8.6.5 Function
1. Counter mode
a. High Speed counter module can count High Speed pulses which cannot be processed
by CPU module’s counter instructions (CTU, CTD, CTUD, etc.), up to binary value of 32
bits (-2,147,483,648 ~ 2,147,483,647).
b. Available input mode is 1-phase input or 2-phase input
c. Count increasing/decreasing methods are as follows;
i. 1-phase input :
I.
Increasing/decreasing count operation by program setting
II. Increasing/decreasing count operation by B-phase input signal
ii. 2-phase input : setting by difference in phase between A-phase and B-phase
d. Auxiliary modes are as follows
i. Count Latch
e. Input mode
i. 1-phase count mode
I.
Increasing/decreasing count operation by program setting
a. 1-phase 1-input 1-multiplication
i. A-phase input pulse is counted at rising and
increasing/decreasing will be decided by the program.
