Normal Mode
This section describes settings that become valid and functions that can be used when "Normal Mode" is selected for
"Operation Mode Setting". The following table shows I/O signals used in this mode.

Setting the high-speed counter function of other channel to the normal mode or PWM output mode is required.
*2
The signals can be used for other functions such as the general-purpose input except the interrupt input.
*3
Wiring the input signal is required depending on the selected counter function. When this signal is not required, it can be
used for other functions such as the general-purpose input and general-purpose output.
This section describes required settings and functions for each of the following item.
First of all, the setting item, "Counter Format", which is common for all items, is described.
Note that the explanations in this section assume use of CH1. For the special relay, special register, dedicated
instructions, error codes, and warning codes for CH2, refer to the following.
• Special relay and special register: Page 240, Section 8.9 (2)
• Dedicated instructions: Page 241, Section 8.10
• Error codes: Page 265, Section 8.12 (1)
• Warning codes: Page 266, Section 8.12 (2)
