Precautions for Correct Use
 Tighten the terminal block screws to the torque of 1.5 N•m (M5).
 If the torque for terminal block screws exceeds 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 1.4 to 1.6 N•m (M5).
 Never connect an External Regeneration Resistor between the B1 and N (NC) terminals
OMNUC G5-SERIES AC SERVOMOTOR AND SERVO DRIVE USER'S MANUAL
Name
R88D-KT@H (7.5 kW): 3-phase 200 to 230 VAC (170 to 253 V) 50/
60 Hz
280 to 325 VDC (238 to 357 VDC)
Connect an External Regeneration Resistor between B1 and B2.
These are the output terminals to the Servomotor.
Be sure to wire them correctly.

These terminals are used to control the MC for externally connected
dynamic brake resistance. The output contact specifications are
1 A max. at 300 VAC/100 VDC max. Connect them if required.
Normally DB3 and DB4 are connected. When using an externally
connected Dynamic Brake Resistor, remove the short bar from
between DB3 and DB4.
This is the ground terminal. Ground to 100 Ω or less.
