37.5 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 (J210/J303) that carry out high-speed
communication.
37.5.1 Precautions for Wiring in Panel
(1) If the cables are led unnecessary in the panel, they will pick up noise. Pay attention to the device layout and wire
length so that the wiring length is 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 power supply wire around the panel without using a filter.
