I/O Functions

*1. For information on operation of I/O functions, refer to pages page 22 to page 25.

*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.)

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

Operating Procedures (Tachometer Function)

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.

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.

Minimum reset signal width

Output delay time

1 ms

0.8 to 1.2 ms

20 ms

15 to 25 ms

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.)

• 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.
