The same signals (high-active) of each drive or drive group are logically linked by means of
AND operation. The different signals selected via p10039 are logically OR'ed. Result of
these logic operations is the "Safe State" for each drive group. You will find details in the
SINAMICS S120/S150 List Manual in function diagrams 2901 (Basic Functions) and 2906
(Extended Functions).
Each F-DO supports the interconnection of up to 6 signals by way of indexing (p10042[0...5]
to p10045[0...5]) and their output as logical AND operation.
