D2 Series Servo Drive User Manual Wiring
HIWIN MIKROSYSTEM CORP. 4-5
(6) When servo motor is grounded through a machine, switching noise current may flow out from the
servo drive main circuit with the stray capacitance of the servo motor. To avoid the above situation,
connect the frame or ground terminal of the servo motor to the ground terminal of the servo drive.
Then ground the ground terminal of the servo drive. When linear motor is used, both the forcer
and stator must be grounded.
(7) When control signal cable is interfered, connect its shield to its connector shell. Then perform
grounding.
4.1.2 CN1 power
The pin assignment of CN1 for frame A-C models is different with that for the frame D model. Check the
pin assignment for each model before use. Descriptions of CN1 power wiring include: single/three-phase
power input, motor power output (frame A-C), regenerative resistor wiring, single-phase control power
input, and DC reactor wiring (frame D).
4.1.2.1 Power wiring
Before connecting the main circuit of drive, ensure that the drive is properly grounded. Frame D model is
only allowed connecting three-phase 200 - 240 Vac.
(1) Frame A-C
Connector model: Wago 721-112/026-000 (female).
