1
Acknowledges all faults
without restarting
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 + 1s must elapse between successful fault
acknowledgement and a fault reoccurring if the ON/OFF1
signal (control word 1, bit 0) is at HIGH. If the ON/OFF1
signal is at LOW, the time between successful fault
acknowledgement and a new fault must be at least 1s. If
p1210 = 1, fault F07320 will not be generated if the
acknowledge attempt fails (e.g., because the faults
occurred too frequently).
4
Automatic restart after line
supply failure, no additional
startup attempts
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.
6
Restart after any fault with
additional startup attempts
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.
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.
Note
A startup attempt starts immediately when the fault occurs.
The faults are acknowledged automatically at intervals of half the waiting time p1212.
Following successful acknowledgement and restoration of the voltage, the system is
automatically powered up again.
