Arrangement for influencing the transitions in a desired-value transmitter in rotation-speed-regulated systems, especially in lifts

摘要

An arrangement is described by means of which the desired value transmission for the speed response is influenced by means of an optically coupled desired value transmitter. In this case, the input voltage for an integrator is influenced by means of an electronic amplifier in such a manner that the time response of the integrator output voltage corresponds to the desired time-dependent desired-value response. The gain level of the amplifier is influenced by the input voltage of the optocoupler.
