Channel %1 subprograms: action %2 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 possi-
ble 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.
- Alarm display.
- Interface signals are set.
- NC Stop on alarm.
Initiate a block change and repeat the action.
Clear alarm with the Delete key or NC START.
Channel %1 conflict when activating user data type %2
%1 = Channel number
%2 = Data type
The "activate user data" function (PI service _N_SETUDT) modifies a data block (tool off-
set, settable zero offset or base frame) which is also written by the NC blocks in prepara-
tion.
In the event of a conflict, the value entered by the MMC is reset.
Parameter %2 specifies which data block is affected:
1: Active tool offset
2: Base frame
3: Active zero offset
- Alarm display.
Check the inputs on the MMC and repeat if necessary.
Clear alarm with the Delete key or NC START.
Channel %1 interrupt treatment: action %2<ALNX> not allowed in the current state
%1 = Channel ID
%2 = Action number/action name
If a temporary standstill has occurred because of a Reorg event across block boundaries,
it is possible that a block without Reorg capability has been loaded. In this situation, it is
unfortunately necessary to abort the Reorg event handling! Reorg events are, e.g. abort
subprogram, delete distance-to-go and interrupts.
- Alarm display.
- Interface signals are set.
- NC Start disable in this channel.
- NC Stop on alarm.
Abort program with the RESET key.
Clear alarm with the RESET key. Restart part program
Channel %1 interrupt treatment: action %2<ALNX> not possible due to stop
%1 = Channel ID
%2 = Action number/action name
