(a) 1-phase pulse input
The count method can be selected from 1 multiple and 2 multiples.
The following figure shows the relationship between phase A pulse input and phase B pulse input or CH
Down count command (Y3, YB).
The following figure shows the relationship between phase A pulse input and phase B pulse input or CH
Down count command (Y3, YB).
(b) CW/CCW pulse input
Pulses can be counted up with the A phase pulse input and counted down with the B phase pulse input.
The following figure shows the relationship between A phase pulse input and B phase pulse input.
The following figure shows the relationship between A phase pulse input and B phase pulse input.
(c) 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 A phase pulse input and B phase pulse input.
The phase difference between the A phase pulse and B phase pulse determines whether the pulses are
