Control SEW MovidriveB with M580 via Ethernet/IP
RiLo73 posted a topic in Modicon / Telemecanique / Schneider Electric
Hey there, I want to control a SEW MovidriveB with option DFE33B via Ethernet/IP with my M580. I added the Movidrive in the DTM-Browser but I am not able to see the Process Data Words of the converter. Is there someone who can show me an example of how to configure this in Control Expert? I want to use the "extended positioning via bus" of the SEW-Converter so I should have 6 Process Data Words. I think the .eds-File may be false or corrupted, because i can't find the settings of the PI- and PO-Words in Control Expert. If i open the .eds-File in Editor i can see them. Sorry for the bad english. Greetings from Germany -
508A panel needs to switch a 120v hot from outside the cabinet
abrahamsolar posted a topic in Control Panel Building
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. -
Hello, I have a PIDE Instruction to control a control valve. The CV minimum is 6% and Max is 100% But when ever the SP is not reached and it has to lower the CV it goes to zero rather than maintaining minimum of 6%.

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.

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.

how to import XHW files in Control Expert
runy29 posted a topic in Modicon / Telemecanique / Schneider Electric
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 -
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

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!

Training Recommendations for Control Panel Building
LuisGonzalez posted a topic in Control Panel Building
Hello everyone, I'm seeking recommendations for training programs or resources focused on building control panels. I have a basic understanding but want to enhance my skills in design, wiring, components, safety, and troubleshooting. If you have attended any reputable hands-on training programs or know of online courses, I would greatly appreciate your suggestions. Any personal experiences or tips are also welcome. Thank you for your assistance! Best regards, -
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.

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.

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

Powerflex 400 25HP wird amp behavior
Demetrio Urrea posted a topic in Allen Bradley / Rockwell Automation
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. -
How long could be INT array. For example can I build INT[365] or DINT[365]? When I use more than [32] my controller fails. Thanks.

NX1P2 Motion Control change output device with code
BrunoRamos posted a topic in NJ Series / Sysmac Studio
Hi everyone, To explain the problem a little bit: I have 2 systems that are equal, they have 1 PLC, 1 Inverter and 1 Servo Axis (Image01). The devices are connected via EtherCat. The thing here is tht in these systems the PLC and Servo Axis is the same but the inverter is different. My goal is to have the same project on both systems and depending on the inverter detected use the correct program. What worked: If I add the 2 Inverters and 2 Servo Axis on the project on different nodes (Image02), I can detect which is present using the variable _EC_EntrySlavTb[n]. My issue is that if I want to make more replicas of the systems using different inverters I will eventually hit the Axis Number limit for the PLC while in reality I am only using on Servo Axis at a time. What I wanted: I would like to be able to control 1 Servo Axis with 2 different inverters (only one active per PLC) (Image03). What I tried: The axis parameters can be set using a variable of the type _sAXIS_PARAM, however it seems that the option to change the axis basic settings is not available (Manual: NJ/NX-series Motion Control Instructions Reference Manual (W508) page 5-58) (Image04). The axis basic settings is where the definition of the output device plus control words are set (Image05). Is there a work around to solve this issue? I would really like to avoid having to manually change the output device for the Servo Axis every time I make an update on all the systems. Best Regards, BR -
Good afternoon, I have a problem in an application for a rotary knife, I'm using a MR-JE-B servo to make this movement, while my material is powered by an inverter connected to a modbus rs485 network, with a 5v encoder connected directly in motion. I'm having some problems and I think it's my cam curve. I have a very high refeneration, and the system doesn't obey the size of the length I want the cut. It always cuts the same size, regardless of the configuration I use, it always cuts to 245mm. Put some photos, how are my settings. Grateful in advance, if anyone can help me.

Hi: I need to change an old PLC with NX1p2 to control 3 servo motor by means of Analog Outputs couple with encoders, My job is to change the PLC only. So the servo drives and drivers are untouchable (No budget and involve too much mechanical works). I observed that Sysmac Sttudio Axes setting has this: Servo Axes, Encoder axes, Virtual Servo Axis and Virtual Encoder Axes. I believe the Encoder Axes couple with Analog Output is able to to do the Job? If so, what function block should i use? If no, do any body have a suggestion of any function block i can use? Thanks
