GetCommandedAcceleration returns the commanded acceleration value for the specified axis.
Commanded acceleration is the instantaneous acceleration value output by the trajectory
generator.
Scaling example: If a value of 114,688 is retrieved using this command then this corresponds to
114,688/ 65,536 = 1.750 counts/cycle2 acceleration value. See “SNAP-SCM-MCH16 Conversion
Formulas” on page 113.
