Hello everyone, I recently experienced a malfunction with my Omron CQM1-CPU43-E PLC where the RS output to the screen stopped working. After replacing it with a new unit and transferring all data memory and program settings, everything seems to be functioning correctly except for a single stepper motor wired through CN1 into an XW2B-20J6-3 board. The stepper motor is connected to a R88D-UP08H using a R88M-U20030H-ES1 AC servo motor. Although the program is converting Hex to BCD properly, the stepper motor is not receiving the necessary pulses. Could there be a setting that I overlooked during the replacement process causing this issue?
Does the High Speed CounterInterruptfunction need to be used in this process? When downloading all DM, it should restore all settings, but it's a good idea to double-check them under 'Settings' in the project tree. The Pulse Output feature doesn't have any specific settings, unlike the High Speed Counter.Expansion Instructions can be quite tricky. If they aren't mapped correctly, you may encounter a compile error, so it's important to confirm from the original program. Additionally, make sure to double-check the DIP switch settings in the battery compartment for accuracy.
It sounds like you’ve done a thorough job with the replacement, but it might be worth double-checking a couple of things. First, ensure that the wiring and communication settings between the PLC and the stepper motor driver are correctly configured; sometimes, a loose connection or a misconfigured parameter can cause pulse issues. Also, verify the I/O configurations in the PLC settings to ensure that the output meant for the stepper motor is enabled and functioning. If everything seems set up correctly, consider running a diagnostic or using a test program to isolate whether the issue lies with the PLC output or the motor driver itself. Good luck!
