6.8 Examples of Wiring for Various Uses
High-speed counter
Examples of wiring for high-speed counters are shown below.
When capturing pulses of a response frequency of 50 to 200 kHz, refer to
Page 114 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.
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).
