Abstract

Ein Verfahren und eine Einrichtung zum Überwachen und/oder Steuern der Drehzahl eines Elektroantriebs mit einem über einen Frequenzumrichter (13) an ein Wechsel- oder Drehstromnetz (12) angeschlossenen Asynchronmotor (1), der mit einer Bremsvorrichtung (11) ausgerüstet ist, dient der Sicherheit beim Heben und Senken der Last. A method and device for monitoring and / or controlling the speed of an electric drive with a via a frequency converter (13) to an alternating or Three-phase network (12) connected asynchronous motor (1) with a Brake device (11) is equipped, serves for safety when lifting and lowering the burden.

Es wird vorgeschlagen, daß das maximale Drehmoment (16), das der Hubantrieb für das Anheben einer Last erzeugt, kleiner als das Haltemoment (17) der Bremsvorrichtung (11) eingestellt wird. It is proposed that the maximum torque (16) that the lifting drive generates for lifting a load is set to be smaller than the holding torque (17) of the braking device (11).
