through using environment
1) Usage
Input signal status affects the credibility of system in where noise occurs frequently or
pulse width of input signal affects as a crucial factor. In this case, the user sets up the
proper input on/off delay time, then the trouble by miss operation of input signal may be
prevented because the signal which is shorter than set up value is not adopted.
2) Operation
The narrower width pulse than input filter time is not considered as input signal
3) Using method
(1) Click twice the basic parameter on the project window of KGLWIN.
(2) The value of filter can be set up as one of 1ms unit to the Input Filter Time of the
basic parameter window. (Input Filter Time is set up as default value of 10ms)
(3) Set up Input Filter Time is conformed to all input.
