5. Measures for Wiring in Panel

Cables act as antennas to propagate unnecessary noise, and thus must be appropriately shielded and

treated. The following measures must be sufficiently considered for the cables

(SH21/F010/FCUA-R211) that carry out high-speed communication.

5.1 Precautions for Wiring in Panel

(1) If the cables are led unnecessary in the panel, they will be contaminated by noise. Thus, keep the

device layout and 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 power cable and detector cable to the drive section motor as far

apart as possible when wiring.

(4) Do not lead the power wire around the panel without using a filter.
