I/O Functions

Using as a Counter *1

Inputs	CP1, CP2	(1) All Modes Except for Dual Counter Mode Reads count signals. Increment, decrement, up/down (command, individual, or quadrature) inputs can be used. (2) Dual Counter Mode Reads CP1 count signals on CP1 input and CP2 count signals on CP2 input. Increment signals can be used.
	Reset or Reset 1	(1) All Modes Except for Dual Counter Mode Resets present value and outputs (OUT2 when using the batch counter). *2 Counting cannot be performed while resetting or when reset 1 input is ON. The reset indicator is lit while the reset input is ON. (2) Dual Counter Mode Resets the CP1 present value to 0. Counting the CP1 input cannot be performed while the reset 1 input is ON. The reset indicator is lit while the reset 1 input is ON.
	Total Reset or Reset 2	The reset operation depends on the selected function. *3
Outputs	OUT1, 2	When the corresponding set value is reached, signals are output according to the designated output mode.

*1. Refer to Data Sheet for information on the operation of input and output functions.
*2. In increment mode or increment/decrement mode, the present value returns to 0; in decrement mode, the present
       value returns to the set value with 1-stage models, and returns to set value 2 with 2-stage models.
*3. The reset indicator will not be lit when the total reset or reset 2 input is ON.

Function	Reset operation
1-stage/2-stage preset counter	Does not operate (Not used).
Total and preset counter	Resets the total count value. Holds the total count value at 0 while the total reset input is ON.
Batch counter	Resets the batch count value and batch output (OUT1). Holds the batch count value at 0 while the reset 2 input is ON.
Dual counter	Resets the CP2 present value. Counting for CP2 input is disabled while the reset 2 input is ON.

Using as a Tachometer

Inputs	CP1, CP2	Reads counting signals. (CP2 input is not available.)
	Reset 1, Reset 2	Holds the measurement value and outputs. (Reset 2 input is not available.) The reset indicator is lit during hold.
Outputs	OUT1, 2	Outputs signals according to the specified output mode when a set value is reached.

Using as a Counter or Tachometer

Key protection input	Prohibits using the keys on the front panel. Set the key protection level in function selection mode. Key protection is enable by short-circuited key protection terminals.
