5.10.8
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
. 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.
Note!
Up to and including version 02.00.00
, this function may only be activated for the
following motor control types:
•
V/f characteristic control (VFCplus)
•
V/f characteristic control - energy-saving (VFCplusEco)
For all other motor control types, this function must not be activated because the set
control mode would not work in that case!
From version 12.00.00
, this function may be activated for all motor control types with
the exception of the ones for synchronous motor.
The activation of this function does not affect the control types for synchronous motor
since these control types require an in-phase connection of the synchronous motor.
