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 electri
shock.
●The wires must be connected according to terminal voltage and electrode to prevent th
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.
1） Position Control Mode
Fig. 3.1 shows standard wiring for the position control mode.
2） Speed Control Mode:
Fig. 3.2 shows the standard wiring for the speed control mode.
3） Wire Distributing
（1） 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 100Ω.
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.
