SIMODRIVE alarms
300908 Axis %1 drive %2 stop C triggered
Parameters: %1 = Axis number
%2 = Drive number
Definitions: 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".
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. The user must check the cause and
initiate the corresponding measures.
Program Clear alarm with the RESET key. Restart part program

%2 = Drive number
Definitions: 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.
Reaction: NC Start disable in this channel.
