■2-phase pulse input
The count method can be selected from 1 multiple, 2 multiples, and 4 multiples. The phase difference between the A phase
pulse and B phase pulse determines whether the pulses are counted up or down. The following figure shows the relationship
between the A phase pulse input and B phase pulse input.
