*1 For the FR-F740-55K or less, the recommended cable size is that of the cable (e.g. HIV cable (600V class 2 vinyl-insulated cable)) with continuous
maximum permissible temperature of 75°C. Assumes that the surrounding air temperature is 50°C or less and the wiring distance is 20m or less.
For the FR-F740-75K or more, the recommended cable size is that of the cable (e.g. LMFC (heat resistant flexible cross-linked polyethylene insulated
cable)) with continuous maximum permissible temperature of 90°C. Assumes that the surrounding air temperature is 50°C or less and wiring is performed
in an enclosure.
*2 For the FR-F740-45K or less, the recommended cable size is that of the cable (THHW cable) with continuous maximum permissible temperature of 75°C.
Assumes that the surrounding air temperature is 40°C or less and the wiring distance is 20m or less.
For the FR-F740-55K or more, the recommended cable size is that of the cable (THHN cable) with continuous maximum permissible temperature of 90°C.
Assumes that the surrounding air 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 FR-F740-45K or less, the recommended cable size is that of the cable (PVC cable) with continuous maximum permissible temperature of 70°C.
Assumes that the surrounding air temperature is 40°C or less and the wiring distance is 20m or less.
For the FR-F740-55K or more, the recommended cable size is that of the cable (XLPE cable) with continuous maximum permissible temperature of 90°C.
Assumes that the surrounding air temperature is 40°C or less and wiring is performed in an enclosure.
(Selection example for use mainly in the 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).
A screw for earthing (grounding) of the 185K or more is indicated in ( ).
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.
