I/O Functions

Using as a Counter *1

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.

• The following table shows the delay from when the reset signal is input until the output is turned OFF. (Reference values)

Minimum reset signal width	Output delay time
1 ms	0.8 to 1.2 ms
20 ms	15 to 25 ms

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.

Panel Cutouts

Panel cutouts are as shown below. (according to DIN43700).

Note: 1. The mounting panel thickness should be 1 to 5 mm. Note: 2. To allow easier operation, it is recommended that Adapters be mounted so that the gap between sides with hooks is at least 15 mm (i.e., with the panel cutouts separated by at least 60 mm). Note: 3. It is possible to horizontally mount Timers side by side. Attach the Flush Mounting Adapters so that the surfaces without hooks are on the sides of the Timers. If they are mounted side-byside, water-resistance will be lost.
