Chapter Three Wiring
●
Personnel involved in wiring or examination must possess sufficient abilities in this task.
● Wiring and examination must be conducted 5 minutes after the power is off for preventing electric
shock.
●
The wires must be connected according to terminal voltage and electrode to prevent the
equipment from being damaged or personnel from being hurt.
● The drive unit and servo motor must have good ground contact.
3.1 Standard Wiring
External connection of the drive unit is related to the control modes.

Power Terminal TB
z Wire cross-sectional area: Terminals of R, S, T, PE, U, V and W have an area
1.5mm
2
(AWG14-16) and more while terminals of r and t have an area 1.0 mm
2
(AWG16-18) and more.
z Grounding: the grounding wire shall be as thick as possible. The servo driver and
motor has ground contact at the point of PE terminal with a grounding resistance
less than 100
Ω .
z Terminal connection adopts SVM2-4 pre-insulation cold pressing terminal. The
connection must be fastened.
z It is recommended to supply power with three-phase isolating transformer, which
will reduce the possibility of electric shock.
z It is recommended that the power supply gives power through noise filter for
enhancing anti-jamming ability.
z
Please install non-fuse breaker (NFB) in order to cut off external power supply
when the driver breaks down.
（ 2 ） CN2Contrl Signal CN1 and Feedback Signal CN2
z
Wire material selecting: employ shielding cable (best with inter-twisted shielding
cable), the cross-section area of the core shall be 0.12mm 2 (AWG24-26) and more.
The shielding layer shall be connected with FG terminal.
z Wire and cable length: wire and cable shall be as short as possible; control signal
CN1 shall not be longer than 3 meters while the feedback signal CN2 cable shall not
be longer than 20 meters.
z Wire laying: Wire shall be laid far away from the power circuit to prevent jamming.
