*1 For the 55K 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. Assumes that the ambient temperature is 50°C or less and the wiring distance is 20m or less.
For the 75K 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. Assumes that the ambient temperature is 50°C or less and wiring is performed in an enclosure.
*2 For the 45K or less, the recommended cable size is that of the cable (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 20m or less.
For the 55K or more, the recommended cable size is that of the cable (THHN cable) with continuous maximum permissible temperature of 90°C.
Assumes that the ambient temperature is 40°C or less and wiring is performed in an enclosure.
(Selection example for use mainly in the United States.)
*3 For the 45K or less, the recommended cable size is that of the cable (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.
For the 55K or more, the recommended cable size is that of the cable (XLPE cable) with continuous maximum permissible temperature of 90°C.
Assumes that the ambient temperature is 40°C 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 110K and 132K, screw sizes are different (R/L1, S/L2, T/L3, U, V, W, a screw for earthing (grounding) - P/+ for option connection)
For the 160K or more, screw sizes are different. (R/L1, S/L2, T/L3, U, V, W - a screw for earthing (grounding))
The line voltage drop can be calculated by the following formula:
3 × 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.
CAUTION
· Tighten the terminal screw to the specified torque.
A screw that has been tighten too loosely can cause a short circuit or malfunction.
A screw that has been tighten too tightly can cause a short circuit or malfunction due to the unit breakage.
· Use crimping terminals with insulation sleeve to wire the power supply and motor.
