Meaning
Automatic restart inactive
Any faults that are present, are acknowledged automatically once the
cause has been rectified. If further faults occur after faults have been
acknowledged, then these are also again automatically acknowledged.
A minimum time of p1212 + 1s must expire between successful fault
acknowledgement and a fault re-occurring if the signal ON/OFF1
(control word 1, bit 0) is at a HIGH signal level. If the ON/OFF1 signal
is at a LOW signal level, the time between a successful fault
acknowledgement and a new fault must be at least 1s.
For p1210 = 1, fault F07320 is not generated if the acknowledge
attempt failed (e.g. because the faults occurred too frequently).
An automatic restart is only carried out, if fault F30003 has also
occurred at the Motor Module, or there is a high signal at binector
input p1208[1], or in the case of an infeed drive object (X_INF
F06200 has occurred. If additional faults are pending, then these faults
will also be acknowledged; if this is successful, the startup attempt will
be resumed. The failure of the CU's 24 V supply will be interpreted as
a line supply failure.
An automatic restart is carried out after any fault or for p1208[0] = 1. If
the faults occur one after the other, then the number of startup
attempts is defined in p1211. Monitoring over time can be set using
p1213.
As for 4: However, existing faults must be acknowledged manually.
As for 6: However, existing faults must be acknowledged manually.
