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