Abstract

An arrangement and method for the electronic monitoring of an adjustment drive wherein two criteria must be met before a jamming safety responds. The one criterium takes into account the curve for the rotational speed of the actual and a preceding operation of the adjustment drive while a first and/or second derivative of measured value for the adjustment drive are incorporated into the second criterium.
