Explanation: 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: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Modify part program.
Programm Clear alarm with the RESET key. Restart part program
continuation:
21800 [Channel %1: ] Workpiece setpoint %2 reached
Parameters: %1 = Channel number
%2 = Workpiece setpoint
Explanation: This alarm is activated via MD27880 $MC_PART_COUNTER, bit 1: The number of counted workpieces
($AC_ACTUAL_PARTS or $AC_SPECIAL_PARTS) is equal or already greater than the programmed value for the number
of required workpieces ($AC_REQUIRED_PARTS). At the same time, the channel VDI signal "Workpiece setpoint
reached" is output. The value for the number of counted workpieces ($AC_ACTUAL_PARTS) is reset, while the value of
$AC_SPECIAL_PARTS is retained.
Note:
The setpoint/actual comparisons of the workpieces are only made after an NC start
under the condition that $AC_REQUIRED_PARTS > 0. If $AC_REQUIRED_PARTS
has a negative value, all workpiece counts activated through MD27880 $MC_PART_COUNTER are frozen at the values
they have reached,
and the nominal/actual comparison is discontinued.
Reaction: NC not ready.
Interface signals are set.
Alarm display.
Remedy: No program interrupt. Delete alarm display.
Programm Clear alarm with the Delete key or NC START.
continuation:
22000 [Channel %1: ] Block %2 Spindle %3 Gear stage change in %4 not possible
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Spindle number
%4 = Gear stage
Explanation: 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: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
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.
Programm Clear alarm with the RESET key. Restart part program
