Applicable cables and wiring length

Select a recommended size cable to ensure that the voltage drop ratio is within 2%.
If the wiring distance is long between the inverter and motor, the voltage drop in the main circuit will cause the motor torque to
decrease especially at a low speed.
The following tables show a selection example for the wiring length of 20 m (at 440 V input power supply).
