General Mach Discussion / home/limit switch problems

« on: November 06, 2016, 12:11:10 PM »

Decided to go with PNP NO prox's for limit and home switch's. Using a C10 BOB, ive got the xyz+ wired together in parallel to one input, xyz- all have there own input but each switch is a shared limit/home switch. input resistor is set pull down. Powering the switch's with a 12vdc Omron power supply, 10kohm resistors between the prox signal cable and the input point. All in all these are working awful. In the diagnostic screen they flicker on and off, and I can change the rate of flicker by adjusting the debounce interval. with the debounce interval set to 50000, yes, you read that right, 50000, the flickering seems manageable. Thinking about abandoning the last 2 weekends of work and putting in dry contact micro switch's. wish I had a treid it before I ran all the cables in the cable track.
Whats the downside to having that high of debounce interval?
What am I doing wrong?
