Absolut angle encoders and rotary encoders

Absolut angle encoders and rotary encoders require no previous traverse to provide the current position value. Singleturn encoders provide the current angular position value within one revolution, while multiturn encoders can distinguish between revolutions. Absolute angle encoders and rotary encoders from HEIDENHAIN provide the position values over an EnDat, SSI, PROFIBUS-DP or other serial data interface. The EnDat PROFIBUS-DP bidirectional interfaces enable automatic configuration of the higher-level electronics and provide moitoring and diagnostic functions. With programmable rotary encoders, the user can adjust various encoder functions and parameters from a PC with provided software.
