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 drive without fail.
⚫
The wiring should be connected after servo drive and servo motor installed correctly

● Grounding: The grounding wire should be as thick as possible, 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 drive.
● Install fuse (NFB) promptly to cut off the external power supply if drive error occurs.
(2) The control signal CN1
● 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 10 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 resistor
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 drive. At this time, the energy feedback is
first received by the capacitor in the drive, 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
The recommended regenerative resistance specifications for the iSV2 series are as follows:
