  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.

  3. 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.
  4. Problem: I am getting a control sync fault on 2 recently installed kinetix 5500 but only when my programing PC is connected to the machine network.  Install and setup all went great over a 5 day period.  Then all of a sudden I started to get this fault. Sometimes 100 times in an hour.  As soon as I go offline, and unplug my PC the problem goes away.  I have also tried another PC connected to the Machine network and still get the same result.  Sometimes machine can run for hours with my PC connected with no problem.  I do not have to be online with controller for fault to occur. Setup: I have the 2 K5500's ethernet ports daisy chained together, and then connected via shielded CAT 6 cable directly to port 2 of the Compact Logix Controller Coarse Update is set to 3.5ms and utilization's are at 33% and below.(I have tried the default 2ms with same results) Ethernet modules are configured with FW rev 7.013. Machine network is isolated.(not connected to plant network or internet) Equipment: Compact logix L33ERM Running version 30.01. There are a total of four servos in this system all running over ethernet.  2 Kinetix 350's(not affected), and 2 kinetix 5500's. I have tried: separate ethernet cables for each drive ran through a switch different ethernet cables resetting coarse update speed connecting a different PC for programming   I am just not sure where else to go with this.  Thanks in advance for any help.  
  5. Hey everyone, I'm new to programming PLCs and I've run into a problem. I have a Micrologix 1400 Series B PLC, and for the past month, I've been using a free trial of RSLogix 500 Starter. But now, the trial ran out, and so I bought a license for "RSLogix Micro Starter". The problem is that when I downloaded my updated file to the PLC for the first time with micro starter, the PLC's outputs don't work anymore. I checked the PLC screen and the inputs from the HMI screen are getting recognized, but the inputs from the physical sensors are not. Also, none of the outputs are being activated on the PLC at all, which I can tell by looking at the I/O status on the PLC screen itself. I then uploaded a new test program, where you press a button and a light turns on, but that doesn't work either. I haven't changed any of the physical wiring, only thing I've changed is that I'm using RSLogix Micro Starter as opposed to RSLogix 500 Starter. I spoke to a Rockwell technician about this and he said that there shouldn't be any problem, as I haven't done anything wrong. So I now ask everyone on this forum if they could help me out a bit.
  6. Hello everyone, I'm trying to import the I/O module configuration file (extension XHW), but this option is blocked in Control Expert. I'm trying to import an existing configuration file so that I don't have to reconfigure the I/O boards manually. Does anyone know how to enable these import and export options or is there another method to import the file? Thanks 
  7. I have this hardware configuration of an extension rack for a M580 PLC projet using EcoStruxure Control Expert I export the.XHW file by following the procedure below: https://www.se.com/uk/en/faqs/FAQ000256454/ And I am trying to rename the DD1602 card using the file, however, when I rename the card as a show in the next image (selected in green), and re-change the file to the .XHW extension, when I re-import it into Control Expert, I get an error saying: unknown fatal exception, even though the only change I've made is to the name of the card. I know I can rename IODDTs instances manually in Control Expert, but in fact I'm trying to automate the process of renaming IODDTs because I have a lot of IODDTs to rename, which is why I thought of using the XHW file. Does anyone have an idea of what I could do? Thanks in advance
  8. Hello everyone,   I'm working on a project where I'm using Vtscada Light to communicate with a MicroLogix 1200 PLC. Currently, I can read values from the PLC without any issues. However, I'm facing difficulties when attempting to write values back to the PLC.   Setup: PLC: MicroLogix 1200 SCADA Software: Vtscada Light Communication: Rockwell Driver with a serial port and serial-to-ethernet converter   I'm looking for guidance on the proper method to write values to the. If anyone has experience with this setup or similar, your insights would be much appreciated.   Thank you for your help!  
  9. Hi guys, my site uses mainly Mitsi PLC's & HMI's so not familiar with AllenBradley but i have two Micrologixe 1200 PLC's connected to Panelview 300 HMI's. The machines are twenty plus years old and now both HMI's are barely legible as the screens are so dim.  I want to upgrade the HMI's as they are obsolete but my problem is, the program within the PLC is Password Protected and i cannot read, upload or download to the PLC.  The original manufacturer has been taken over some years ago and no-one knows the password. They have sent me an old program that could possibly work which is not password protected, but i cannot download it to the PLC without the original Password. Can anyone help me?
  10. Hi everyone, I have a question for you all, Is possible to configure CJ2M-CPU11 with tags trough network configurator to connect Control Logix PLC using EthernetIP? I did a configuration with CJ2M-CPU31 and Control Logix PLC with no problem, but now I need to communicate CJ2M-CPU11 with Control Logix PLC using EthernetIP. Some of you did this configuration between this two PLC before? Regards!
  11. 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

  13. 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.
  14. 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.            
  15. Hi from Colorado, Panel Builders @ MRPLC~ I bought a custom 508A assembly from a UL shop (277/480v 3 phase). The prototype didn't work out very well so I'm revising the design for next time. Before I present my "red line" revisions to the fabricator, could someone advise if I'm OK to simplify part of the work in a particular way? I just need to make sure my simplification doesn't run afoul of the 508A standard. My clients requested that a ten watt 120vAC amber LED (distant from the 508A cabinet) should light up whenever the 3 phase bus is energized. The panel fabricator provided an SSR solid state relay to close whenever 277v shows up across the "input" terminals & they fused the 277v hot for the input so that's all good. The "output" terminal is "single pole normally open", rated for 10 amps. The power that I'm sending in from outside the cabinet is from a small UPS system where the inverter is rated for 250VA's--so it can't deliver more than two amps @ 120vAC.  It seems to me that I don't need the series fuse that the shop provided to protect the 10 amp rating on the SSR--since my input power is already current limited. It also seems that I don't need to bring the associated single phase neutral wire into the 508A cabinet at all--since the neutral is never switched & it's doing nothing inside the 3 ph. assembly. If I revise the drawings along these lines, I'll eliminate two terminal blocks, a cc fuse/fuse holder & some wire...and this part of the assembly will be simpler & more intuitive.  Basically, I want to treat the SSR like a switch leg for the light, running only a 120v hot wire to & from the SSR output terminals. I don't want to revise the drawings, however, unless I'm sure the fabricator won't have to change them back to comply with UL 508A. I don't own the UL "standard" document & I don't know the peculiarities...but I'm sure some of the forum members do.  Should I add signage to explain that the 120v hot must be current limited or OCPD protected before it enters the 3 phase cabinet? Thanks in advance for any coaching or suggestions.      
  16. control panel for sale

    Hi all, Hope everyone is doing well. I'm currently in the process of starting a home based control panel shop. I have about 8 years of control panel building experience and about 2-3 years of being shop team lead/design engineering. I have been planning this for years and now I have my shop full of necessary tools and material to build small/medium sized panels. I have gone through all the training and examination(which was not easy) to be able to produce UL508A approved panels. My goal is to produce a steady work load with great quality. Now I just need an opportunity with customers which I find to be the hard part. I have been contacting local industries but haven't had any luck. If anyone out there is seeking control panels built at a good competitive rate please advice.

Please contact us if interested. We can send more details as needed. We typically need 20-30 panels in a year.
  18. Hi All, I'm new to using PLC, and my background is majorly programming. I am learning how to control a PLC over the internet using HTTP or TCP/IP. I have a Mitsubishi PLC Melsec FX-5U 32MR and my requirement is, I want to send create a setup where the PLC works more like a Client on the network and reads values from the server (which is a computer). The outputs on the PLC are controlled by the values on the database in server.  So, lets assume I have a value like this on the server "1,0,0,1,0,1", it should translate like below: Y0 = 1 Y1 = 0 Y2 = 0 Y3 = 1 Y4 = 0 Y5 = 1 Is there any guidance where I can read through and learn how to do this. I would prefer doing it by ST programming and not Ladder.
  19. Logic issue, or problem with Control Expert 14.1?   Pop-up box, followed by Control Expert crash.  PLC seems to be running fine. "Control Expert Fatal Error" "The thread tried to divide an integer value by an integer divisor of zero" Anybody seen this before?  Corrupt file?  Reboot?  Uninstall/reinstall?
  20. Uploaded a program from a micrologix 1400, I added an integer data file. Went to download it, and the processor types were different. I suppose I am just going to change it to match what is on the machine, but why did this happen? The controller was password protected. so maybe it did not get the processor info for some reason. Even when online with the processor, it reads incorrect.  
  21. 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
  22. Hello I am not sure if anyone know how to select cable cross section for 5KW AC motor? Thank you
  23.  I am very green at this and learning online as I have purchased a brand new Micrologix 1400 1766L32BXBA. I am pulling my hair out as I cannot even power an LED or for that matter get any 24 volt reading from the outputs via program. I have even forced them on so shouldnt I be able to see something? I am connected via Ethernet ,Rslinx in concert with using Micro starter software (not lite) and the unit does not show any faults and is in the run mode. I can see the bits forced on the software and on the unit's LCD screen in I/O status. Is there a way to trouble shoot if the unit is bad or I am overlooking something incredibly simple. I do not have any floating inputs or outputs with the common from the power supply and the unit is properly grounded all nice and tidy on a din rail. Like I said I am very new at this so I am sorry if this is a bad question.
  24. Hello everyone, I am a newbie with PLC. I have a Micrologix 1000. The last time I connected with RSLinx easy, however, I change it to DH485 (I do not remember exactly). And now I can not connect it to RSLinx, I tried many times for all types of drivers. Please help me. Thank you very much.
  25. 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.
