Oh well, been looking at megasquirt, was hoping to use some of my ab stuff and also something familiar. Thanks
-
Does anyone know if a plc would be fast enough to control fuel injection/ignition for a car?
-
Thanks guest, works great.

Anyone know of a way of getting a mircrologix 1500 to ramp down gradually from one set point to another within an adjustable time? Thanks
-
I have a micrologix 1500 with combo analog in and out with an lpvt on a cylinder for position and a proportional valve for "pressure" Is it possible to control the speed using feedback from input and send volts out that constantly is correcting itself to maintain a certain speed"Closed loop?" I know you can get velocity mods for other controllers, but are not available on micros. Could I use PID? Thanks Doug

That would be great. I'm going to control my robot with the AB, I install on this press. Robot controller is shot.

You guys are great. I hope someone asks an easy question one day, so I can answer it while you guys are asleep

I know what you mean. We have been converting thermoplastic injection presses to thermoset. That's one of the main reasons for changing the controls. Thermoset molding needs additional sequences, degas, gate cutting off ejector system, stuffer control, etc, that original equipment didn't have. I do have a question though. Does it increase or decrease response time having multiple ladder files, or is it written like that to save a lot of time scrolling up and down when troubleshooting and changing program?

Chris This was exactly what I was hoping for. I see it's a verticle/shuttle press, but still very similar. I can learn a lot from this. Thank you so much.

Thanks for the reply. Yes I have been there. Guess I was greedy"lazy?" and was hoping for an actual Inj press program example. Will look at brickyard and try to generate intelligent questions Thanks again

I've installed several plc's, micrologixs 1200 an 1500's in older injection molding presses in my shop replacing relay logic. I've used the same program as a base line and changed it to adapt to different machines particulars. After recently finding this site, I realize what an infant I am to programming. Does anyone have any programs I can see to compare to mine. I recently started using analog inputs and outs for position and pressure. Thank you in advance Doug
