P1210 Automatic restart
Enables restart after a mains break or after a fault.
Possible settings:
0 = Disabled
1 = Acknowledges faults on power up – inverter is not started. It is
necessary to toggle the ON command to start the inverter.
2 = Restart after mains break (blackout) / power on
3 = Restart after fault/mains break (blackout / brownout)
4 = Restart after mains break (blackout / brownout)
5 = Restart after mains break/fault, ignoring previous history
Warning:
Setting 2 to 5 can cause the motor to restart unexpectedly!
Note
Auto restart will only work if the ON command remains constantly present. E.g. via a digital
input wire link.
If the motor could still be turning or is possibly still being driven by the load, flying restart
must also be enabled (P1200).
