Startup attempts (p1211) and wait time (p1212)
p1211 is used to specify the number of startup attempts. The number is internally
decremented after each successful fault acknowledgment (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 startup attempts are made.
Note
A startup attempt immediately starts when the fault occurs.
The faults are automatically acknowledged in intervals of half the waiting time p1212.
After successfully acknowledgment and the voltage returns, then the system is automatically
powered-up again.

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
acknowledgment and a fault re-occurring if the signal ON/OFF1 (con-
trol 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 acknowledg-
ment and a new fault must be at least 1s.
For p1210 = 1, fault F07320 is not generated if the acknowledge at-
tempt failed (e.g. because the faults occurred too frequently).
An automatic restart is only carried out, if fault F30003 has also oc-
curred 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_INF1), fault
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. For the case that only the phase voltage fails, time moni-
toring can be set using p1213.
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 at-
tempts is defined in p1211. Monitoring over time can be set using
p1213.
As for 4: However, existing faults must be acknowledged manually.
This is then followed by an automatic restart.
As for 6: However, existing faults must be acknowledged manually.
This is then followed by an automatic restart.
