Definitions: This alarm is activated via MD 27880 PART_COUNTER, bit 1:
The number of counted workpieces ($AC_ACTUAL_PARTS or $AC_SPECIAL_PARTS)
is equal or already larger than the programmed value for the number of required work-
pieces ($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

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
Reactions: - Interpreter stop
- NC Start disable in this channel.
- Interface signals are set.

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 Con- Clear alarm with the RESET key. Restart part program
