Configuring the function
Proceed as follows to configure the function:
1. Activate the function for drive objects "Servo", "Vector" or X_INF (all drive objects "Infeed";
i.e. A_INF, B_INF, S_INF).
– Automatic restart: Set mode (p1210).
– Flying restart (only for "Vector"): Activate function (p1200).
2. Set the startup attempts (p1211).
3. Set the wait times (p1212, p1213).
4. Check the function.

Table 8-7 Automatic restart mode
p1210 Mode
0 Disables automatic restart
1 Acknowledges all faults without re‐
starting
4 Restart after line supply failure, with‐
out additional startup attempts
6 Restart after a fault with additional
startup attempts
14 Restart after line supply failure follow‐
ing manual acknowledgment
16 Restart after a fault after manual ac‐
knowledgment
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 unit signals that it is ready). Fault F07320 is signaled if the number of parameterized
startup attempts is exceeded.

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 (control
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 acknowledgment and a
new fault must be at least 1s.
For p1210 = 1, fault F07320 is not generated if the acknowledge attempt
failed (e.g. because the faults occurred too frequently).
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_INF1), fault F06200 has oc‐
curred. 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 monitoring 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 attempts 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.
