Overview of Alarms
NCK alarms
20147 Channel %1 block %2 motion synchronous action: command not
executable
Parameters: %1 = Channel number
%2 = Block number
Definitions: One of the commands for the synchronous action block cannot be executed, e.g. it is not possible to
perform a Reset to the synchronous action.
Measurement level 2
- Embargo version does not allow measurement from a synchronized action
- MEASA was programmed in a synchronized action
- Measurement is already active
- Programming error (see alarm 21701)
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Change synchronous action.
Measurement level 2
Execute the measurement task from an NC program first, in order to improve the error diagnostics.
Only include it in the synchronized action when the first error-free run has been performed.
Program Clear alarm with the RESET key. Restart part program
Continuation:
20148 Channel %1 block %2 motion synchronous action: internal error %3
Parameters: %1 = Channel number
%2 = Block number
%3 = Error code
Definitions: An internal error has occurred during processing of a synchronous action. The error code is for
diagnostics purposes. Please make a note and contact the manufacturer.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Change synchronous action.
Program Clear alarm with the RESET key. Restart part program
Continuation:
20149 Channel %1 block %2 motion synchronous action: illegal index
Parameters: %1 = Channel number
%2 = Block number
Definitions: An invalid index was used for accessing a variable in the motion-synchronous action.
Example: ... DO $R[$AC_MARKER[1]] = 100
This error occurs if the value of marker 1 is greater than the maximum permissible R parameter
number.
PROFIBUS I/O:
An invalid slot / I/O area index was used while reading/writing data.
Cause:
1.: Slot / I/O area index >= max. number of available slot / I/O areas.
2.: Slot / I/O area index references a slot / I/O area that has not been configured.
3.: Slot / I/O area index references a slot / I/O area that has not been released for a system variable.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Use a valid index.
Program Clear alarm with the RESET key. Restart part program
Continuation:
