525 Programmable Motion Controller
Encoder Feedback
The 525 PMC utilizes an xe "ENCODERS:Incremental Encoder" incremental
encoder as the feedback device from the motor. The type of encoder used must have
two complimentary channels electrically spaced 90 from each other. These encoder
channels are usually designated as CHA and CHB. To fully utilize the motion
controller, the encoder must have a third complimentary channel that has a once
per revolution output called Mark, or Index.
Emerson Motion Control can provide two encoder configurations for use with the
525 PMC.
