Need More Help..........
Hi,
I need some more help again. I installed a 5000ppr Automation Direct encoder and have a problem getting an output flag to set in the Ultra when the speed of the flying shear actuator is equal to the auxiliary encoder. I've read about using an STI to convert the HSC into RPM within the ML1500, but I don't see how to apply it to my application.
The problem I'm having is this, I setup a 36" part length at about 30FPM. When I increased the speed of the rollform to 40FPM, the parts were shearing too long, about 3". I reset to 30FPM and tried 48" part lengths, these were shearing too short, about 3" also.
Right now I have it set up so when the HSC reaches the HPR, it starts the Ultra following till the UpToSpeed flag is set which causes the shear to cycle. I know this is all wrong because it's a constant RPM and not a "speed matching" or "position matching" flag being set.
What's the trick/s here to getting this to be precise and reliable?
Thank You,
Lou
