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 workpiece then the limit is reached.
If several workpieces are made on several toolholders/spindles simultaneously, it is possible to note
18100 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 MMC, 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 machine data $MN_MM_NUM_CUTTING_EDGES_IN_TOA (can only be performed with the
necessary access rights!).
Program Clear alarm with the Delete key or NC START.
Continuation:
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
deactivated. 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
monitoring? 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
$MN_MM_TOOL_MANAGEMENT_MASK, $MC_TOOL_MANAGEMENT_MASK
- Check whether the required option is set accordingly.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
6432 Function not executable. No tool assigned to tool holder/spindle
Parameters: %1 = Channel ID
Definitions: When an attempt is made to perform an operation that requires a tool to be located on the spindle.
This can be the quantity monitoring function, for example.
Reaction: Interface signals are set.
Alarm display.
Remedy: Select another function, another toolholder/spindle, position tool on toolholder/spindle.
Program Clear alarm with the Delete key or NC START.
