Explanation:
Repositioning of block processing is presently not possible. A mode change cannot take place.
The 2nd parameter describes which action should be used to perform repositioning.
Reaction:
Alarm display.
Remedy:
Let the program continue to a repositioned NC block or modify part program.
Programm
continuation:
Clear alarm with the Delete key or NC START.

[Channel %1: ] Action %2<ALNX> is not allowed due to a pending alarm
Parameters:
%1 = Channel number
%2 = Action number/action name
Explanation:
This action cannot be performed due to an alarm, or the channel is in the fault condition.
Reaction:
Alarm display.
Remedy:
Press the RESET key.
Programm
continuation:
Clear alarm with the Delete key or NC START.
16920
[Channel %1: ] Action %2<ALNX> is already active
Parameters:
%1 = Channel number
%2 = Action number/action name
Explanation:
An identical action is still being processed.
Reaction:
Alarm display.
Remedy:
Wait until the previous procedure has been terminated and then repeat the operation.
Programm
continuation:
Clear alarm with the Delete key or NC START.
16922
[Channel %1: ] Subprograms: action %2<ALNX> maximum nesting depth exceeded
Parameters:
%1 = Channel number
%2 = Action number/action name
Explanation:
Various actions can cause the current procedure to be interrupted. Depending on the action, asynchronous subroutines
are activated. These asynchronous subroutines can be interrupted in the same manner as user programs. Unlimited
nesting depth is not possible for asynchronous subroutines due to memory limitations.
Example: An interrupt interrupts the current program processing. Other interrupts with higher priorities interrupt processing
of the previously activated asynchronous subroutines.
Possible actions are: DryRunOn/Off, DecodeSingleBlockOn, delete distance-to-go, interrupts .....
Reaction:
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy:
Do not trigger the event on this block.
Programm
continuation:
Clear alarm with the RESET key. Restart part program
16923
[Channel %1: ] Program control: action %2<ALNX> not allowed in the current state
Parameters:
%1 = Channel number
%2 = Action number/action name
Explanation:
The current processing cannot be stopped since a preprocessing process is active.
This applies, for example, to the loading of machine data, and in block searches until the search target is found.
Reaction:
Interface signals are set.
Alarm display.
Remedy:
Cancel by pressing RESET!
