Inputs CP1, CP2 (1) In general (except for Dual Counter Mode)
Reads counting signals.
Increment, decrement, command, individual, and quadrature inputs accepted.
(2) When used as a dual counter or twin counter
Reads CP1 count signals with CP1 input and CP2 count signals with CP2 input.
Increment signals can be input.
Reset/reset 1 (1) In general (except for Dual Counter Mode)
Resets present value and outputs (OUT2 when using the batch counter) *2.
Counting cannot be performed during reset/reset 1 input.
Reset indicator is lit while reset input is ON.
(2) When used as a dual counter or twin counter.
Resets the CP1 present value (to 0).
Counting for 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 function depends on the selected configuration *3.
Outputs OUT1, OUT2 Outputs signals according to the specified output mode when a set value is reached.

*1. For information on operation of I/O functions, refer to Catalog.
*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. Reset operates as described in the following table. (The reset indicator will not be lit.)
Configuration Reset operation
1-stage/2-stage preset counter Does not operate (not used).
Total and preset counter Resets the total count value.
The total count value is held at 0 while the total reset input is ON.
Batch counter Resets the batch count value and batch output (OUT1).
The batch count value is held at 0 while the reset 2 input is ON.
Dual counter Resets the CP2 present value.
Counting for CP2 input cannot be performed while the reset 2 input is ON.
Twin counter Resets the CP2 present value.

Operating Procedures (Tachometer Function)

Inputs CP1, CP2 Reads counting signals. (The CP2 input can be used when the input mode is not 1-input
mode.)
Reset/reset 1 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, OUT2 Outputs signals according to the specified output mode when a set value is reached.
