(2) Grounding for Noise Prevention
a. It is necessary to ground the controller to prevent noise, regardless of whether it is configured as a
100 or 200 VAC system.
b. General precautions on wiring method
Separate the wiring of the controller from strong electric lines such as the power circuit. (Do not bind
wires together, and do not place in the same duct.)
Consult IAI’s Technical Service Department or Sales Technology Department if you need longer
cables for motor or encoder wiring.
