3. Servo drive wiring precautions

Wiring precautions
3.1 Main wiring
1. Apply three-phase 220V AC mains through the NFB to the magnetic contactor, then connect
to the servo drive RST terminals. Consider installing a reactor and linear noise filter if the
local power supply quality is poor.
2. Connect the UVW terminals of the servo drive with the red, white and black cable lines of
the servomotor directly or via terminal board, on which the cable lines be secured with a
terminal plier and wrapped tightly to avoid incidental short-circuit, power interruption or
earth faults.
3. Make sure the cable lines are not damaged under stress. Be cautious of the cable wiring to
avoid as much as possible being subject to bending or tension.
4. If the servomotor is moving with the mechanism, arrange the bending section of the cable
line within the allowable curvature which is determined from the cable specification to assure
normal operation life.
5. Make sure the cable lines are not touched by sharp parts of the machine or pressed by any
heavy object.
6. Provide proper grounding wiring for the ground terminals of the servo drive and servomotor.
7. H1 and H2 are the thermostat terminals for the servomotor. Strictly forbid to short circuit
them with the machine bed or falsely connect with U V W E terminals.
8. After fastening the main terminal board, the ends of the wiring terminals can be bended up
to be kept away from the front nameplate as shown be
