 Signal Width Greater Than 200
μ
s
If the signal width is greater than 200
μ
s, the input is detected when it turns ON and the input is
valid. Therefore, processing is based on the obtained latch data.
 Signal Width Less Than the Detected Width
If the signal width is less than the detected width, the input is not detected when it turns ON and the
input is not valid. Therefore, the obtained latch data is discarded and no processing is performed.
Precautions for Correct Use
Digital filtering is performed for 20 to 200 μ s for external inputs. Therefore signals with signal
widths of less than 200 μ s may not be detected. If you use a sensor with a short response time,
set an OFF delay timer for the output from the sensor or use another method to ensure a signal
width of at least 200
μ s for the external input.
