Newport ESP300 Series User Manual

Both error plots from Figure 5.3a and Figure 5.3b have a similar
maximum Error. But, if the user compares the maximum Error for
small distances, the system in
Figure 5.3b shows significantly larger
values.

Figure 5.3b: Low Accuracy for Small Motions
For applications requiring high accuracy for small motions, the
system in Figure 5.3a is definitely preferred.
"Local Error" is a relative term that depends on the application;
usually no Local Error value is given with the system specifications.
The user should study the error plot supplied with the motion device
and determine the approximate maximum Local Error for the specific
application.
