P1210 = 0: Automatic restart locked (this is a practical setting for a networked drive)
After the line supply voltage returns, possible faults must be acknowledged. After this, the ON
command must be switched-in again in order that the inverter starts.
P1210 = 1: Fault acknowledgment after ON command (P1211 locked)
After a power failure, the inverter automatically acknowledges all faults (it resets them), as soon as
the line supply voltage returns.
•
•
•
P1210 = 2: Automatic restart after power failure - no additional start attempts (P1211 locked)
After power failure, the inverter automatically acknowledges fault F0003 (resets it), as soon as the
line supply voltage is available again; and automatically restarts.
•
•
•
P1210 = 3: Automatic restart after a line supply undervoltage or fault - with additional start attempts
(P1211 enabled)
After a line supply undervoltage, the inverter automatically acknowledges all faults (resets them), as
soon as the line supply voltage is again available; and automatically restarts.
•
•
•
P1210 = 4: Automatic restart after a line supply undervoltage (P1211 enabled)
After power failure or a line supply undervoltage, the inverter automatically acknowledges fault F0003
(resets it), as soon as the line supply voltage is again available; and automatically starts.
•
•
•
P1210 = 5: Automatic restart after power failure and fault (P1211 locked)
After a power failure, the inverter automatically acknowledges all faults (resets them), as soon as the
line supply voltage is again available; and automatically starts.
•
•
P1210 = 6: Automatic restart after line supply undervoltage / power failure or fault (P1211 locked)
The inverter automatically acknowledges all faults (resets them), as soon as the line supply voltage is
again available; and automatically starts.

Principle of operation of the automatic restart
Faults due to a line supply undervoltage are not automatically acknowledged.
The motor does not automatically start.
The motor only starts to rotate again if an ON command is issued again after the line supply
voltage returns.
All other faults are not automatically acknowledged.
Faults due to a line supply undervoltage are not automatically acknowledged.
Switching the ON command in the de-energized state only results in an automatic start if the
inverter was in the "ready" state when the power failed.
This behavior is independent of the power failure or line supply undervoltage.
Switching the ON command in the de-energized state has no effect, if the inverter was "ready"
before the power failure.
The number of start attempts can be set. (If the automatic restart is interrupted due to a new fault)
All other faults are not automatically acknowledged.
An ON command in the de-energized state has no effect.
The number of start attempts can be set. (If the automatic restart is interrupted due to a new fault)
Faults due to a line supply undervoltage are not automatically acknowledged.
Switching the ON command in the de-energized state always results in automatic restart.
Possible faults are first automatically acknowledged.
This behavior is independent of the power failure or line supply undervoltage.
If the ON command is switched-on during the power failure, then an automatic start is always
formed. Possible faults are first automatically acknowledged.
