Appendix 9.5 Countermeasures for Wiring in Panel

Appendix 9.5 Countermeasures for Wiring in Panel
Cables act as antennas to propagate unnecessary noise, and thus must be appropriately shielded and
treated. The following countermeasures must be sufficiently considered for the cables (FCUA-R000
/FCUA-R211) that carry out high-speed communication.

Appendix 9.5.1 Precautions for wiring in panel

(1) If the cables are led unnecessary in the panel, they will pick up noise. Thus, keep the wiring
length as short as possible.

(2) Always connect the grounding wire to the FG terminal indicated on the device.
(3) Keep the distance between the drive line and encoder cable to the drive section motor as far
apart as possible when wiring.
(4) Do not lead the drive line around the panel without using a filter.
