altogether is 29 kg. I  made the calculation for the load inertia check: Roller moment of inertia (J1);    m2=mass of roller;     d=diameter(mm) J1=1/8*m2*d^2*2=1/8*8*0,2^2*2= 800 * 10^-4 kgm^2 Belt and material mass = m1 = 21 kg;  Belt and work moment of inertia (J2): J2=m1*( π * d)^2/4* π ^2= 2100 * 10^-4 kgm^2 J=J1+J2 = 2900 * 10^-4 kgm^2 They give me a motor with gearhead, sew eurodrive Ka37/T DRS71S4BE05. This motor performance is 0,37kW, I think its enough, but on the documentetion, I didn't find any data, about the permitted load inertia. Can anybody help me with this ? Thanks ahead.            
  7. Does anyone know how to change the reading on Omron servo motor reading from negative to positive? The encoder is reading negative values when it is moving in the forward direction.  I am using 1S servo on NX1P2 controller on Sysmac studio software.  Please suggest. 
  8. Does any one know any instruction that rotate the 1S Servo Motor continuously with angle(0 to 360)  and velocity control ? https://forums.mrplc.com/index.php?/topic/35459-omron-g5-servo-drive-rotary-mode/#comment-165564   Above link may be quite close to what i want. But I have no idea how to set it up   Simon        
  9. MR-J2S- Servo Driver to PLC

    I have a test station to test MR-J2S Servo drivers,  I am looking for something unique in the drivers to be able to save data about that test.  First thought was the SN, but i am not seeing any way to pull serial number from the driver. Only found it on the side of driver and really don't want people having to type it in , cause usually they type in the wrong numbers.  Does anyone know of a way to get the serial number out of the driver? or at least where it could be found?  Or any other unique identifier in these drivers?  
  10. How can i limit MRJ4 servo load?

    Hello, I am beginner at servo and its driver. i am using MRJ4A driver and HG SR102 servo motor. i want to make my servo stop or alarm when the load is over the maximum load that i set by my self. what parameter should i set to limiting servo load even if the servo motor strength enough to lift the load.?  
  11. 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
  12. QD77GF Error D304

    Hi. I am using PLC Q06UDV wit QD77GF to operate 11 servos, it is my first time using QD77GF and CC-Link IE Field. I've done the parameter setting. but the qd77gf error lamp started to blinking. i try to check it in cc link ie field diagnostic and didn't find anything except the error lamp blinking in monitor view. then i checked system diagnostic , no error showing up but, only historical error when i started the power of plc. it show D304 error.  in manual book the solution are lengthen the operation cycle qd77gf, check the cable, and shorten plc scan time. where can i find this setting sir?  
  13. Hello I am not sure if anyone know how to select cable cross section for 5KW AC motor? Thank you
  14. 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   
  15. Hi everyone,  I am new to Mitsubishi PLC. I am trying to see from where Run or speed commands goes to Servo. I have MELSEC FX2M-32MT with FX2N-1PG cards for the Servo and I am using GX Developer 8.91v  Also, I would like to mention that initially I found out that BATT V light was lit so here what I didi. >I replaced the battery within 20 second while powered ON. Before changing the battery I took upload of the program successfully.  >I have cleared PLC memory and re downloaded the program.  > Checked Memory addresses M8005 8006 both are Low.  Now, when I am trying to run  my machine it is not giving output to two Servos while a conveyor operates when started from the HMI so it means program is inside PLC, right ? Program is attached if someone wants to have a look.  labeling mc 300322.rar
  16. Omron 1S Servo

    Hello:           Does anyone know the details explanation of the Homing Settings for the Axis? Set the homing operation. 0: Proximity reverse turn/home proximity input OFF 1: Proximity reverse turn/home proximity input ON 4: Home proximity input OFF 5: Home proximity input ON 8: Limit input OFF 9: Proximity reverse turn/home input mask distance 11: Limit inputs only 12: Proximity reverse turn/holding time 13: No home proximity input/holding home input   Limit Input referring to Input (I/O) ? How about Proximity Input ? It is confusing with the terms. The manual has no explanation for each of the above selection.   Any one?   Simon
  17. Hi, I need help with my program. How do I include the fractional part of the position I set for encoder? I have an Omron PLC and using cx programmer.  I need to command my servo (from HMI number input) to move to a certain position. Now using a manual computation, my servo is supposed to move 95.65mm, however, using my plc program, the resulting position doesn't include the 0.65. I used the FIXL instruction to convert my result from float to 32 bit and it removed the fractional part of the value.   Thank you!
  18. Hi, I have to implement an axis control in a NX1P2 PLC using an inverter (3G3MX2) and an encoder cabled on a EC0122 board. I found something similar implemented  on a CJ2M PLC, but I have no idea how to set up the axis in the configuration of sysmac studio and how to implement the control. Can someone help me? Some sample to catch out the configuration?   Thanks a lot Andrea
  19. Hey y'all- I have an application that uses an Allen Bradley servo with a brake and a linear actuator to lift a plate vertically. While maintaining a position, the servo drive (Kinetix 5500) will occasionally fault due to over-torque.  I'm thinking it could possibly be due to mechanical issues i.e. bearings in the actuator but my initial thought would be that it would fault while moving up/down as well, so far I've only ever seen it fault while holding a position. This leads me to suspect that there may be something off in the control loop. I'm not involved in the setup but I know we use load observer and I reckon we use auto-tune. Other than that, I wonder if it's something to do with the brake. I also read about mechanical resonance in the manual which seems like a stretch but it could be contributing, the frame that the actuator/motor is attached to does vibrate a fair bit.  I'm familiar enough with basic motion control using Allen-Bradley and understand the basic concepts behind the servo/control loop. However I'm at a loss for why the servo/drive would spontaneously over-torque while maintaining a position.  How would you guys approach troubleshooting this further/solving this issue?  Many thanks!
  20. Problem during tuning

    Hi! I would like to do some tuning on our machine, but the problem is that the machine stops and drops origin positions. I selected User Command method with Basic setting. After 5sec I started the tuning, the machine stops with the roblem of that axis. Is there a parameter bit that goes high (or low) during tuning? There're no strange sounds nor movements..even the amplifier doesn't give error code. Is there something else that i should check? In the Servo-Adjustments parameters, One Touch Tuning setting I found the Permissible Overshoot Amount Level is set to 0.  Can it be the problem? 
  21. ello I have a powerflex 400 of 25HP for a 60amp 25HP motor, the motor have a belt that move the clarifier of milk. It is a process that requires strength to move.So I try with the motor without the clarifier the vdf works well with a constant amp of 12 to the max of 50hz that is set up with a ramp of 600 sec.Then I try with the belt that move the clarifier... The vdf start the ramp with a wird amp behavior like 10 sec 100 amp and then 13 amp for 10 sec.When it gets to 50hz (the max) it starts the same behavior 13 amp when it reach the max RPM and when it decrease a little bit it gets 100 amp to get to the max RPM again.In this vdf powerflex 400 I didn't see the % of torque options that the last one Fuji had.Someone told me that powerflex 400 is not for power processed, they are focus in pumps and blowers more alike, and that I need a vdf vectorial like a powerflex 725.What do you think...PD: as the 100 amp is like 10 sec the protections dont show up. PD: I made a try with water and hot water, in that point with the max hz  (and 6800rpm) when the hot water start to flow the amp gets constant in 75 amp, but the motor dosnt get to the 6800 rpm again it just keep trying in 6700rpm and it mantains the 75amp triggering the motor protection for overload.
  22. Hi there I was reading this thread: And trying to create 3 axes. 1 virtual axis and 2 real axis, I would like to use MC_GearIn for each real axes so both real ones follow  the virtual axis (so both can move in sync motion). But my question is: If I give Move cmd(Absolute or relative)to master virtual axis and since it's virtual, it is not going to move then how can the other real ones follow the master(assuming that it's literally electronic gearing).  Any help will be appreciated!
  23. 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
  24. Hi there This attached pic I got from Omron motion control manual. I am trying to wrap my head around it. Does it mean that the slave servo axis is gonna follow master encoder axis using GearIn FB?? If so, then Can we executive Move FB on encoder axis? Looking forward to your responses.  
  25. Axis Permanent Control

    Hi Guys, How can I bring an axis into permanent control? that as soon as a value changes, the axis reacts. My Hardware FX5U, FX5SSC MR-JE-20B. Thanks a lot.
