10912 Channel %1 block %2 preprocessing and main run might not be

synchronized

Parameters: %1 = channel number

%2 = block number, label

Definitions: The specified curve cannot be pre-calculated reliably. The reason for this is either that the axes

involved in the transformation are traversed as positioning axes or that a transformation pole is cir-

cumnavigated 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 pro-

gram 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 LookAhead 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-

tinuation:

Clear alarm with the Delete key or NC START.

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 Con-

tinuation:

Clear alarm with the Delete key or NC START.

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 causes could

be:

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..).

- Incorporation of the tool length compensation depends on the selected working plane (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 the part program.

Modify an incorrectly specified tool length compensation.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program
