An error has occurred prior to reaching the assigned velocity
If an error occurs during execution of the Motion Control job before the assigned velocity has
been reached, this is indicated in the "Error" parameter with the value TRUE. The signal
status of the "Execute" parameter influences the indication duration in the "Error" parameter.
You set "Execute" after the occurrence of the error to
FALSE.
You set "Execute" before the occurrence of the error to
FALSE.
①
The job is started with a positive edge at the "Execute" parameter. Depending on the program, "Execute" can be reset
to the FALSE value while the job is still busy, or retain the TRUE value until the error has occurred.
②
While the job is active, the "Busy" parameter shows the value TRUE.
③
An error occurs during the execution of the job. When the error occurs, the "Busy" parameter changes to FALSE, and
the "Error" parameter to TRUE.
④
As long as the "Execute" parameter retains the value TRUE after completion of the job, the "Error" parameter also
retains the value TRUE.
⑤
If the "Execute" parameter has been set to FALSE before the job is aborted, then the "Error" parameter only shows
the value TRUE for one execution cycle.
