If STOP C has been triggered, this can have several reasons (depending on the configuration):
1. The safe speed monitoring has been triggered (MD 1361: $MD_SAFE_VELO_STOP_MODE (SG-
specific stop reaction) or MD 1363: $MD_SAFE_VELO_STOP_REACTION (SG-specific stop
reaction) (840D as of SW4.2)).
2. The safe end-position monitoring has been triggered (MD 1362: $MD_SAFE_POS_STOP_MODE
(safe end position stop reaction)).
The alarm indicates the initiation of a "deceleration at current limit" and the internal activation of "safe
standstill".
