Appendix H User-defined Function Block Motion Instructions
• Three types of move operations (Set_MoveMethod = 2,3,4) are performed as shown.
Define 'Indexing Coordinate':
• Rotate Positive or Rotate Negative or Rotate Shortest Path.
The Rotary move types are used to provide a way to index while observing the natural
rollover of the feedback device. For example, if the motor could only index positive, the
Rotary Positive is used. When the feedback device transitions through its natural
unwind (typically 2.1 billion counts), the movements always index positive.
IMPORTANT At this time, the Kinetix 5100 drive does not have a user defined Unwind
function. The rotary selections in this UDFB do not refer to user defined
rotary axis types.
