(2) Precautions Regarding Wiring Method
1) Use a twisted cable for connection to the power supply.
2) To reduce the interference to each other, have the I/O line, communication and encoder
lines, power and driving supply lines separate from each other.
(3) Noise Sources and Elimination
Carry out noise elimination measures for power devices
on the same power path and in the same equipment.
The following are examples of measures to eliminate
noise sources:
1) AC solenoid valves, magnet switches and relays
[Measure] Install a Surge Absorber parallel with
the coil.
2) DC solenoid valves, magnet switches and relays
[Measure] Install a diode parallel with the coil.
Use a DC relay with a built-in diode.
Do not share the ground wire with or connect
to other equipment. Ground each controller.
