4.1.2.5 Absolute encoders
Description of multiturn absolute encoders
This encoder outputs an absolute angular position between 0° and 360° in the specified
resolution. An internal measuring gearbox enables the encoder to differentiate between 4096
revolutions.
Description, absolute value singleturn
This encoder outputs an absolute angular position between 0° and 360° in the specified
resolution. Contrary to a multiturn absolute encoder, the encoder has no measuring gearbox
and can therefore only supply the position value within one revolution.
Function and technical data
● Angular measuring system for the commutation
● Speed actual value sensing
● For single-turn encoders: indirect measuring system for absolute position sensing within a
traversing range of 1 revolution
● For multi-turn encoders: indirect measuring system for sensing the absolute position
within a traversing range of 4096 revolutions
