High-Speed Counter - Mitsubishi Electric MELSEC iQ-F Series User Manual

High-speed counter

Wiring examples for high-speed counters are shown below.
When capturing pulses of a response frequency of 50 to 100kHz for the FX5S/FX5UJ CPU modules or 50 to 200kHz for the
FX5U/FX5UC CPU modules, refer to the following.
Page 181 When capturing high-speed pulses
1-phase 1-input (software)
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.
