 Set up Pr.01-35 and Pr.05-15 before setting up Pr.05-16 to ensure that the motor operates
normally.
05-17
No-load Current for Induction Motor 2 (A)
Default: Depending on the
model power
Settings
0.00–Pr.05-13 default
 The default is 40% of the motor's rated current.
05-18
Stator Resistance (Rs) for Induction Motor 2
Default: Depending on the
model power
Settings
0.000–65.535 Ω
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-Motor (Induction) Selection
Default: 1
Settings
1: Motor 1
2: Motor 2
3: Motor 3 (VF or SVC control mode only)
4: Motor 4 (VF or SVC control mode only)
 Sets the motor operated by the AC motor drive. Multi-motor selection only supports single
control mode. For example, when you set motor 1 as SVC control mode, the control mode of

Frequency for Y-connection /-connection Switch for an Induction Motor
Default: 60.00
Settings
0.00–599.00 Hz
05-24
Y-connection /-connection Switch for an Induction Motor

05-25
Delay Time for Y-connection/-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 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
