7.5.3.4 Serial:EnDat2.2
Heidenhain encoders with an EnDat 2.2 interface have a serial communication channel
via which the servo drive can communicate with the encoder. This channel is used for the
purely digital transfer of the position value from the encoder. In addition, it is possible to
access the type plate of the encoder to read out certain characteristics such as the line
count, for example. As a result, the line count does not need to be parameterised in the
case of EnDat 2.2 encoders.
The EEPROM, which is often included in this type of encoder, can be used for saving and
loading parameters in the servo drive (see section 7.5.3.8 Storing parameters in the
encoder on page 148).
