Incremental encoders have a track with equidistant division and a defined number of increments as well as a zero track with a reference mark. The reference mark is assigned to exactly one increment of the incremental track and therefore has a clear assignment to the mechanical system of the machine.
Immediately after switching on the control unit, absolute encoders return the absolute position value without the machine moving. The absolute position is determined via optoelectronic scanning of several code tracks
Single-turn encoders sense the absolute position within one revolution, while multiturn encoders also code the number of revolutions.
The transmission of the position information to the control unit with PROFIBUS reduces the wiring complexity. The encoders can be parameterized and support the isochronous mode with data exchange broadcast.
