Power supply
circuit
Reads counting signals
Increment, decrement, command, individual, and quadrature inputs accepted.
Reads CP1 count signals with CP1 input and CP2 count signals with CP2 input.
Increment signals can be input.
Resets present value and outputs (OUT2 when using the batch counter). (See note 1.)
Counting cannot be performed during reset/reset 1 input.
The reset indicator is lit during reset input.
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.
Does not operate (Not used).
Resets the total count value.
Holds the total count value at 0 during total reset input.
Resets the batch count value and batch output (OUT1).
Holds the batch count value at 0 during reset 2 input.
Resets the CP2 present value.
Counting for CP2 input cannot be performed during reset 2 input.
(See note.)
Reads counting signals. (CP2 input is not available.)
Holds the measurement value and outputs. (Reset 2 input is not available.)
The reset indicator is lit during hold.
Outputs signals according to the specified output mode when a set value is reached.
