Summary:With this set or reference value transmitter which is controlled by a set or reference value clock pulse generator or transmitter regulation of the running-up or acceleration of electric motors, such as asynchronous motors, can be kept under control also in the upper rotational speed ranges of the motor by adapting the displacement path-reference value characteristic curve to the displacement path-actual value characteristic curve. For this purpose the reference value transmitter comprises a correction member, by means of which the displacement path-regulation deviation is supervised in such a way that if the greatest displacement path-regulation deviation associated with the maximum power of the adjusting or positioning members is exceeded, the clock pulse frequency of the reference value clock pulse transmitter is reduced proportionally to the excess. The displacement path-reference values are supplied to the displacement path regulation circuit in correspondingly larger time intervals until the greatest displacement path-regulation deviation is fallen short of, whereupon the reference value transmitter continues to operate with the original clock pulse frequency.
