2-phase 2-input
The wiring examples in this section use the following settings. When settings other than those in the table are used, use the
examples shown in the following figures as references for wiring.
CH to be used
CH2 (CPU module) or CH10 (high-
speed pulse input/output module)
The settings of the high-speed counters are set by using the parameter settings of the engineering tool.
For details, refer to MELSEC iQ-F FX5 User's Manual (Application).
