New Machine Build- Encoder or Resolver

[Farmers Machine]

Building a new machine to flip green house plants in their container upside down. Have to use a stainless steel food grade servo. found one on Baldor web site. Sales man could not understand why I wanted an encoder instead of a resolver.
What is the difference in encoder and resolver?

the 2 options of encoder are 1000 and 2500 PPR.
does this mean with quadature you get 4000 and 10000 for accuracy?

Thank You

Depends on whether you are using a stand alone intelligent drive then it is up to whatever feedback the drive uses, if using a motion controller other than the dedicated drive, then it is whatever the controller will read, most commonly an encoder.
This is posted in the Camsoft forum and they use Galil, which will use 5v
differential encoder.
Galil multiply the quadrature pulses x 4.

Just curious - flipping green house plants in their container upside down?

What is the intended effect or purpose for doing that?

Had to sign a disclosure contract but it might have something to do with bio-medical research.

I thought it was maybe the same as the 'Seen on TV' upside down planters.
I tried one this year with a Tomato plant, it tried its hardest to grow upright, until gravity took over!
