*1.1-stage preset counter and total counter functionality.

*2.Do not use the output from an inverter as the power supply.The ripple must be 20% maximum for DC power.

*3.A response of 10 kHz (minimum pulse width: 0.05 ms) is possible if the response speed is 5 kHz and the 1-stage preset counter input mode is increment, decrement, or increment/decrement (command input).

*4.The display is lit only when the power is ON. Nothing is displayed when power is OFF.

A current of 0.15 A max. can be switched at 125 VDC (cosφ=1) and current of 0.1 A max. can be switched if L/R=7 ms. In both cases, a life of 100,000 operations can be expected.

I/O Functions

Using as a Counter *1

InputsCP1, 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 2The reset function depends on the selected configuration *3.
OutputsOUT1, OUT2Outputs signals according to the specified output mode when a set value is reached.

*1.For information on operation of I/O functions, refer to Data Sheet.

*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.)

ConfigurationReset operation
1-stage/2-stage preset counterDoes not operate (not used).
Total and preset counterResets the total count value.
The total count value is held at 0 while the total reset input is ON.
Batch counterResets the batch count value and batch output (OUT1).
The batch count value is held at 0 while the reset 2 input is ON.
Dual counterResets the CP2 present value.
Counting for CP2 input cannot be performed while the reset 2 input is ON.
Twin counterResets 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)

20 ms15 to 25 ms

Operating Procedures (Tachometer Function)

InputsCP1, CP2Reads counting signals. (The CP2 input can be used when the input mode is not 1-input mode.)
Reset/reset 1Holds the measurement value and outputs. (The reset 2 input can be used when the input mode is 2-input
independent measurement.)
The reset indicator is lit when the value is being held.
OutputsOUT1, OUT2Outputs signals according to the specified output mode when a set value is reached.
