You can apply Pr.05-23–Pr.05-25 in a wide range of 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 as 1, the drive uses the Pr.05-23 setting and current motor frequency, and
