Claim 1:
2. The method according to claim 1, wherein each sawtooth-waveform drive voltage signal cycle (C) in the Step A comprises the following phases:
a. a first phase (1) representing a stick (move) phase in which the drive voltage (V) increases from a base voltage (Vb) to the peak voltage, (Vp);
b. a second phase (2) representing a pause after the first phase (1) in which the drive voltage (V) is maintained at the peak voltage (Vp);
c. a third phase (3) representing a slip phase in which the drive voltage (V) decreases from the peak voltage (Vp) to the base voltage (Vb); and
d. a fourth phase (4) representing a pause after the third phase (3) in which the drive voltage (V) is maintained at the base voltage (Vb).
