Hi Everyone;
ElevMike told me to look here for help with this issue that I posted on the AD forum:
I am trying to feed a length of product through a punch which cuts it to length. I have a DO-06-DD1-D PLC with a H0-CTRIO controlling a STP-DRV-4035 stepper drive, STP-MTR-34066 motor, & TRD-GK360-RZD quad encoder. The stepper turns a roller and the encoder. There are sensors on the infeed and outfeed of the punch. I can get the PLC to eject the material if it's in the machine at startup, and I can get it to feed and trim cut the material. But I can't seem to get it to feed the material to length. I am wondering what would be the best mode to do this: dynamic positioning, or run to position? The cut length varies and I'll be inputting the length in ASCII from a PC which is hooked into port #2. I am not working, on that part yet, I'm just trying to get the piece to feed to a preset length. I have DS5 software.
ElevMike said that there was an example here that would help me, he said to search under "learning by doing" but i can't seem to find it.
Any help would be appreciated. I'm not looking for someone to write my code, just a push in the right direction. I'm starting to push up against a deadline on this project and would like to get it done.
Thanks!
