Siemens F052 fault code meaning

Series: 6RA70

Optimization run interruption due to an external cause

DC drive

Meaning: (Valid in operating states – –, I, II.) This fault is activated during an optimization run if the rectifier stops operating in state RUN (state I, II or --) as a response to a fault, or if an "Emergency stop" or "Open circuit breaker" command is used. The optimization run is interrupted. Only parameters already optimized before the fault message appeared can be changed. When a "Stop" command is used, this fault message is not activated if the field-weakening optimization run is interrupted after the first field-weakening test point has been recorded, or if the friction and moment-of-inertia compensation optimization run is interrupted after the measurement point at the maximum speed of 10% has been determined. In this case, the run can be interrupted using the "Stop" command so that optimization can be completed in several steps (by repeated starts) for a drive with limited travel. r047, indices 002 ~ 016: 1 Run interrupted because the rectifier is not in state RUN. 2 Run interrupted by an "Emergency stop" command (speed controller reference = 0).
