SINUMERIK 802D sl, Diagnostics Manual, 06/2009

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

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 transfor-

mation 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 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 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-

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 [Channel %1: ] Block %2: movement not possible while transformation

active.

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 (MD24920 $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 Con-

tinuation:

Clear alarm with the RESET key. Restart part program

10930 [Channel %1: ] Block %2 interpolation type not allowed in stock removal

contour

Parameters: %1 = Channel number

%2 = Block number, label
