Other Precautions

(1) Attachment Methods of Ferrite Cores
(2) Recommended Ferrite Core
Linear servomotor main circuit cable
(3) Recommended Noise Filter and Surge Absorber
For more information on recommended noise filters and surge absorbers, refer to
Series Product Catalog. (KAEP S800000 42)
(4) Fixing the Cable
Fix and ground the cable shield using a piece of conductive metal.
• Example of Cable Clamp
Host controller side
(5) Shield Box
A shield box, which is a closed metallic enclosure, is effective as reinforced shielding
against electromagnetic interference (EMI) from SERVOPACKs. The structure of the
box should allow the main body, door, and cooling unit to be attached to the ground.
The box opening should be as small as possible.
Note: Do not connect the digital operator and the analog monitor cable to the SERVOPACK
during operations. Connect them only when the machinery is stopped during mainte-
nance.
