Posted by Ann Marie Rynning on 1/20/2001 6:18 PM EST:
: our team has the pneumatics and the compressor set up and running. however, due to the way that the programming is, once the compressor is at 110 psi, it starts going on and off every second or so to maintain that pressure. do you know how I could modify the program so that this doesn't happen? is there a way to make the compressor stay on for a minimum amount of time instead of it turning on and off rapidly?
: thank you.
We found that if you can keep track of the number of actuator strokes, you can figure out how many strokes you can go before the accumulator pressure drops below 60psi. Use a multiplier for the bigger actuators. You'll only need a nibble of computer space since the counter isn't going to be very big. About 5 in our case. Hope it helps. See you at Nationals.
