Greetings!
We have a small conveyor made up of metal bins that catch product with an indexing motion. It is controlled by an Ultra3000i indexing servo drive. Today, a technician told me that he has never seen the drvie fault, even when the conveyor gets in a serious bind, it just rips itself apart.
He asked me to try to limit the drive current so that it would fault rather than create so much damage. I found a cable and fired up the laptop with Ultraware, connected to the drive and found the only place I could adjust any current setting was under the "Faults" branch "user current limit". The value in the drive was 255 amps! The drive/motor tab showed a peak current limit of 32amps.
I monitored the drive in normal operation and found the peak current to be 9 amps. I set the user current limit to 15 amps for now. I am not sure if what I did will help. Apparently, the bins on this conveyor come loose and hang up on the frame at least once a week so I should find out soon enough.
Can anyone tell me if I adjusted the correct parameter?
Thanks,
Paul
