Automac start aer switching on the mains voltage
The automac start can be acvated in 0x2838:002 (P203.02).
Precondions for the automac start:
•
Flexible I/O conguraon is selected: 0x2824 (P200.00) = "Flexible I/O conguraon [0]"
•
For the start command, a digital input has been congured. (In case of keypad or acvated
network control, an automac start is not possible.)

①
Start at power-up = "O [0]": Aer switching on the mains voltage, a renewed start command is required to start the motor.
②
Start at power-up = "On [1]": Aer switching on the mains voltage, the motor starts automacally if a start command is acve.

1 DC braking Aer start command, the "DC braking" funcon is acve for the me set
in 0x2B84:002 (P704.02).

2 Flying restart circuit Aer the start command, the ying restart circuit is acve.
The ying restart funcon makes it possible to restart a coasng motor
during operaon without speed feedback. Synchronicity between the
inverter and motor is coordinated so that the transion to the rotang
motor is eected without jerk at the me of connecon.

0 O No automac start aer switching on mains voltage. In addion to the
inverter enable, a renewed start command is always required to start the
motor.
