7.2.2 Direction of rotation changeover
Description
Due to the direction reversal in the setpoint channel the drive can be operated in both
directions.
Use the p110 or p111 parameter to block negative or positive direction of rotation.
Note
If an incorrect rotating field was connected when the cables were installed, and the rotating
field cannot be corrected by swapping the motor cables, it can be corrected when
commissioning the drive via p1821 (rotating field direction reversal) by changing the rotating
field and thus enabling a direction reversal (see section "Direction reversal").
Prerequisites
Direction of rotation changeover is triggered:
● via PROFIBUS by means of control word 1, bit 11
● via the cabinet operator panel (LOCAL mode) with the "direction of rotation changeover"
key.
Note
Note that only one direction of rotation is enabled in the factory setting when control is
carried out via the AOP30.
