Part 1 Installation
4. Noise Control Measures and Grounding
(1) Wiring and power source
PE on the power terminal block is used for protective grounding. Provide Class D grounding from this
terminal.
Use a grounding cable with a wire size of 1.0 mm
2
(#AWG17) or more, which should not be smaller
than the AC power cable.
[1] 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’s Technical Service Section or Sales Engineering Section.
(2) Noise-elimination grounding
Provide dedicated grounding for the FG and PE.
