Siemens F002 Fault

The trip level depends on the supply voltage rating:

The F002 fault occurs when the voltage in step 3 (DC link) rises too high, typically above approx. 800V DC for 400V class drives or 400V DC for 230V class drives. The drive triggers a hardware or software shutdown to protect the sensitive capacitors and IGBT modules from exploding or failing catastrophically. siemens f002 fault

Contrary to popular belief, the F002 fault rarely means "the incoming power is too high." While that is possible, the most common culprit is actually the motor acting as a generator. Let’s break down the three primary sources: The trip level depends on the supply voltage

Short circuits between a motor phase and the cable screen/armor, creating capacitance that feeds back to the DC link. Contrary to popular belief, the F002 fault rarely
