Chapter 2 Basic Unit Specification
4. High speed input
2-24
4 High speed counter
4.1 General characteristic of high speed counter
Input requirements:
A. the duty circle for the input form should be 1:1;
B. Low voltage level should be less than 9V.
C. The respnding frequency of the high speed counter differs from high /low voltage level.

The above requirement should be met, or the responding frequency will be less or the counting
data would be wrong.
