Overview of Alarms
- Alarm display.
Remedy: Program an executable NC block between the previous and the current NC block.
Example:
N10 SETM.
N15 STOPRE ; insert executable NC block.
N20 CLEARM.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
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, 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.
Reactions: - 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 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
Reactions: - Alarm display.
Remedy: Check the inputs on the MMC 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.
Reactions: - NC Start disable in this channel.
- Interface signals are set.
