p1210
Startup attempts (p1211) and waiting time (p1212)
p1211 is used to specify the number of startup attempts. The number is decremented
internally after each successful fault acknowledgement (line supply voltage must be restored
or the infeed signals that it is ready). Fault F07320 is output when the number of
parameterized startup attempts is reached.
If p1211 = x, x + 1 startup attempts will be made.

Automatic restart mode
Mode
0 Disables automatic restart
1 Acknowledges all faults
without restarting
4 Automatic restart after
power failure, without
additional startup attempts
6 Restart after fault with
additional startup attempts
14 Restart after power failure
after manual
acknowledgement
16 Restart after fault after
manual acknowledgement
Automatic restart inactive
If p1210 = 1, pending faults will be acknowledged
automatically once their cause has been rectified. If further
faults occur after faults have been acknowledged, these will
also be acknowledged automatically. A minimum time of
p1212 + 1 s 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 set to LOW, the time between when
a fault is acknowledged and another one occurs must be at
least 1 s. If p1210 = 1, fault F07320 will not be generated if
the acknowledge attempt fails (e.g., because the faults
occurred too frequently).
If p1210 = 4, an automatic restart will only be performed if
in addition fault F30003 occurs on the Motor Module or
there is a high signal at binector input p1208[1], or in the
case of an infeed drive object (A_Infeed), F06200 is
pending. 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 power
supply will be interpreted as a line supply failure.
If p1210 = 6, an automatic restart will be performed after
any fault or at p1208[0] = 1. If the faults occur one after the
other, then the number of startup attempts is defined using
p1211. Monitoring over time can be set using p1213.
As for p1210 = 4. But pending faults must be
acknowledged manually.
As for p1210 = 6. But pending faults must be
acknowledged manually.
