Planner Counts
This attribute value is the Motion Planner generated actual position in planner
counts. The internal 64-bit signed integer representation of actual position is
range limited by Motion Task to a signed 32-bit integer.

Interpret the Attribute Tables
These are the basic motion scaling configuration attributes associated with a
Motion Control Axis. These attributes are involved in conversion between
position, speed, and acceleration expressed in Motion Counts and Motion Units,
and the user-defined Position Unit of the axis. The motion scaling function is also
involved in conversion of Motion Counts to/from Feedback Counts, and Motion
Units to/from Feedback Units.

The Motion Scaling Configuration attribute determines whether the scaling
function is performed by the controller or the drive. The Control Scaling selection
configures the control system to perform the scaling calculations in the controller.
In this mode, the controller interacts with the drive in terms of Feedback Counts
or Motor Units, hence no scaling operations are required by the drive. Also, in
Control Scaling mode the controller is responsible for Position Unwind (Cyclic
Unwind for device axis objects) operations associated with Cyclic Travel Mode
(Cyclic Unwind Control for device axis objects).
The Drive Scaling selection configures the control system to perform the scaling
calculations in the drive device. In this mode, the controller interacts with the
drive in terms of Motion Counts or Motion Units and the drive is responsible for
conversion to equivalent Feedback Counts and Motor Units. Also, in Drive
