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).

*1 For the 02150 or less, the cable size is that of the cable (HIV cable (600V class 2 vinyl-insulated cable) etc.) with continuous maximum
permissible temperature of 75°C (167°F). Assumes that the ambient temperature is 50°C (122°F) or less and the wiring distance is 20m
(65.62feet) or less.
For the 02880 or more, the recommended cable size is that of the cable (LMFC (heat resistant flexible cross-linked polyethylene insulated cable)
etc.) with continuous maximum permissible temperature of 90°C (194°F). Assumes that the ambient temperature is 50°C (122°F) or less and
wiring is performed in an enclosure.
*2 The recommended cable size is that of the cable (THHW cable) with continuous maximum permissible temperature of 75°C (167°F). Assumes
that the ambient temperature is 40°C (104°F) or less and the wiring distance is 20m (65.62feet) or less.
(Selection example for use mainly in the United States.)
*3 For the 00610 or less, the recommended cable size is that of the cable (PVC cable) with continuous maximum permissible temperature of 70°C
(158°F). Assumes that the ambient temperature is 40°C (104°F) or less and the wiring distance is 20m (65.62feet) or less.
For the 00760 or more, the recommended cable size is that of the cable (XLPE cable) with continuous maximum permissible temperature of 90°C
(194°F). Assumes that the ambient temperature is 40°C (104°F) or less and wiring is performed in an enclosure.
(Selection example for use mainly in Europe.)
*4 The terminal screw size indicates the terminal size for R/L1, S/L2, T/L3, U, V, W, and a screw for earthing (grounding). For the 00240 and 00330,
screw sizes are different (<R1/L11, S1/L21, PR, PX> - <R/L1, S/L2, T/L3, U, V, W, a screw for earthing (grounding)>). For the 00760 or more,
screw sizes are different. (<R/L1, S/L2, T/L3, U, V, W> - < a screw for earthing (grounding)>)
