### PRD

displays the absolute position feedback of the hardware feedback device (for both resolver and encoder based systems) in one mechanical motor revolution. PRD will increment from 0 to 65,535 throughout the course of one mechanical motor shaft revolution (360 degrees). The range of PRD will not change. Its resolution is dependent upon the feedback device resolution.

For resolver feedback systems PRD resolution is dependent upon the value of RDRES:
RDRES = 12, resolution of PRD = 16.
RDRES = 14, resolution of PRD = 4.
RDRES = 16, resolution of PRD = 1.
For encoder-based systems, until the encoder has been initialized, PRD will be uninitialized and its value will not be useful or meaningful. For information on encoder initialization requirements according to the type of encoder, see MENCTYPE, ENCSTART, INITMODE, ENCINIT, and ENCINITST.
