Basic functions
6.10 Automatic restart
p1210 Mode
4 Restart after line supply failure,
without additional startup attempts
6 Restart after a fault with additional
startup attempts
14 Restart after line supply failure
following manual acknowledgement
16 Restart after a fault after manual
acknowledgement
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 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 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 acknowledgement and the voltage returns, then the system is
automatically powered-up again.
The startup attempt has been successfully completed if the flying restart and the motor
magnetization (induction motor) have been completed (r0056.4 = 1) and one additional
second has expired. The starting counter is only reset to the initial value p1211 after this
time.
If additional faults occur between successful acknowledgement and the end of the startup
attempt, then the startup counter, when it is acknowledged, is also decremented.
Monitoring time line supply return (p1213)
The monitoring time starts when the faults are detected. If the automatic acknowledgements
are not successful, the monitoring time runs again. If the drive has not successfully started
again after the monitoring time has expired (flying restart and motor magnetization must
have been completed: r0056.4 = 1), fault F07320 is output. The monitoring is deactivated
with p1213 = 0.

Meaning
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.
