Motion Configuration Instructions 
Configuration instructions include all motion instructions that are used to 
establish and apply servo configuration parameters to an axis. This group of 
instructions includes hookup diagnostic instructions and tuning instructions.   
Use the motion configuration instructions to tune an axis and run diagnostics 
tests for the servo system. The tests include: 
•  A motor encoder hookup test 
•  An encoder hookup test 
•  A marker test 
•  A commutation test (for PM motors only) 
•  Determine important motor parameters

Tags used for the motion control attribute of instructions should only be used once. Re-use of 
the motion control tag in other instructions can cause unintended operation. This may result in 
damage to equipment or personal injury.
