thick. Plain stitch
copper wires are recommended.
If an EMI lter is used, observe the precautions as described in section 3.6.2.
2) Grounding
To prevent potential magnetic interference, conduct grounding correctly according to the
following instructions.
a. Grounding the motor housing
Connect the grounding terminal of the servo motor to the PE terminal of the servo drive
and ground the PE terminal, to reduce potential magnetic interference.
b. Grounding the shield of the power cable
Ground both ends of the shield or metal conduit of the motor main circuit. Crimping is
preferable to ensure good contact.
c. Grounding the servo drive
Ground the PE terminal of the servo drive properly. The screw of this terminal must be
xed solidly to ensure good contact.
