Starting attempts (p1211) and waiting time (p1212)
p1211 is used to specify the number of starting attempts. The number is internally
decremented after each successful fault acknowledgement (line supply voltage must be re-
applied or the infeed signals that it is ready. Fault F07320 is signaled if the number of
parameterized startup attempts is exceeded.
When p1211 = x, x + 1 starting attempts are made.

Restart after line supply failure
following manual
acknowledgement
Restart after a fault following
manual acknowledgement
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 in
addition, fault F30003 has occurred at the Motor
Module, there is a high signal at binector input
p1208[1], or in the case of an infeed drive object
(X_INF ), fault F06200 has occurred. If additional
1)
faults are present, then these faults are also
acknowledged and when successfully
acknowledged, the starting attempt is continued.
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 start 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.
