5. Introduction 9 10 Introduction Slow action of the Picomotor high static friction causes the screw to rotate while fast action low dynamic friction causes no rotation By sending pulses with fast rise times and slow fall times the piezo will rotate the screw counter clockwise Similarly sending pulses with slow rise times and fast fall times rotates the screw clockwise The knob on the end of the drive screw provides inertial mass required for operation Removal of the knob will prevent the Picomotor from functioning properly and void the warranty The single axis and multi axis drivers generate the 120 V pulses required to drive the piezo in the Picomotor The drive circuit consists of a voltage controlled oscillator VCO some logic elements and a power field effect transistor circuit FET which produces the 120 V pulses Step Size and Repeatability The Picomotor is not a stepper motor Because it is a friction mechanism it does not produce identical steps for each input pulse Although the step size can vary slightly from pulse to pulse it will always be less than 30 nm for the standard Picomotor for the tiny Picomotor step size will be less than 100 nm In addition when starting the motor from a standstill or changing its direction the Model 8701 and Model 8801 drivers have to bootstrap the pulses up to a stable amplitude This can result in a significant variance in step size for up to the first 10 puls
