WIRING
3.2 Wiring fundamentals
3.2.1 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.
400V class (when input power supply is 440V)
Applicable Inverter Type
Terminal Screw Size *
4 Tightening Torque [Nm]
Crimping Terminal
R/L1, S/L2, T/L3 U, V, W
