Abstract
The method for monitoring the end positions of a controlling element having a servomotor (1) comprises the recognition of the end position, for instance by interruption of the flow of current to the servomotor by limit switches (4, 5), and the subsequent action of a control pulse of opposite direction on the servomotor in order to brake the servomotor.
