An elevator system in which the movement of the elevator car is responsive to a comparator which provides an error signal responsive to the difference between the magnitude of a speed pattern signal provided by a speed pattern generator, and a signal responsive to actual car speed. An adjustable impedance device controls the affect of the speed pattern signal on the comparator, with the impedance of the adjustable impedance device being responsive to at least one predetermined parameter of the speed pattern signal. |
