Siemens F036 fault code meaning

Series: 6RA70

No armature current flowing

DC drive

Meaning: (Valid in operating statuses – –, I, II.) This monitoring function responds if the armature firing angle remains at the fixed rectification limit for longer than 500 ms and the armature current is below 1% of the rectifier rated DC armature current. Possible fault causes: Open circuit in the armature circuit (e.g. blown DC fuse, open circuit, etc.). Incorrect setting of the fixed rectification limit αG (P150). Drive operating at the αG limit (e.g. due to supply undervoltage). EMF too high because the maximum speed is set too high; see P083, P115, P143, P741. EMF too high because field weakening is not selected (see P082). EMF too high because the field current is set too high (see P102). EMF too high because the field weakening transition speed is set too high (see P101).
