● You can apply Pr.05-23–Pr.05-25 in wide range motors, and the motor coil executes the Y-connection/∆-

connection switch as required. The wide range motors are related to the motor design. In general, the motor

has higher torque with low speed Y-connection and has higher speed with high speed ∆-connection.

● Pr.05-24 enables and disables the switch of Y-connection/∆-connection.

● When you set Pr.05-24 to 1, the drive uses the Pr.05-23 setting and current motor frequency, and switches the

current motor to Y-connection or ∆-connection. You can switch the relevant motor parameter settings

simultaneously.

● Pr.05-25 sets the switch delay time of Y-connection/∆-connection.

● When the output frequency reaches the Y-connection/∆-connection switch frequency, the drive delays

according to Pr.05-25 before activating the multi-function output terminals.
