Part 1 Installation
[2] Notes on wiring method
Use twisted cables for the AC power cable and 24-VDC external power cable. Wire the controller
cables separately from lines creating a strong electric field such as power circuit lines (by not
bundling them together or placing in the same cable duct).
If you wish to extend the motor cable or encoder cable beyond the length of each supplied cable,
please contact IAI.
(2) Noise-elimination grounding
Provide dedicated FG or PE grounding.
(3) Noise sources and noise elimination
There are many noise sources, but solenoid valves, magnet switches and relays are of particular
concern when building a system. Noise from these parts can be eliminated using the measures
specified below:
[1] AC solenoid valve, magnet switch, relay
Measure --- Install a surge absorber in parallel with the coil.
AC power source
Class D grounding
Metal enclosure
Connect the FG terminal
with the metal enclosure
using a cable of a
maximum allowable size
over the shortest distance.
Surge absorber
Point
Wire from each coil over the shortest distance.
Installing a surge killer on the terminal block,
etc., will be less effective because of a longer
distance from the coil.
