Chapter 8 Built-in High-speed Counter Function
8.2 Installation and Wiring
8.2.1 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 for filter.
▶ Connect A -phase only for 1-phase input.
▶ Connect A -phase and B-phase for 2-phase input.
8.2.2 Example of wiring
(1) In case of pulse generator (encoder) is voltage output type
