Step 2: Travel to zero mark
The behavior of the axis in step 2 depends on whether a reference cam is available:
•
Reference cam available:
When the converter reaches the reference cam, the
axis accelerates
in the opposite direction to the start
direction
, to the "approach velocity zero mark".
•
No reference cam is available: The converter accelerates the axis
in the start direction
to the "approach velocity zero mark".
