3.4.3.1 Functional Specification

Incremental value
The incremental sin-cos signals are safety-assessed. The
monitoring of the unit circle allows achieving a diagnostic cov-
erage of 99 %. The function can be examined at any time.
This means that, for an encoder resolution of 2048 sine-co-
sine periods, the validity can be checked by the encoder eval-
uation unit 2048 times per revolution. With a tolerance of the
sin²(x) + cos²(x) function of ± 0.5, the max. possible error path
will be 10 % of a signal period (36° electrically).
Typical limits and tolerances see chapter Technical Data
[} 42].

The sine-cosine signal alone does not allow realizing abso-
lute safety sub-functions and a safe rotation direction can
achieve at the maximum SIL2. Additional signal paths are re-
quired to be able to use both to a full extent up to SIL3.

3.4.4 Safety Assessment

You will find the characteristic safety values to be used for
your own determination of the safety level of your machine in
chapter Technical Data [} 41].
