controls the VCO, to dynamically correct possible changes, due to changes
in the load, of the handpiece resonating frequency.
Piezo handpiece is connected to J1 card connector and is driven by a
sinusoidal voltage of variable frequency and amplitude. The frequency of
the voltage supplied to the handpiece is automatically adjusted by the control
circuit in order to match the resonating frequency of the acoustic vibrator.
Frequency ranges from 37.5 to 43 KHz.
The amplitude of the voltage supplied to the handpiece determines the
stroke at the edge of the ultrasonic tip. Amplitude is changed by the control
circuit according to the U/S POWER value set by the operator.
This amplitude ranges from 100 to 500 V (peak).
