Abstract
An endoscopic system (10) comprises an actuator (12) at a distal end (14) of the system (10), a manually operable actuating unit (18) at a proximal end (16) of the system (10), for actuating the actuator (12) and choosing an actuator force (F) by means of which the actuator (12) is intended to act on an object (20), the actuating unit (18) being displaceable between a start position and an end position, an actuator motor (24) designed to drive the actuator (12), and a control unit (30) designed to drive the actuator motor (24) initially on the basis of a position sensor (38) without exceeding a limit value (FTH) and then on the basis of a force sensor (40). Further, a method for driving an actuator (12) of an endoscopic system (10) is disclosed.

-9. (canceled)
A method to drive an actuator of an endoscopic system, comprising:
- actuating an actuator motor, that is operatively connected to the actuator,
- depending on a current position of an actuating unit of the endoscopic system when the actuating unit is actuated between a start position and an end position and when an actuator force exerted by the actuator does not exceed a limit value,
- ceasing actuation of the actuator motor when the actuating unit is actuated between the start position and the end position and when an actuator force exerted by the actuator reaches or exceeds the limit value, and
- driving the actuator motor beyond the limit value (FTH), depending on an operating force exerted on the actuating unit, when the actuating unit is actuated in the end position.
