Overview of Alarms
NCK alarms
21760 Channel %1 block %2 too many auxiliary functions programmed
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The number of programmed auxiliary functions has exceeded the maximum permissible amount. This
alarm can occur in conjunction with motion synchronous actions: The maximum number of auxiliary
functions must not be exceeded in motion block and motion synchronous actions.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Modify part program.
Program Clear alarm with the RESET key. Restart part program
Continuation:
21800 Channel %1 workpiece setpoint %2 reached
Parameters: %1 = Channel number
%2 = Workpiece setpoint
Definitions: This alarm is activated via MD 27880 PART_COUNTER, bit 1:
The number of counted workpieces ($AC_ACTUAL_PARTS or $AC_SPECIAL_PARTS) is equal or
already larger than the programmed value for the number of required workpieces
($AC_REQUIRED_PARTS).
At the same time, the channel VDI signal "Workpiece setpoint reached" is output.
The value for the number of the counted workpieces ($AC_ACTUAL_PARTS) is reset while the value
of $AC_SPECIAL_PARTS remains.
Reaction: NC not ready.
Interface signals are set.
Alarm display.
Remedy: No program interrupt. Delete alarm display.
Program Clear alarm with the Delete key or NC START.
Continuation:
22000 Channel %1 block %3 spindle %2 gear stage change not possible
Parameters: %1 = Channel number
%2 = Spindle number
%3 = Block number, label
Definitions: A gear stage change for the spindle will not be possible, if:
- thread cutting (G33, G34, G35) is active
- the spindle is active as master or slave spindle in a coupling
- the spindle is being positioned
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: The gear stage is to be set prior to the corresponding machining step.
If it is necessary, however, to change the gear stage within one of the above mentioned functions, this
function must be switched off for the time of the gear stage change. Thread cutting is deselected with
G1; synchronous spindle coupling is switched off with COUPOF; the spindle positioning operation is
exited with M3, M4 or M5.
Program Clear alarm with the RESET key. Restart part program
