Abstract
In a method of obtaining an error signal (15) in a positioning device (1), with which a tool (4) is positioned relative to target object (3), the tool's (4) acceleration in the direction of at least one of the tool's motion components is recorded with at least one sensor (10), and the target object's (3) acceleration in the direction of at least one of the target object's motion components, in which the tool's (4) acceleration is also recorded, is also recorded with at least one sensor (12). A differential signal is formed from the accelerations of the tool (4) and the target object (3).
