SD710 Series Servo Drive User Manual Chapter 3 Wiring and Installation
34
Use thicker wire than 3.5 mm² (braided copper wire recommended) for the outer box connection for earthing, if possible.
When using the noise filter, observe the precautions described in "How to use the noise filter" below.
(2) Grounding Treatment
To avoid possible interference problems, ground as follows.
①
Grounding of servo motor casing
Please connect the ground terminal of the servo motor to the ground terminal PE of the servo driver and ground the PE
terminal reliably to reduce potential electromagnetic interference problems.
②
Grounding of encoder cable shield
Ground both ends of the shield of the motor encoder cable.
3.6.2 How to Use The Noise Filter
To prevent interference from the power supply line and weaken the influence of the Servo Drive on other sensitive
equipment, select the appropriate noise filter at the power supply input according to the input current. Also, install noise
filters at the power lines of peripheral devices as necessary. When installing and wiring the noise filter, observe the
following precautions to avoid weakening the actual use of the filter.
(1) Separate the noise filter input and output wiring, and do not group them in the same duct or bundle them together.
