We have a project with a couple different fairly simple positioning tasks. Speeds are fairly slow and positioning doesn't need to be super accurate.
One is a mechanism raised and lowered by a ball screw and gearbox. The mechanism needs to be set to multiple positions. The second is a rotating table driven by a gearbox. The only position we need here is the "home" position so the loading mechanism can line up properly with the table.
A couple options we've looked at:
1. Servo - seems like overkill
2. PF527 w/ absolute encoder
3. PF525 w/ absolute encoder
4. PF525 w/ incremental encoder and home switch
#2 seems like maybe the best option, although the one we're least familiar with. Can/should the encoder be wired through the VFD? Or does it need to go to the PLC (Compactlogix)?
Any advantage to #3 or #4?
