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

High-speed counter

Examples of wiring for high-speed counters are shown below.
When capturing pulses of a response frequency of 50 to 100 kHz, refer to Page 94 In the case of capturing high-speed
pulses.
For details on the high-speed counters, refer to MELSEC iQ-F FX5 User's Manual (Application).
For the programs, refer to MELSEC iQ-F FX5 Programming Manual (Instructions, Standard Functions/Function Blocks).
1-phase 1-input (S/W)
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
CH1 (CPU module)
The settings of the high-speed counters are set by using the parameter settings of the engineering tool.
