The small step response is given in Figure 12, and is the time
taken for the converter to settled to within 1 LSB.
ts
= 7
ms
(14-
bit resolution)
The large step response (steps >5% of FSR) applies when the
error voltage will exceed the linear range of the converter. Typi-
cally it will take three times longer to reach the first peak FSR.
In response to a velocity step [VELOUT/(d
θ
/dt)] the velocity
output will exhibit the same response characteristics as outlined
above.

SOURCES OF ERROR
ACCELERATION ERROR
A tracking converter employing a Type 2 servo loop does not
suffer any velocity lag, however, there is an additional error due
to acceleration. This additional error can be defined using the
acceleration constant K
a
of the converter.
K
a
=
input acceleration
position
The numerator and denominator’s units must be consistent.
K
a
does not define maximum input acceleration,
only the error due
to its acceleration. The maximum acceleration allowable before
the converter loses track is dependent on the positional accuracy
requirement of the system.
