Wiring
Cables and wiring length
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 tables indicate a selection example for the wiring length of 20m.

Cable size
The recommended cable size is that of the HIV cable (600 V class 2 vinyl-insulated cable)
with continuous maximum permissible temperature of 75 °C. Assumes that the ambient
temperature is 50 °C or less and the wiring distance is 20 m or less.
The recommended cable size is that of the THHW cable with continuous maximum
permissible temperature of 75 °C. Assumes that the ambient temperature is 40 °C or less
and the wiring distance is 20 m or less.
(Selection example for use mainly in the United States.)
The recommended cable size is that of the PVC cable with continuous maximum permissible
temperature of 70°C. Assumes that the ambient temperature is 40°C or less and the wiring
distance is 20m or less.
The terminal screw size indicates the terminal size for R/L1, S/L2, T/L3, U, V, W, and a screw
for earthing. (For single-phase power input, the terminal screw size indicates the size of
terminal screw for L1, N, U, V, W, PR, +, – and P1 and a screw for earthing (grounding).)
The line voltage drop can be calculated by the following expression:
Line voltage drop [V]
Use a larger diameter cable when the wiring distance is long or when it is desired to decrease
the voltage drop (torque reduction) in the low speed range.
