Chapter 7 Usage of Various Functions

7.1.2. Pulse Catch Function
In the main unit, 4(economic type) or 8(standard type) points of pulse catch input contact points are internalized. Through using
this contact point, short pulse signal short can be taken which can not be executed by general digital input.
1) Usage
When narrow width of pulse signal is input, a trouble occurs which can not be detected by general digital input, so the
operation does not perform as user's intention. But in this case through pulse catch function even narrow interval of pulse
signal as 10
㎲
min. can be detected.
2) Minimum input pulse width.

scan1
CPU senses input when pulse signal, min. 10
㎲
, is input, then saves the status.
scan2
used to turn on the region of input image
scan3
used to turn off the region of input image
4) using method
(1) click twice the basic parameter on the project window of KGLMIN
(2) Select no. to use for pulse catch input of the basic parameter window.
For details of KGLWIN refers to the manual.
