Program Continuation:

Axis %1 drive %2 stop C triggered

%1 = Axis number %2 = Drive number

The drive is disabled via STOP C. At the end of the stop reaction, the drive remains under control, the axis is monitored for SBH.

Request: In monitoring cycle.

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".
