10.3 Installation and Wiring
10.3.1 Precaution for wiring
Pay attention to the counteractions against wiring noise especially for High-speed pulse input
(1) Surely use twisted pair shielded cable, grounded with 3 class applied.
(2) Keep away from power cable or I/O line which may cause noise.
(3) Stabilized power should be used.
▶ Connect A-phase only for 1-phase input.
▶ Connect A-phase and B-phase for 2-phase input.
10.3.2 Example of wiring
