Diagnosis fault: Only if 2 consecutive faults are recognized, the monitoring function reports a fault.
5 s Monitoring: Checks, if both inputs STOA and STOB are switched on within 5 s from each other.
In order to achieve robust operation and, for example, exclude electromagnetic interference in the
signal assessment of the diagnosis function, the diagnosis is repeated when an error is detected. The
frequency inverter is switched over only if another error is detected by the diagnosis function in oper-
ation status "STO Enable".
Before the frequency inverter output stages are released:
Check if STOA and STOB are switched on less than 5 s after one another (5s monitoring). If this
−
is the case, the release is prepared.
− Diagnosis for error in stop paths STOA and STOB. If no error is detected in the stop paths and
release has been prepared, the output stages are enabled.
