Overview of Alarms
- Alarm display.
- NC Stop on alarm.
- Channel not ready.
Remedy: Please inform the authorized personnel/service department. Check the safe standstill tol-
erance: does the value match the precision and control dynamics of the axis? If not,
increase the tolerance.
Program Con- Switch control OFF - ON.
tinuation:
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 configu-
ration):
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 activa-
tion of "safe standstill".
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:
300909
Axis %1 drive %2 stop D triggered
Parameters: %1 = Axis number
%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 configu-
ration):
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.
Reactions: - NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
