(BML SL1-ALZ0-U1ZZ-AU1L-S284/KA_ _)
With the analog sine and cosine signals +A (+sin), −A (−
sin), +B (+cos) and −B (−cos), the controller evaluates the
difference in signal amplitudes and, from the signals,
interpolates the precise position within a period. For a
movement over several periods, the controller also counts
the number of periods. The period is 2 mm.
For correct function, the sine signal +A (+sin) −
(−A (−sin)) and the cosine signal +B (+cos) − (−B
(−cos)) must be evaluated depending on the
direction.
An exact description and suggestion for an
evaluation circuit can be found in the document

In case of an error, the
process data is 0x7FFFFFFF.
This parameter contains the
last valid position value
before any error.
