Analysis procedure operation of an electromechanical actuator for operating a motorized screen and actuator for application

摘要

Method for operating an actuator (1) for driving a movable member (52) comprising a motor (10) of asynchronous or brushless type or comprising an associated differential brake (20) engine, and comprising a reducing (30) partially irreversible, the method comprising a step of establishing a measure of an operating parameter (ΔEV) actuator and a step of using this measurement to determine if the actuator drives the movable member or actuator leads the movable element, wherein the method comprises a step of applying a first logic for determining a limit switch or an obstacle, or a step of applying a second determination logic of a limit switch or an obstacle, depending on whether the actuator drives the movable element or the actuator leads the movable element.
