Main circuit terminal specifications
400V class (when input power supply is 440V based on the rated current for 110% overload for 1 minute)
The line voltage drop can be calculated by the following formula:
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.

*1 For the FR-F740-01160 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 (167°F). Assumes that the surrounding air temperature is 50°C (122°F) or less and the wiring distance is
20m (65.62feet) or less.
For the FR-F740-01800 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 (194°F). Assumes that the surrounding air temperature is 50°C (122°F)
or less and wiring is performed in an enclosure.
*2 For the FR-F740-00930 or less, the recommended cable size is that of the cable (THHW cable) with continuous maximum permissible temperature of
75°C (167°F). Assumes that the surrounding air temperature is 40°C (104°F) or less and the wiring distance is 20m (65.62feet) or less.
For the FR-F740-01160 or more, the recommended cable size is that of the cable (THHN cable) with continuous maximum permissible temperature of
90°C (194°F). Assumes that the surrounding air temperature is 40°C (104°F) or less and wiring is performed in an enclosure.
(Selection example for use mainly in the United States.)
*3 For the FR-F740-00930 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 surrounding air temperature is 40°C (104°F) or less and the wiring distance is 20m (65.62feet) or less.
For the FR-F740-01160 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 surrounding air temperature is 40°C (104°F) 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, P/+, N/-, P1, and a screw for earthing (grounding).
A screw for earthing (grounding) of the FR-F740-04320 or more is indicated in ( ).
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.
