16931 [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, asyn-
chronous subroutines (ASUBs) are activated. These ASUBs can be interrupted in the same manner
as the user program. Unlimited nesting depth is not possible for ASUBs 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.
Reaction: Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Initiate a block change and repeat the action.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
16932 [Channel %1: ] Conflict when activating user data type %2
Parameters: %1 = Channel number
%2 = Data type
Definitions: The "activate user data" function (PI service _N_SETUDT) modifies a data block (tool offset, settable
zero offset or base frame) which is also written by the NC blocks in preparation.
In the event of a conflict, the value entered by the HMI is reset.
Parameter %2 specifies which data block is affected:
1: Active tool offset
2: Base frame
3: Active zero offset
Reaction: Alarm display.
Remedy: Check the inputs on the HMI and repeat if necessary.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
16933 [Channel %1: ] Interrupt treatment: action %2<ALNX> not allowed in the
current state
Parameters: %1 = Channel ID
%2 = Action number/action name
Definitions: 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.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Abort program with the RESET key.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
16934 [Channel %1: ] Interrupt treatment: action %2<ALNX> not possible due to
stop
Parameters: %1 = Channel ID
%2 = Action number/action name
