Abstract
A holding head includes an axially driveable shaft having a nozzle at one end of the shaft for holding a component, a motor for driving the shaft in an axial direction in response to power supplied to the motor, and a detecting device for detecting movement of the shall in the axial direction. A method of operating the component holding head comprises using the detecting device to detect movement of the shaft in the axial direction resulting from the shaft being driven by the motor, and controlling power supplied to the motor in response to the movement of the shaft as detected by the detecting device such that the distance that the shaft is driven by the motor in the axial direction is controlled.
