SOURCES OF ERROR
Acceleration
A tracking converter employing a Type II servo loop does not
suffer any velocity lag. There is, however, an error associated
with acceleration. This error can be quantified using the
acceleration constant (Ka) of the converter.

Figure 15 shows tracking error versus acceleration for the
AD2S1200.
The numerator and denominator’s units must be consistent. The
maximum acceleration of the AD2S1200 has been defined as
the acceleration that creates an output position error of 5°
(when LOT is indicated). The maximum acceleration can be
calculated as
