I/O Functions
Using as a Counter
Note: 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.

Inputs CP1, CP2 • In general (except for dual counter mode)
Reads counting signals
Increment, decrement, command, individual, and quadrature inputs accepted.
• When used as a dual counter
Reads CP1 count signals with CP1 input and CP2 count signals with CP2 input.
Increment signals can be input.
Reset or Reset 1 • In general (except for dual counter mode)
Resets present value and outputs (OUT2 when using the batch counter). (See note.)
Counting cannot be performed during reset/reset 1 input.
The reset indicator is lit during reset input.
• When used as a dual counter
Resets the CP1 present value (to 0).
Counting for CP1 input cannot be performed during reset 1 input.
The reset indicator is lit during reset 1 input.
Total Reset or
Reset 2
• When used as a 1-stage/2-stage counter
Does not operate (Not used).
• When used as a total and preset counter
Resets the total count value.
Hold the total count value at 0 during total reset input.
• When used as a batch counter
Rest the batch count value and batch output (OUT1).
Holds the batch count value at 0 during reset 2 input.
• When used as a dual counter
Resets the CP2 present value.
Counting for CP2 input cannot be performed during reset 2 input.
Outputs OUT1, OUT2 Outputs take place according to designated output mode when corresponding preset is
reached.
Inputs CP1, CP2 Reads counting signals. (CP2 input is not used.)
Reset 1, Reset 2 Holds the measurement value and outputs. (Reset 2 input is not used.)
The reset indicator is lit during hold.
Outputs OUT1, OUT2 Outputs signals according to the specified output mode when a set value is reached.
