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
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
Refer to: F30003
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.
Caution: 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 acknowledg-
ment, then these are also automatically acknowledged again. p1211 has no influence on the number of acknowl-
edgment attempts.
Re p1210 = 4:
An automatic restart is only performed if fault F30003 has occurred on the power unit. If additional faults are pres-
ent, then these faults are also acknowledged and when successful, starting continues. If the 24 V Control Unit
power supply fails, then this is interpreted as a line supply failure.
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 inter-
rupted with either OFF2 or OFF3.
Description: Sets the start attempts of the automatic restart function for p1210 = 4, 6, 14, 16, 26.
Dependency: Refer to: p1210, r1214
Refer to: F07320
Caution: A change is only accepted and made in the state "initialization" (r1214.0) and "wait for alarm" (r1214.1).
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.
