Value: 0: Inhibit automatic restart
1: Acknowledge all faults without restarting
4: Restart after line supply failure w/o additional start attempts
6: Restart after fault with additional start attempts
14: Restart after line supply failure following man. acknowledgment
16: Restart after fault following manual acknowledgment
26: Acknowledging all faults and reclosing for an ON command
Recommend.: For brief line supply failures, the motor shaft may still be rotating when restarting. The "flying restart" function (p1200)
might need to be activated to restart while the motor shaft is still rotating.
Dependency: The automatic restart requires an active ON command (e.g., via a digital input). If, for p1210 > 1, there is no active
ON command, then the automatic restart is interrupted.
When using an Operator Panel in the LOCAL mode, then there is no automatic start.
For p1210 = 14, 16, a manual acknowledgement is required for an automatic restart.
Refer to: p0840, p0857, p1267
Danger: If the automatic restart is activated (p1210 > 1) if there is an ON command (refer to p0840), the drive is powered up
as soon as any fault messages that are present can be acknowledged. This also occurs after the line supply returns
or the Control Unit boots if the DC link voltage is present again. This automatic power-up sequence can only be
interrupted by withdrawing the ON command.
Notice: A change is only accepted and made in the state "initialization" (r1214.0) and "wait for alarm" (r1214.1). When faults
are present, therefore, the parameter cannot be changed.
For p1210 > 1, the motor is automatically started.
Note: Re p1210 = 1:
Faults that are present are automatically acknowledged. If new faults occur after a successful fault acknowledgment,
then these are also automatically acknowledged again. p1211 has no influence on the number of acknowledgment
attempts.
Re p1210 = 4:
An automatic restart is only performed if fault F30003 has occurred on the power unit. If additional faults are present,
then these faults are also acknowledged and when successful, starting continues.
Re p1210 = 6:
An automatic restart is carried out if any fault has occurred.
Re p1210 = 14:
As for p1210 = 4. However, faults that are present must be manually acknowledged.
Re p1210 = 16:
As for p1210 = 6. However, faults that are present must be manually acknowledged.
Re p1210 = 26:
The same as for p1210 = 6. For this mode, the switch-on command can be entered with a delay. The restart is
interrupted with either OFF2 or OFF3. Alarm A07321 is only displayed if the cause of the fault has been removed and
the drive is restarted by setting the switch-on command.
Description: Sets the start attempts of the automatic restart function for p1210 = 4, 6, 14, 16, 26.
Dependency: A change is only accepted and made in the state "initialization" (r1214.0) and "wait for alarm" (r1214.1).
Refer to: p1210, r1214
Notice: After fault F07320 occurs, the power-on command must be withdrawn and all of the faults acknowledged so that the
automatic restart function is re-activated.
After a complete power failure the start counter always starts with the counter value that applied before the power
failure, and decrements this start attempt by 1. If a further attempt to acknowledge is started by the automatic restart
function prior to power failure, e.g. when the CU remains active on power failure longer than the time p1212 / 2, the
fault counter will already have been decremented once. In this case, the start counter is thus decreased by the value
2.
Note: A start attempt starts immediately when a fault occurs. The start attempt is considered to been completed if the motor
was magnetized (r0056.4 = 1) and an additional delay time of 1 s has expired.
