Block %2 Motion Synchronous Action: Nesting Depth Exceeded; Block %2 Motion Synchronous Action: Command Not Executable; Block %2 Motion Synchronous Action: Internal Error %3 - Siemens Sinamics S120 Diagnostic Manual

NCK alarms
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Correct error in expression.
Program Clear alarm with the RESET key. Restart part program
Continuation:
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 Clear alarm with the RESET key. Restart part program
Continuation:
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.
