Settings 0.00~599.00Hz
Y-connection/△-connection Switch of Induction Motor IM
Factory Setting: 0
Settings 0: Disable
1: Enable
Delay Time for Y-connection/△-connection Switch of Induction Motor
Factory Setting: 0.200
Settings 0.000~60.000 sec
P.05-23 and Pr.05-25 are applied in the wide range motors and the motor coil will execute the
switch of Y-connection/Δ-connection as required. (The wide range motors has relation with the
motor design. In general, it has higher torque at low speed and Y-connection and it has higher
speed at high speed and connection.
Pr.05-24 is used to enable/disable Y-connection/Δ- connection Switch.
When Pr.05-24 is set to 1, the drive will select by Pr.05-23 setting and current motor frequency to
switch motor to Y-connection or Δ- connection. At the same time, it will also affect motor
parameters.
Pr.05-25 is used to set the switch delay time of Y-connection/Δ- connection.
When output frequency reaches Y-connection/Δ-connection switch frequency, drive will delay by
Pr.05-25 before multi-function output terminals are active.
