Improved Systems Precision and Shortened Cycle Time<br />
High Response<br />
A 4th-order notch filter reduces phase delay to suppress<br />
mechanical resonance and improve velocity response of<br />
equipment.<br />
Vibration-damping Control<br />
With feed-forward vibration suppression control, vibrations<br />
at the processing point and base of a machine can be<br />
suppressed through simple tuning procedures. Up to 4<br />
types of vibration control frequencies can be selected.<br />

Shorter Position Settling Time<br />
A new algorithm drastically shortens positioning settling<br />
time for equipment.<br />
Disturbance Suppression<br />
It is possible to control impacts from other axes in case<br />
of multiaxial constitution, by using the new disturbance<br />
observer with extended applicable frequency.<br />
