I/O Functions

Using as a Counter *1

Inputs	CP1, CP2	(1) All Modes Except for Dual Counter Mode and Twin Counter Mode • Reads count signals. • Increment, decrement, up/down (command, individual, or quadrature) inputs can be used. (2) Dual Counter Mode or Twin 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 and Twin 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 or Twin 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.
Twin counter	• Resets the CP1 present value and output 1 when the CP1 present value is displayed. • Resets the CP2 present value and output 2 when the CP2 present value is displayed.

Using as a Tachometer

Inputs	CP1, CP2	Reads counting signals. (The CP2 input can be used when the input mode is not 1-input mode.)
Inputs	Reset 1, Reset 2	• Holds the measurement value and outputs. (The reset 2 input can be used when the input mode is 2-input independent measurement.) • Functions as a hold input. The measurement value (displayed value) and the outputs are held while the RST Key on the front panel is pressed. • The reset indicator is lit when the value is being held.
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.
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.
