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-KN@F-ECT-R (3 to 5 kW):
3-phase 380 to 480 VAC (323 to 528 V) 50/60 Hz
Normally B2 and B3 are connected.
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.
Do not connect.
Phase U These are the output terminals to the Servomotor.
Be sure to wire them correctly.
