Overview of Alarms
NCK alarms
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 oper-
ating procedures.
- Check whether a location type hierarchy is defined and whether it, for example, does not allow inser-
tion 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 possible to note
MD18100 $MN_MM_NUM_CUTTING_EDGES_IN_TOA cutting edges for the workpiece counter for
all of the workpieces.
If this alarm occurs, it means that cutting edges used subsequently are no longer quantity monitored
until the table has been emptied again, e.g. by means of the NC language command SETPIECE or
by the relevant job from HMI, PLC (PI service).
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: - Was decrementing of the piece counter forgotten? Then program SETPIECE in the part program, or
add the correct command in the PLC program.
- If the part program/PLC program is correct, then more memory should be set for tool cutting edges
via the MD18100 $MN_MM_NUM_CUTTING_EDGES_IN_TOA (can only be performed with the nec-
essary access rights!).
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
6431 [Channel %1: ] Block %2 Function not allowed. Tool
management/monitoring is not active.
Parameters: %1 = Channel ID
%2 = Block number, label
Definitions: Occurs when a data management function is called which is not available because ToolMan is deac-
tivated. For example, the language commands GETT, SETPIECE, GETSELT, NEWT, DELT.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: - Please inform the authorized personnel/service department.
- Make sure of how the NC is supposed to be configured! Is tool management or tool monitoring
needed but not activated?
- Are you using a part program that is meant for a numerical control with tool management/tool mon-
itoring? It is not possible to start this program on the numerical control without tool management/tool
monitoring. Either run the part program on the appropriate NC control or edit the part program.
- Activate tool management/tool monitoring by setting the appropriate machine data. See
MD18080$MN_MM_TOOL_MANAGEMENT_MASK,
MD20310$MC_TOOL_MANAGEMENT_MASK
- Check whether the required option is set accordingly.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
