Title: a new problem one of many
Post by: maciek on April 24, 2017, 08:59:52 PM

so i have a electro mechanical clutch unit that spins at 500 rpm when i send a signal to clutch coil it actuates and clutch engages which turns the unit which cuts wire simple enough.i have a proximity sensor to see if it actually moved or got stuck and moved twice .
the no cut is easy but double cut it does not always work

At 500 RPM the double cuts occur 2 milliseconds apart. Verify that the input point response time and the scan time of the program allow for distinguishing this interval.
