Definitions: In calculating an arithmetic expression for a motion synchronous action, an overflow has
occurred (e.g. division by zero).
Reactions: - 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.
Reactions: - 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)
Reactions: - 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 diagnostics purposes. Please make a note and contact the manufacturer.
