Auto-correction speed is set to:

Long Correction (or Neg Long Override) Speed if the magnitude
of the current auto-correction distance-to-go is greater than the
specified Short Correction Distance,

Short Correction (or Neg Short Override) Speed percentage of the
current velocity of the Master Axis, if not.

The Neg Short Override and Neg Long Override settings let you
separately set speeds for negative direction auto-corrections.

A long correction move starts out at the long correction (or negative long
override) speed. When the auto-correction distance-to-go becomes less
than or equal to the specified short correction distance, the auto-
correction indexer accelerates or decelerates to the specified short
correction (or negative short override) speed. Acceleration (or
deceleration) occurs at the slave axis’ Maximum Acceleration (or
Maximum Deceleration) rate for the remainder of the correction.
