Remedy: Please inform the authorized personnel/service department. The user must check the
cause and initiate the corresponding measures.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
300910
Axis %1 drive %2 stop E triggered
Parameters: %1 = Axis number
%2 = Drive number
Definitions: The drive ws stopped by the NC with STOP E. At the end of the stop reaction, the drive
remains under control, the axis is monitored for SBH.
Request: In monitoring cycle.
If STOP E has been triggered, this can have several reasons (depending on the configu-
ration):
1. The safe speed monitoring has been triggered (MD 1361:
$MD_SAFE_VELO_STOP_MODE (SG-specific stop reaction).
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 an "extended stop and retract" in the NC or "LIFT-
FAST-ASUP" (840D) and the internal activation of "safe standstill" in the NC and drive.
Reactions: - 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 Con- Clear alarm with the RESET key. Restart part program
tinuation:
300911
Axis %1 drive %2 error in one monitoring channel
Parameters: %1 = NC axis number
%2 = Drive number
Definitions: The mutual comparison of the two monitoring channels has found a difference between
input data or results of the monitoring operations. One of the monitors no longer functions
reliably, i.e. safe operation is no longer possible.
Reactions: - Alarm display.
Remedy: Please inform the authorized personnel/service department.
Find the difference between the monitoring channels. The error code indicating the cause
is displayed as follows:
• On the 840D it is output in the alarm text.
• On the 840C MD 301: diagnostics for STOP F
• On the 611D MD 1395: $MD_SAFE_STOP_F_DIAGNOSIS (diagnostics for STOP F)
You can find the meaning of the error code as follows:
• On the 840D: description of alarm 27001
• On the 840C: description of alarms 1336* / 2097*
A possible cause is that the safety-related machine data are no longer identical or that the
SGEs do not have the same level (recalibrate or check in the SI service display). If no
error of this type is apparent, an error may have occurred in the CPU, e.g. a "flipped"
memory cell. This error can be temporary (in this case it can be eliminated by a POWER
ON) or permanent (if it occurs again after POWER ON replace the hardware).
