5) 2-phase Operation Mode (Multiplicate 4)
When Phase A pulse input leads Phase B pulse input, the counter performs increment count.
When the other leads the one, it performs decrement count.
The counting is performed when the Phase A and B pulse inputs rise or fall.
2.6.2 Comparison Signal Output
The counting module has the function of comparison output, which outputs the result of
magnitude comparison between the Current value (=current value) and a comparison value.
There are two outputs in the comparison output and they can be used separately.
The magnitude comparison mode can be set as shown in the below table.

0
No magnitude comparison is performed.

Always On
The results as shown above will be indicated on the OUT1 LED or OUT2 LED regardless of the
output. Output to the external terminal block is performed only when the output enable signal is
ON.
