Properties: Vector
Access groups
via HMI:
Description:
„
P0321 - defines the U
d
voltage level under which the line loss will be detected.
„
P0322 - defines the U
d
voltage level that the inverter will try to keep regulated, so that the motor keeps operating.
„
P0323 - defines the U
d
voltage level at which the inverter will identify the return of the line, and from where
the motor must be reaccelerated.
NOTE!
These parameters work together with the parameters P0325 and P0326 for the Ride-Through in
vector control.
