 Tighten the terminal block screws to the torque of 0.75 N•m (M4) or 1.5 N•m (M5).
 If the torque for terminal block screws exceeds 1.2 N•m (M4) or 2.0 N•m (M5), the terminal block
may be damaged.
 Tighten the fixing screw of the terminal block cover to the torque of 0.2 N•m (M3).
 Tighten the ground screws to the torque of 0.7 to 0.8 N•m (M4) or 1.4 to 1.6 N•m (M5).

Function
24 VDC ± 15%
Function
R88D-KT@F (3 to 5 kW):
3-phase 380 to 480 VAC (323 to 528 V) 50/60 Hz
Normally B2 and B3 are connected. Do not short B1 and B2.
Doing so may cause malfunctions.
If there is high regenerative energy, remove the short-circuit bar
between B2 and B3 and connect an External Regeneration
Resistor between B1 and B2.
Phase U These are the output terminals to the Servomotor.
Be sure to wire them correctly.
