Precautions
(1) Attachment Methods of Ferrite Cores
(2) Recommended Ferrite Core
∗
For details, refer to diagrams in
10.2.1 EMC Installation Conditions
.
(3) Fixing the Cable
Fix and ground the cable shield using a piece of conductive metal.
• Example of Cable Clamp
(4) 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 cool-
ing unit to be attached to the ground. The box opening should be as small as possible.
Note: Do not connect the analog monitor cable to the SERVOPACK during operations.
Connect them only when the machinery is stopped during maintenance.
