Ϩʳ When D1022=K4, the timing diagram of one double frequency will be

as follows:

X10

A-phase (X0)

B-phase (X1)

Counting

Ϩʳ When D1022=other value, the timing diagram of tw0 double frequency

will be as follows:

C251

 When M0 = ON, High speed counter C251 counts as follow:

Count value Contact status Y10

101 ON ON

 When high-speed counter C251’ s value changes from (199 to 200) or

from (201 to 200), the contact of C251 will be ON and Y10 will be ON.

However, there will be scan time delay.
