● It is recommended to install the drive to a conductive metal surface. Ensure the
whole conductive bottom of the drive is connected properly to the mounting face.
● Tighten the grounding screw with specified tightening torque to prevent the
protective grounding conductor from being secured improperly.
Single-drive grounding
Installation of an individual drive:

No.
Description
①
Input protection (fuse or circuit breaker) Connect the lower end of the
fuse to the filter.
②
Input power supply
③
Do not ground the DC bus terminal or the regenerative resistor terminal.
④
Connect the output PE terminal of the servo drive to the motor output
cable shield.
⑤
Connect the PE cable on the input power supply side to the input PE
terminal of the servo drive.
⑥ Ground the motor enclosure.
⑦
Three‑phase motor
Note: The main circuit terminal layout varies with different models and is subject to the
physical product.
