20145 [Channel %1: ] Block %2 motion synchronous action: arithmetic error
Parameters: %1 = Channel number
%2 = Block number
Definitions: 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.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
20146 [Channel %1: ] Block %2 motion synchronous action: nesting depth
exceeded
Parameters: %1 = Channel number
%2 = Block number
Definitions: 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.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
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 Con- Clear alarm with the RESET key. Restart part program
tinuation:
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 diag-
nostics 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.
