WIRING
2.3 Wiring fundamentals
2.3.1 Cable size
Select the recommended cable size to ensure that the voltage drop will be 2% max.
If the wiring distance is long between the inverter and motor, the main circuit cable voltage drop will cause the motor
torque to decrease especially at the output of a low frequency.
The following tables indicate a selection example for the wiring length of 20m.
LD rating (Pr. 570 "Multiple rating setting" = "1")
