Grounding
To prevent potential magnetic interference, conduct grounding correctly according to the following instruc-
tions.
■ Grounding the servo motor housing
Connect the grounding terminal of the servo motor to the PE terminal of the servo drive and correctly ground
the PE terminal, to reduce potential magnetic interference.
■ Grounding the shield of the encoder cable
Tie the shield of the motor encoder cable to ground at both ends.
3.8.2 Using a Noise Filter
To prevent interference from power cables and reduce impact of the servo drive to other sensitive devices,
installanoiselterontheinputsideofthepowersupplyaccordingtotheinputcurrent.Inaddition,install
anoiselteronthepowersupplylineofperipheraldevicesifnecessary.Observethefollowingprecautions
wheninstallingandwiringthenoiseltertoavoidinuencingitsactualeffect.
● Donotputtheinputandoutputwiresofthenoiselerinthesameductorbundlethemtogether.
