Chapter 7 Built-in High-speed Counter Function
XBC E-Type Main Unit 7-7 Ver. 1
iii. CW(Clockwise)/CCW(Counter Clockwise) operation mode
A-phase input pulse counts at rising, or B-phase input pulse counts at rising.
Increasing operation executed when B-phase input pulse is Low with A-phase
input pulse at rising, and Decreasing operation executed when A-phase input
pulse is Low with B-phase input pulse at rising.
Increasing/Decreasing
classification
A-phase input pulse High A-phase input pulse Low
B-phase input pulse High -
decreasing count
B-phase input pulse Low Increasing count -
