Main circuit terminals
2.5.4
Applicable cables and wiring length
Select a recommended cable size to ensure that the voltage drop will be 2% or less.
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 table indicates a selection example for the wiring length of 20 m (440 V input power supply).
