Note the critical damping in figure 24.

There is no appreciable overshoot nor

undershoot. The step response for this

scanner/servo system is about 1.25msec.

The scarmer is considered settled when the

position signal has settled to within about

ofthe length ofthe step. The exact step

response time will vary from system to

system depending on load dynamics and

scanner size.
