Channel %1 subprograms: action %2<ALNX> maximum nesting depth exceeded
Parameters: %1 = Channel number
%2 = Action number/action name
Definitions: 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 subrou-
tines.
Possible actions are: DryRunOn/Off, DecodeSingleBlockOn, delete distance-to-go, inter-
rupts .....
Reactions: - 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.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
