[Channel %1: ] Block %2 motion synchronous action: %3 arithmetic error
Parameters:
%1 = Channel number
%2 = Block number, line number
%3 = Synact ID
Explanation:
In calculating an arithmetic expression for a motion synchronous action, an overflow has occurred (e.g. division by zero).
Reaction:
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy:
Correct error in expression.
Programm
continuation:
Clear alarm with the RESET key. Restart part program
20146
[Channel %1: ] Block %2 motion synchronous action: %3 nesting depth exceeded
Parameters:
%1 = Channel number
%2 = Block number, line number
%3 = Synact ID
Explanation:
For calculating arithmetic expressions in motion synchronous blocks, an operand stack with a fixed set size is used. With
very complex expressions, this stack can overflow.
Reaction:
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy:
Correct error in expression.
Programm
continuation:
Clear alarm with the RESET key. Restart part program
20147
[Channel %1: ] Block %2 motion synchronous action: %3 command %4 not executable
Parameters:
%1 = Channel number
%2 = Block number, line number
%3 = Synact ID
%4 = Program command
Explanation:
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.
Programm
continuation:
Clear alarm with the RESET key. Restart part program
