Abstract:
1. A method for driving a component placement device, the component placement device having a machine frame, first and second component pickup units and a subframe, the first and second component pickup units configured to be movable in at least a direction of movement, the method comprising: moving at least one of the first and second component pickup unit in the direction of movement relative to the subframe, the first and second 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 first and second component pickup unit; 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.
