Sinumerik Alarm 300909 Axis %1 drive %2 stop D triggered
%1 = Axis number
%2 = Drive number
The drive ws stopped by the NC with STOP D. At the end of the stop reaction, the drive remains under control, the axis is monitored for SBH. Request: In monitoring cycle. If STOP D 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 on path” in the NC and the internal activation of “safe standstill” in the NC and drive.
