The troubleshooting guide says: The CONTACTOR CLOSED input in the SEQUENCING LOGIC function block remained  FALSE after a run command was issued

I'm not sure if this alarm is referring to an internal contactor or an external contactor. If the drive is monitoring an internal contactor, you may have a hardware problem.

If it is referring to an external contactor, you can start by verifying the wiring to the external contactor and testing the contactor coil.
Best regards,

When you see contactor feedback, you can usually associate it with welded contacts. That's the way i look at it.
