Two types of motion faults exist.
Type Description Example
Errors Do not impact controller operation
Should be correct to optimize execution time and ensure
program accuracy
A Motion Axis Move (MAM) instruction with
a parameter out of range
Minor/Major Caused by a problem with the servo loop
Can shutdown the controller if you do not correct the fault
condition
The application exceeded the servo loop
position error tolerance
Understanding Errors
Executing a motion instruction within an application program can generate
errors. The MOTION_INSTRUCTION tag has a field that contains the error
code (any number from 1 to 23 depending on the error).
