Warning
Warning
The workers of participation in wiring or checking must possess sufficient ability do this job.
The wiring and check must be going with power off after five minutes.
Caution
Ground the earth terminal of the motor and driver without fail.
The wiring should be connected after servo driver and servo motor installed correctly

● Grounding: The grounding wire should be as thick as possible, drive servo motor the PE terminal
point ground, ground resistance <100 Ω.
●Use noise filter to remove external noise from the power lines and reduce an effect of the noise
generated by the servo driver.
● Install fuse (NFB) promptly to cut off the external power supply if driver error occurs.
(2) The control signal CN1 feedback signal CN2
● Diameter: shielded cable (twisting shield cable is better), the diameter ≥ 0.14mm
2
(AWG24-26),
the shield should be connected to FG terminal.
● Length of line: cable length should be as short as possible and control CN1 cable is no more than
3 meters, the CN2 cable length of the feedback signal is no more than 20 meters.
● Wiring: be away from the wiring of power line, to prevent interference input.
●Install a surge absorbing element for the relevant inductive element (coil),: DC coil should be in
parallel connection with freewheeling diode reversely; AC coil should be in parallel connection
with RC snubber circuit.

Regenerative resister
When the torque of the motor is opposite to the direction of rotation (common scenarios such
as deceleration, vertical axis descent, etc.), energy will feedback from the load to the driver. At this
time, the energy feedback is first received by the capacitor in the driver, which makes the voltage of
the capacitor rise. When it rises to a certain voltage value, the excess energy needs to be consumed
by the regenerative resistance
