Channel %1 subprograms: action %2<ALNX> maximum nesting depth exceeded
%1 = Channel number
%2 = Action number/action name
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 the user program. Unlimited nesting depth is not possible for asynchronous subroutines due to memory limitations.
Example: In the case of an approach block in a repositioning procedure do not interrupt repeatedly, instead wait until processing is completed.
Possible actions are: mode change, SlashOn/Off, overstoring.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Initiate a block change and repeat the action.
Clear alarm with the Delete key or NC START.
