Abstract
A method for driving a component placement device, the component placement device having a machine frame, component pickup units and a subframe, the first and second component pickup units configured to be movable in a direction of travel, the method comprising: moving at least one of the component pickup unit in the direction of movement relative to the subframe, the component pickup units and the subframe configured for a reactive force to be exerted on the subframe by the moving of the at least one of the component pickup units; determining a counterforce to be exerted against the subframe substantially opposite a direction of the reactive force, the counterforce determined by an auxiliary control unit, wherein the counterforce at least partially counteracts the reactive force; and applying the counterforce to the subframe substantially in the opposite direction of the reactive force by at least one drive unit.
