  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. 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. QD77MS4

    Hi My system : plc Q03ud , simple motion module : QD77MS4 , software : Gx works2 , Application : rotary table and unit degree I send position and speed from HMI ( got 2000 ) , my problem is that when i want send 90 degree for position ( dmov d0 u0\g2006 ) , i have to enter the 9000000 from hmi . and for speed i have similar problem Position hmi ( 9000000 ) ===>> motor rotate 90 degree  Speed hmi (100000) ==>> motor rotate with 100 degree per min
  6. I am trying to create an Alarm handler for an NA5 HMI that can tell the end-user the 1SAN Drive AL Status code and an Annunciation according to the manual: I621. I already am using a similar method to use MFaultLvl.Codes in a Case statement that creates a message found in motion controller manuals. Ie. 16#6449: Fault_Axis0 := '1S Axis Immediate Stop Input'; I want to use the AL Status to create messages based on the Hex Code generated by the Alarm ie 16#20: DriveAlarm_Axis1 := '1S Overload Error'; 20hex being the AL Status from the Drive. However I  cannot find how to access AL Status from the Troubleshooter.   Thanks
  7. 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 
  8. 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
  9. 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. 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.      
  12. 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.

  14. 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.
  15. 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?
  16. Hello Everyone Im working with Coordinated Motion instructions, specifically MCLM instruction and I Would like to know if there is a way to know the exact End position (XYZ) when parameter Command Tolerance is Set since i need to calculate the distance to the end point, there is no problem as long no command tolerance is set cause I can find the distance using  AB=Sqrt ((x2−x1)**2+(y2−y1)**2+(z2−z1)**2)  but as some points have command tolerance the X2,Y2,Z2 are unknown. Hope I was Clear Thank you in Advance.
  17. 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
  18. Hi All, I just start to setup a rotary servo (rotary transmission load type) and the designer pass me the spec of gear ratio 1:100. In my motion scaling page, I set Transmission I:O as 1:100  and then scaling unit is just position unit with 1:1. However, when i jog my rotary servo, it does not reflect the actual position in degree, so I went to read through the manual but still cant quite get how should i configure my scaling so that I can see that when the motor is rotating, i can see it rotate how many degrees? I try to set scaling 360 degree to 1.0 load rev, and the position feedback seems like much more finer....

  24. 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!
  25. 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.
