6.2.6.3 Position Measure - Pulse/Dir.
The Behavior of Pulse Direction Counter
Below figure shows the counter behavior of Pulse/Direction mode. Ch_A is a pulse
from encoder or any pulse generator. Ch_B is a digital input which indicates the
counter direction. When Ch_B is high, the counter value counts up with the Ch_A
input pulse (Rising Edge-Triggered); when Ch_B is low, the counter value counts
down with the Ch_A input pulse.
Blue is the 0x6000, 0x7000, 0x8000 parameters.
Red are the external signals.
The counter value and A, B signal input status can be read at below index:

6.2.6.4 Position Measure - CW/CCW
The Behavior of CW/CCW Counter
Below figure shows the counter behavior of CW/CCW mode. Ch_A and Ch_B are the
pulse from encoder or any pulse generator. The counter value counts up with the
pulse Ch_A and counts down with the pulse Ch_B.
