Automatic restart inactive
1 Acknowledges all faults
without restarting
Any faults that are present, are acknowledged automatically
once the 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 a fault being acknowledged and another fault occurring
must be at least 1 s.
With P1210 = 1, no F07320 fault is generated if the
acknowledgement attempt faults, for example due to too great a
frequency of fault occurrence.
4 Automatic restart after
power failure, without
additional startup
attempts
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
(A_Infeed), 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. The failure of the
CU's 24 V power supply will be interpreted as a line supply
failure.
For the case that only the phase voltage fails, time monitoring
can be set using p1213.
6 Restart after fault with
additional startup
attempts
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 using p1211. Monitoring
over time can be set using p1213.
14 Restart after power
failure after manual
acknowledgement
As with p1210 = 4. Pending faults must be manually
acknowledged.
This is followed by an automatic restart.
16 Restart after fault after
manual acknowledge-
ment
As with p1210 = 6. Pending faults must be manually
acknowledged.
This is followed by an automatic restart.
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.
