Posted 11 Oct 2019 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 Share this post Link to post Share on other sites
Posted 11 Oct 2019 Welcome to the forum. MOV instruction will only move 4 digits. Use MOVL to move 8 digits. Right now your target frequency is set to 0. Additionally your plc has relay outputs. It will never be able to switch at 50000 hertz. 1 person likes this Share this post Link to post Share on other sites

Thanks for your reply yes I just found out that my outputs are relay type, I changed the mov instruction to movl for the target freq and also I lowered the Frequency to 10Hz but the outputs still off, is the plc must be transistor type to make the outputs toggle, Edited 11 Oct 2019 by LRH095 Share this post Link to post Share on other sites
Posted 11 Oct 2019 High speed outputs will ONLY work if the model has transistor outputs. Share this post Link to post Share on other sites

Thanks for your reply , so the CP1E-N40S1DR-A is relay output ,can I add a transistor output module as an expansion and use its output for pulsing? Share this post Link to post Share on other sites
Posted 12 Oct 2019 No, expansion units cannot be used for pulse output. Only CPU OUT 100.00,100.01,100.02 and 100.03. Pages from W480-E1-04 CP1E Software.pdf 1 person likes this Share this post Link to post Share on other sites

Posted 12 Apr 2022 hye LRH095 im having some trouble with my project .. in my project im need to control stepper motor using omron plc cp1e 1. using power supply 24v 2. omron plc cp1e-n20dt-d 3.using stepper driver tb6600 4 using stepper motor Linix so can i ask for your help with the program and wiring this component .. or u can just give me your ladder program and sketch wiring of your component in your last project Share this post Link to post Share on other sites
