CJ Position Control Units OPERATION MANUAL (CJ1W-NC214/234/414/434)
Wiring Precautions
Electronic control devices may cause position deviation or other malfunctions due to noise
from surrounding power supply lines, external loads, etc.
In many cases it is difficult to simulate malfunctions caused by noise, which means that it takes
time to identify their cause.
Implement the measures below to prevent malfunctions by noise and thereby enhance the
system reliability.
surge absorption diode whose dielectric strength is at least 5 times the circuit voltage.
when a source of high-frequency noise is located nearby, noise may enter the power supply line.
In this case, insert a noise filter in the input part of the power supply.
Ground to 100Ω or less, and use as thick a wire as possible which has a wire size of 1.25 mm
greater.
For the power line, we recommend using a twisted-pair cable.
Install a surge absorption diode or surge absorber as close as possible to the relay. Also, use a
When you share the power supply with an electrical welder or electrical discharge machine, or
Reference
For the sizes and materials for wiring, use wires or cables of the diameter which is specified in
the operation manual of your motor driver.
Wire the power lines (AC power supply, motor power line) separately from the control lines
(pulse output line, external I/O signal line). Do not place them in the same duct or bundle them
together.
Do not share the 24-VDC power supply for pulse output with any other I/O power supply.
For the control line, use a sheathed, shielded cable.
Be sure to install a surge absorber for any inductive load (such as a relay or solenoid).
