● Grounding the noise filter inside the cabinet
If the noise filter and the servo drive are installed in the same cabinet, fix the noise filter and the servo drive
on the same metal plate. Make sure the contact part is in good conductive condition, and ground the metal
plate properly.

3.9 Precautions of Using Cables
1. Do not bend or apply tension to cables. The core wire of a signal cable is only 0.2 or 0.3 mm in diameter
and easily broken. Handle the cables carefully.
2. In scenarios where cables need to be moved, use flexible cables. Common cables are easily damaged
after being bent for a long time. Cables configured together with low power servo motors cannot be used
for movement.
3. If cable protection chain is used, make sure that:
● the bending radius of the cable must be at least 10 times the diameter of the cable;
● do not fix or bundle the cables inside the cable protection chain. You can bundle them at both ends of
the cable protection chain;
● cables must not be wound or warped;
● space factor inside the cable protection chain must not exceed 60%;
● do not mix cables of great difference in size together as thick cables may crush thin cables. If you need
to use them together, place a spacer plate to separate them.
