Hi,
I have a Micrologix 1500bxb set up to run a servo for a press feeder. Basically, a limit switch(XIO)on the press causes the rung which the PTO is on to go from false to true and the servo feed starts. When PTO is done, it latches the press down. A timer unlatches it and it goes up and the cycle repeats automatically from there.
It works ok, but I need to delay the start of the PTO after the false to true rung transition(press cycle). I'm having a hard time configuring any kind of delay that will operate automatically and continually after first cycle.
Do you have any tips for accomplishing this? Maybe using a mask or STI? If so, please include a sample. I've attached my program. Feel free to modify for me.
Thank You, Lou
