Remedy: Repeat action.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
16927
Channel %1 action %2<ALNX> at active interrupt treatment not allowed
Parameters: %1 = Channel number
%2 = Action number/action name
Definitions: This action may not be activated during interrupt processing (e.g. mode change).
Reactions: - Alarm display.
Remedy: Reset or wait until interrupt processing is terminated.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
16928
Channel %1 interrupt treatment: action %2<ALNX> not possible
Parameters: %1 = Channel number
%2 = Action number/action name
Definitions: A program interrupt has been activated in a non REORG capable block.
Examples of possible program interrupt in this case:
• Traversing to fixed stop
• VDI channel delete distance-to-go
• VDI axial delete distance-to-go
• Measuring
• Software limit
• Axis replacement
• Axis from correction
• Servo disable
• Gear stage change at actual gear stage unequal to setpoint gear stage.
The relevant block concerns a:
• Pick-up block during block search (excluding last pick-up block)
• Block in overstore interrupt.
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:
16930
Channel %1: preceding block and current block %2 must be separated through an
executable block
Parameters: %1 = Channel number
%2 = Block number
Definitions: The language functions WAITMC, SETM, CLEARM and MSG must be packed in sepa-
rate NC blocks due to the language definition. To avoid velocity drops, these blocks are
attached to the next NC block internally in the NCK (for MSG only in path control mode,
for WAITMC to the previous NC block). For this reason, there must always be an execut-
able block (not a calculation block) between the NC blocks. An executable NC block
always includes e.g. travel movements, a help function, Stopre, dwell time etc.
Reactions: - Correction block is reorganized.
- Interpreter stop
- Interface signals are set.
