5.7.6

Phase sequence reversal for correcting misconnected UVW motor phases

If the motor phases are misconnected at the inverter output (e.g. phase u takes the place of phase

v), the motor will rotate in the wrong direction.
To correct such misconnected motor phases, the rotating field of the controller's output can be

reversed by selecting "1: Inverted" in

C00905

. In this case, a phase will be reversed at the output of

the inverter.
This function does not have any effect on setpoints and actual values, i.e. the polarity of the speed

setpoint/actual speed value, actual torque, output frequency, and AngleOffset do not change.

Tip!
Cases of application for this function:

• Phase sequence reversal in case of misconnected motor phases.
• Setting of the correctly signed direction of rotation for inversely mounted motors.
