 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 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 Y-connection / -connection switch frequency, the drive
delays according to Pr. 05-25 before activating the multi-function output terminals.
