When using the phase B pulse input or CH Count down command (RY22, RY3A) for 1-phase pulse input, turn off the
unused signals.
When the phase B pulse input or CH Count down command (RY22, RY3A) is on, countdown is performed with the phase
A pulse input.
(a) 1-phase pulse input
For 1-phase pulse input, multiple of 1 or multiple of 2 can be selected as a counting method.
The following figure shows the relationship between phase A pulse input and phase B pulse input or CH
Count down command (RY22, RY3A).
