(b) CW/CCW pulse input
For CW/CCW pulse input, pulses can be counted up with the phase A pulse input and counted down with the
phase B pulse input.
The following figure shows the relationship between phase A pulse input and phase B pulse input.
(c) 2-phase pulse input
For 2-phase pulse input, multiple of 1, multiple of 2, or multiple of 4 can be selected as a counting method.
The phase difference between phase A pulses and phase B pulses determines whether the pulses are counted
up or down.
The following figure shows the relationship between phase A pulse input and phase B pulse input.
