Wiring Precautions
The electronic control devices may malfunction due to noise from nearby
power supply lines, external loads, or other sources.
Malfunctions caused by noise can be troublesome because it can be difficult
to recreate the situation and to identify the noise source.
Use the following methods to eliminate malfunctions due to noise and improve
the system's reliability.
• When selecting wiring components, use wires or cables that meet or
exceed the specifications listed in the Servo Drive User's Manual.
• Wire the control lines (communications lines, external I/O signal lines,
etc.) separately from the power lines (AC power supply lines and motor
power lines). Do not wire these lines together in the same duct or bundle
them together.
• Use shielded cables for the control lines.
• Use the specified special cables to connect the PCU and Servo Drives.
• Always connect surge suppressors to nearby inductive loads (relays or
solenoids).
