4.3 Potentiometer Operation

The potentiometer slider is sprung such that when released it returns to it's central
position. In this central position the piezo inertia motor is stationary. As the slider is
moved away from the centre, the motor begins to move. Bidirectional control of the
motor is possible by moving the slider in both directions. The speed of the motor
increases as a function of slider deflection. The maximum speed is entered as a step
rate (steps (drive pulses) per second) in the 'Max Step Rate' parameter in the 'Pot/
Buttons' settings tab - see Section 6.3.
