Siemens F009 fault code meaning

Series: 6RA70

Incoming frequency (armature and field power supply) exceeds 65 Hz

DC drive

Meaning: While one of the fault conditions associated with faults F003 ~ F006, F008, F009 is valid and the auto restart delay is still running, the rectifier remains in operating status 04.0 (armature line supply voltage fault) or 05.0 (field line supply voltage or field current fault). The backup power supply is switched on when the electronics board power supply fault lasts up to several hundred milliseconds. When the "Switch on", "Switch off" and "Jog" functions are edge-triggered (see P445=1), the rectifier cannot restart automatically after the backup power supply has been used. 9.18 Field reversal. See also Chapter 8, "Function diagrams", Figure G200. By changing the current direction in the DC motor field winding (i.e. by field reversal), a drive comprising a single-quadrant 6RA70 rectifier (with only one armature current direction) can oper...
