WIRING
2.2.3 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.
200V class (when input power supply is 220V)
400V class (when input power supply is 440V)
