I've gone the hal route, as it seems the quickest solution for my meager need. I've cascaded two one shots, with an and gate to and the oneshot output with a 'spindle at speed' signal so the oneshots don't pump lube when the machine is idle.
But I need a suggestion on getting the works rolling - I'm having trouble using the 'spindle-at-speed' signal (which I have as feedback from my VFD) to trigger the oneshots. My HAL code: setp oneshot.0.width 5 setp oneshot.1.width 5 setp oneshot.1.falling 1 net spindle-at-speed and2.0.in0 net oneshot_midpoint <= oneshot.0.out net oneshot_midpoint => oneshot.1.in net oneshot_result <= oneshot.1.out net oneshot_result => oneshot.0.in net oneshot_midpoint => and2.0.in1 net way_lube <= and2.0.out net way_lube => hm2_7i43.0.7i64.0.0.digout.06.out # Relay On Mon, Feb 11, 2013 at 9:04 AM, Dave <[email protected]> wrote: > I was going to say the same thing..
