Cables And Wiring Length - Mitsubishi Electric FR-A720-00030-NA Instruction Manual

Main circuit terminal specifications

Cables and wiring length

(1) Applied cable size
Select the recommended cable size to ensure that a voltage drop will be 2% max.
If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor
torque to decrease especially at the output of a low frequency.
The following table indicates a selection example for the wiring length of 20m (65.62feet).
