12.11.2.1
The ENDAT encoder system is an encoder with an absolute encoder section and an
incremental encoder section.
The control requests the encoder absolute value from the encoder after every POWER ON or
deselection of "Parking" and then calculates the machine absolute position. After that, the
control uses only the incremental encoder section with amplified sine/cosine output signals.
To determine the absolute information several binary-coded scale tracks are evaluated. With
the EQN 1325, the tracks are on several gear-coupled discs and on the linear scale with the
linear encoder LC 181.
