Clear alarm with the RESET key. Restart part program
Axis %1 drive %2 safe end positions exceeded
%1 = Axis number
%2 = Drive number
The drive is disabled by the reaction configured in MD 1362:
$MD_SAFE_POS_STOP_MODE. At the end of the stop reaction, the drive remains under
control, the axis is monitored for SBH.
Request: In monitoring cycle.
The axis has exceeded the limit position which is entered in
• Modify MD 1334: $MD_SAFE_POS_LIMIT_PLUS[n] (upper limit for safe end position)
• Modify MD 1335: $MD_SAFE_POS_LIMIT_MINUS[n] (lower limit for safe end position)
- NC Start disable in this channel.
- NC Stop on alarm.
- Alarm display.
- Interface signals are set.
Please inform the authorized personnel/service department. If no obvious operator error
occurred: Check the input value of the machine data and check the SGEs: was the correct
one of 2 end positions selected? If the MDs and SGEs are o.k., check the machine for any
damage and rectify.
Clear alarm with the RESET key. Restart part program
Axis %1 drive %2 is not safely referenced
%1 = Axis number
%2 = Drive number
No stop reaction is initiated. The message will be present during enabling of the functions
SN/SE until the axis status "Axis safely referenced" has been reached.
Request: In monitoring cycle.
1) The axis is not referenced or
2) The user enable for this axis is missing or was canceled. This can occur, for example, if
the axis was moved after the machine was switched off and the standstill position which
was stored is therefore no longer correct.
This message prompts the user to confirm the actual position. To do this, you must deter-
mine the position, e.g. as follows:
• Measure the position.
• Move to a known position.
- Alarm display.
Please inform the authorized personnel/service department. If no safe automatic refer-
encing is possible, the user must confirm the new position via the soft key. This user con-
firmation marks this position as safe, that means the axis status "Axis safely referenced"
is reached.
Warning:
If the axis has not been safely referenced and the user has not confirmed, the following
applies:
• The safe cams are still active and not yet safe.
• The safe limit positions are not yet active.
Alarm display showing cause of alarm disappears. No further operator action
Axis %1 drive %2 test stop is running
%1 = Axis number
