Overview of Alarms
NCK alarms
22068 Channel %1 block %2 tool management: no tool available in tool group
%3
Parameters: %1 = Channel number
%2 = Block number, label
%3 = String (identifier)
Definitions: The specified tool group does not contain a tool which is ready for use and could be used for tool
change. It is possible that all of the tools in question have been set to the 'Disabled' state by the tool
monitoring function. The alarm can occur for example in conjunction with the alarm 14710 (error on
INIT block generation). In this specific situation, NCK attempts to replace the disabled tool located on
the spindle with an available replacement tool (which does not exist in this error condition).
The user must resolve this conflict, for example, by removing the tool located on the spindle from the
spindle by issuing a movement command (e.g. through MMC operation).
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: - Ensure that the specified tool group contains a tool that is ready for use when tool change is
requested.
- This can be achieved, for example, by replacing disabled tools, or
- by releasing a disabled tool manually.
- If an alarm occurs on programming TCA: Has the duplo number been programmed >0?
- Check whether the tool data are correctly defined. Have all intended tools in the group been
defined/loaded with the specified identifier?
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
22069 Channel %1 block %2 tool management: No tool available in tool group
%3, program %4
Parameters: %1 = Channel number
%2 = Block number, label
%3 = String (identifier)
%4 = Program name
Definitions: The specified tool group does not contain a tool which is ready for use and could be used for tool
change. It is possible that all of the tools in question have been set to the 'Disabled' state by the tool
monitoring function. Parameter %4 = program name facilitates the identification of the program
containing the programming command (tool selection) that caused the error. This can be a
subprogram or cycle, etc., which can no longer be identified from the display. If the parameter is not
specified, it is the currently displayed program.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: - Ensure that the specified tool group contains a tool that is ready for use when tool change is
requested.
- This can be achieved, for example, by replacing disabled tools, or
- by releasing a disabled tool manually.
- Check whether the tool data are correctly defined. Have all intended tools in the group been defined
with the specified identifier and loaded?
Program Clear alarm with NC START or RESET key and continue the program.
