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.
Reaction: 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 Clear alarm with the RESET key. Restart part program
Continuation:
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 separate 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 executable 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.
Reaction: Correction block is reorganized.
Interpreter stop
Interface signals are set.
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 Clear alarm with NC START or RESET key and continue the program.
