SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 11/2009
Description: Sets the automatic restart mode (AR).
The parameters must be saved in the non-volatile memory p0971 = 1 in order that the setting becomes effective.
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
Dependency: The automatic restart requires an active ON command, e.g. that is available at 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 CU board boots if the DC link voltage is again present. This automatic power-up sequence can only be inter-
rupted 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. For p1210 = 1, fault F07320 is not generated if the
acknowledgment attempt was unsuccessful, for example, because the monitoring time p1213 index 0 was
exceeded.
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. 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.
