ABSTRACT:
A servosystem in which means are provided so as to prevent impartation of an excessively high acceleration to its movable part even when an abnormal input signal is applied to the servosystem. The apparatus comprises an acceleration limiter circuit which modifies such an abnormal input signal so that an acceleration higher than a predetermined level may not be imparted to the movable part.
