34251 : Incoming Mains Phase Missing

Hello everyone,

I am looking for some troubleshooting insight regarding the following error on an ABB IRC5 controller:
34251 : Incoming Mains Phase Missing

Currently, the controller is completely powered OFF. I am hesitant to turn it back on out of concern that it might cause physical damage to the hardware components.

Sequence of Events & Timeline:

All of the following activities occurred yesterday:

  • 7:00 AM: Formatted the IRC5’s SD card.
  • 9:00 AM: Jogged the robot successfully and updated the revolution counters. Everything was operating normally.
  • 11:00 AM: The robot was still functioning without any issues.
  • 2:00 PM: Pushed new I/O changes to the controller and executed a warmstart.

Immediately following that warmstart (at 2pm), I was completely unable to move the robot and was greeted with the 34251 error code.

My Questions:

  • Could any of those configuration/software activities (specifically the I/O push or warmstart) have triggered this error?
  • Is it safe to power the controller back on, or should I perform physical voltage/cable checks while it is powered down?
  • What would you recommended be the next step in troublshooting for this error 34251?

I would highly appreciate any advice, experiences, or insights you can share!

Thank you!

update:

I decided to turn the controller back on and the error is still present (It only populated after I tried to turn the motors back on and jog robot (which it wouldn’t allow me to jog obviously).

Anyone have any tips?
