pulse input modes
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).
2-phase multiple of 1
For counting up Counts on the rising edge (
↑
) of
φ
A while
φ
B is off.
For counting
down
Counts on the falling edge (
↓
) of
φ
A while
φ
B is off.
2-phase multiple of 2
For counting up
Counts on the rising edge ( ↑ ) of φ A while φ B is off.
Counts on the falling edge ( ↓ ) of φ A while φ B is on.
For counting
down
Counts on the rising edge ( ↑ ) of φ A while φ B is on.
Counts on the falling edge ( ↓ ) of φ A while φ B is off.
2-phase multiple of 4
For counting up
