3.2 Wiring of Main Circuit Terminal Terminal layout of the main circuit and screw size are shown below. 3.2.1 Introduction to the main circuit (high voltage) terminal Table 3-1 Description of the main circuit terminal of the servo driver 3.2.2 Power wiring The servo driver may be subject to single-phase or three-phase power wiring. Single-phase power wiring is only permitted for models with the output current of 6.2A or below. ● Single-phase power wiring (applicable to rated output current of 6.2A or below) Single-phase Filter Servo driver Emergency stop Fig.

(EA190-0R9, 1R6 and 2R5 have neither wiring terminal D nor shorting wire.) P+, Common DC bus terminal The DC bus terminal of a servo driver can be connected to a common bus in case of multiple units connected in parallel. U, V, W Servo motor connecting terminal The connecting terminal of a servo motor connects to U, V and W phases of the motor. PE Grounding The two ground terminals are connected to the ground terminals of the power source and the motor.
