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 possible to take over the velocity check into the main
run, part program processing is aborted.
Reaction: 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 Clear alarm with the Delete key or NC START.
Continuation:
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.
Reaction: Local alarm reaction.
Alarm display.
Remedy: No action is usually necessary. The alarm message indicates an error in the programming, however,
and this should be corrected.
Program Clear alarm with the Delete key or NC START.
Continuation:
10914 Movement not possible while transformation active - in channel %1,
block %2
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The machine kinematics does not allow the specified motion. Transformation-dependent error causes
can be in: TRANSMIT: A (circular) area exists around the pole, where positioning is not possible. The
area is caused by the fact that the tool reference point cannot be traversed as far as into the pole.
The area is defined by:
- the machine data ($MC_TRANSMIT_BASE_TOOL..)
- the active tool length compensation (see $TC_DP..). Whether the tool length compensation is
included in the calculation depends on the working plane selected (see G17,..).
- The machine stops before the faulty block.
Reaction: Interpreter stop
Local alarm reaction.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Modify part program. Change the incorrectly specified tool length compensation.
Program Clear alarm with the RESET key. Restart part program
