7.5.7 Wiring to Power Supply and Motor
・We want to connect a power supply to the inverter.
・We want to connect a motor to the inverter.
・Connect R, S, T (L1, L2, L4) to the AC power
supply.
・Connect U, V, W (T1, T2, T3) to the motor.
・The common wiring examples are shown below.
・ Use the input power supply within the
range shown below.
Voltage
class
Input range
200V class 200-240VAC (allowable variation
range: +10%/-15%)
Power supply frequency: 50Hz/60Hz
(variation range: ±5%)
400V class 380-500VAC (allowable variation
range: +10%/-15%)
Power supply frequency: 50Hz/60Hz
(variation range: ±5%)
・Driving a 200V motor using a 400V-class
inverter may burn the motor.
