Correct error in expression.
Clear alarm with the RESET key. Restart part program
Channel %1 block %2 motion synchronous action: nesting depth exceeded
%1 = Channel number
%2 = Block number
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.
- NC Start disable in this channel.
- NC Stop on alarm.
- Alarm display.
- Interface signals are set.
Correct error in expression.
Clear alarm with the RESET key. Restart part program
Channel %1 block %2 motion synchronous action: command not executable
%1 = Channel number
%2 = Block number
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)
- NC Start disable in this channel.
- NC Stop on alarm.
- Alarm display.
- Interface signals are set.
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.
Clear alarm with the RESET key. Restart part program
Channel %1 block %2 motion synchronous action: internal error %3
%1 = Channel number
%2 = Block number
%3 = Error code
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.
- NC Start disable in this channel.
- NC Stop on alarm.
- Alarm display.
- Interface signals are set.
Change synchronous action.
Clear alarm with the RESET key. Restart part program
