Abstract
A mover assembly (16) that moves or positions an object (12) includes a mover output (226), an actuator (230), and a control system (18). The mover output (226) is connected to the object (12), and the actuator (230) causes the mover output (226) to move. The control system (18) selectively directs a drive signal to the actuator (230) in a first mode and in a second mode. In the first mode, a peak voltage and a baseline voltage are sequentially directed to the actuator (230). In the second mode an intermediate voltage is directed to the actuator (230), the intermediate voltage being intermediate the peak voltage and the baseline voltage.
