Overview of Alarms
Remedy: Division of a block in several smaller ones often provides an improvement.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
10911
Channel %1 block %2 transformation prohibits to traverse the pole
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The given curve passes through the pole of the transformation.
Reactions: - Interpreter stop
- Local alarm reaction.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
Remedy: Modify part program.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
10912
Channel %1 block %2 preprocessing and main run might not be synchronized
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The preset positioning axis run cannot be accurately calculated beforehand. The reason
for this is either that the axes involved in the transformation are traversed as positioning
axes or that a transformation pole is circumnavigated too frequently by the curve. The
velocity check is performed starting from this block in the main run. It is more conservative
than with anticipated calculation. The LookAhead function is deactivated. If it is not possi-
ble to take over the velocity check into the main run, part program processing is aborted.
Reactions: - Alarm display.
Remedy: No action is usually necessary. The velocity control operates more effectively, however, if
the part program is modified.
• If a transformation pole is circumnavigated several times by the curve, it helps to split up
the block into smaller parts.
• If a positioning axis is the cause, you should check whether the axis can be traversed as
a path axis. The Look Ahead function remains deactivated until preprocessing can be
based on defined conditions again (e.g. as a result of change from JOG->AUTO, tool or
tool edge change).
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
10913
Channel %1 block %2 negative feed profile is ignored
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The given feed profile is in part negative. However, negative path feed is not allowed. The
feed profile is ignored. The specified feed block end value is taken when traversing over
the entire block.
Reactions: - Local alarm reaction.
- Alarm display.
Remedy: No action is usually necessary. The alarm message indicates an error in the program-
ming, however, and this should be corrected.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
10914
Movement not possible while transformation active - in channel %1, block %2
