Stator Resistance (Rs) for Induction Motor 2
Default: Depending on the
model power
05-19
Rotor Resistance (Rr) for Induction Motor 2
Default: 0.000
Settings
0.000–65.535 Ω
05-20
Magnetizing Inductance (Lm) for Induction Motor 2
05-21
Stator Inductance (Lx) for Induction Motor 2
Default: 0.0
Settings 0.0–6553.5 mH
05-22
Multi-motors (Induction) Selection
Default: 1
Settings 1: Motor 1
2: Motor 2
 Sets the motor operated by the AC motor drive. Multi-motors selection only supports single control
mode. For example, when you set motor 1 as SVC control mode, the control mode of motor 2 is
also set as SVC.

-connection Switch for an Induction Motor
Default: 0.200
Settings 0.000–60.000 sec.
 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.
