Errors in Motion Control instructions
Description
Errors in Motion Control instructions (e.g. invalid parameter value setting) are indicated at
the "Error" and "ErrorID" output parameters.
Under the following conditions, "Error" = TRUE and "ErrorID" = 16#8xxx are indicated at the
Motion Control instruction:
●
Invalid status of the technology object, which prevents the execution of the job.
●
Invalid parameter assignment of the Motion Control instruction, which prevents the
execution of the job.
●
As a result of the alarm response for an error at the technology object.
Error indication
If an error occurs in a Motion Control instruction, the "Error" parameter shows the value
TRUE. The cause of the error can be found in the value of the ErrorID" parameter.
Jobs at the technology object are rejected when "Error" = TRUE. Running jobs are not
influenced by rejected jobs.
If "Error" = TRUE and "ErrorID" = 16#8001 are indicated during the job processing, then a
technology alarm has occurred. In this case, evaluate the indication of the technology alarm.
If "Error" = TRUE is displayed during the execution of a "MC_MoveJog" job, the axis is
braked and brought to a standstill. In this case, the deceleration configured with the
"MC_MoveJog" instruction takes effect.
Acknowledge errors
Acknowledging errors in Motion Control instructions is not required.
Restart a job after resolving the error.
Additional information
A list of the ErrorIDs can be found in the appendix, Error Detection (Page 386).
