*1 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 or higher. It assumes a surrounding air temperature of 50°C or lower and in-enclosure wiring.
*2 It is the gauge of the cable with continuous maximum permissible temperature of 90°C (THHN cable). It assumes a surrounding air temperature
of 40°C or lower and in-enclosure wiring.

*3 The recommended cable size is that of the cable (XLPE cable) with continuous maximum permissible temperature of 90°C. It assumes a
surrounding air temperature of 40°C or lower and in-enclosure wiring.
(Selection example mainly for use in Europe.)
*4 The screw size for terminals R/L1, S/L2, T/L3, U, V, W, P/+, N/-, and the earthing (grounding) terminal are shown.
Screw size for earthing (grounding) is indicated in parentheses.
The line voltage drop can be calculated by the following formula:
× wire resistance [mΩ/m] × wiring distance [m] × current [A]
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.
NOTE
• Tighten the terminal screw to the specified torque.
A screw that has been tightened too loosely can cause a short circuit or malfunction.
A screw that has been tightened too tightly can cause a short circuit or malfunction due to the unit breakage.
• Use crimp terminals with insulation sleeves to wire the power supply and motor.
