 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/-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
 Pr.05-24 is used to enable/disable Y-connection/- 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 - connection.

 Pr.05-25 is used to set the switch delay time of Y-connection/-
 When output frequency reaches Y-connection/-connection switch frequency, drive will delay by
Pr.05-25 before multi-function output terminals are active.
