The inverter automatically acknowledges faults under the following conditions:
 p1210 = 1: always.
 p1210 = 4 or 6: If the command to switch-on the motor is available at a digital input or via the
fieldbus (ON command = HIGH).
 p1210 = 14 or 16: never.
2
The inverter attempts to automatically switch-on the motor under the following conditions:
 p1210 = 1: never.
 p1210 = 4, 6, 14 or 16: If the command to switch-on the motor is available at a digital input or via
the fieldbus (ON command = HIGH).

The start attempt is successful if flying restart has been completed and the motor has been
magnetized (r0056.4 = 1) and one additional second has expired without a new fault having
occurred.
