Deceleraon me 1 can be set in 0x2918 (P221.00).
1 DC braking Aer start command, the "DC braking" funcon is acve for the me set
in 0x2B84:002 (P704.02).
4DC braking^ 196
CAUTION!
Deacvate automac DC braking, if a holding brake is used.
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. The course 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.

3 Pre-magnesaon (from version 05.03) This seng corresponds to the seng [0] Normal, but adds the premag-
nesaon of the motor before the rotaon/acceleraon begins. The pre-
magnesaon can reduce the motor current during the acceleraon and
generate a more even acceleraon curve (by avoiding overcurrent situa-
ons).
The premagnesaon funcon is relevant when operang in V/f motor
control modes. The premagnesaon causes a slight delay before the
motor acceleraon begins (typically 50-200 ms, depending on motor
characterisc).

Starng performance aer switching on the mains voltage.
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.
1 On Automac start of the motor aer switching on the mains voltage if the
inverter is enabled and a start command exists.
