• Check whether the tool data are correctly defined. Has the correct T number been spec-
ified?
• Check whether the move command has been correctly parameterized. Is the desired
tool at the source location? Is the target location suitable for taking the tool?
• Check whether the tool has already been loaded (if the alarm occurs while loading the
tool).
Program Con- Clear alarm with the Delete key or NC START.
tinuation:

Channel %1 tool %2 cannot be placed in magazine %3 on location %4. Invalid defi-
nition of magazine!
Parameters: %1 = Channel ID
%2 = String (identifier)
%3 = Magazine number
%4 = Magazine location number
Definitions: The desired tool motion command - triggered from the MMC or PLC - is not possible. A
movement request was issued to put the tool in a location which does not satisfy the pre-
requisites for filling.
The following causes for the error are possible:
• Location is blocked or not free!
• Tool type does not match the location type!
• Tool possibly too large, adjacent locations are not free!
• If a tool is to be loaded or unloaded, the load/unload position must be of 'load location'
type.
• If a tool is to be loaded or unloaded, is the magazine in question linked to the
load/unload location?
See $TC_MDP1, $TC_MDP2.
Reactions: - NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
Remedy: • Check whether the magazine data have been defined correctly.
• Check whether there is still room in the magazine to add another tool; there may not be
due to operating procedures.
• Check whether a location type hierarchy is defined and whether it, for example, does not
allow insertion of a type 'A' tool in a free location with type 'B'.
• Check whether the magazine in question is linked to the load/unload location or whether
a distance has been defined.
• Check whether the load/unload position is of 'load location' type.

Program Con- Clear alarm with the Delete key or NC START.
tinuation:
6430
Workpiece counter: overflow in table of monitored cutting edges.
Definitions: No more cutting edges can be entered in the piece counter table. As many cutting edges
can be noted for the workpiece counter as are possible in total in the NCK. This means
that if for each tool each cutting edge in each TO unit is used precisely once for a work-
piece then the limit is reached.
If several workpieces are made on several toolholders/spindles simultaneously, it is pos-
sible to note 18100 MM_NUM_CUTTING_EDGES_IN_TOA cutting edges for the work-
piece counter for all of the workpieces.
