    Using an encoder to control a VFD.

    I need to use a rotary encoder to control the speed of a VFD, so if the line speed varies then the VFD also changes. I have no experience of this. Usually I use Rexroth drives (not Indramat). Can these use an encoder easily enough? Or can you recommend one and an encoder please! Thanks.
