摘要：
A control device for phase-locking a rotating or traveling member to a reference signal within a short time at its starting stage, in which a phasic error signal produced as a result of comparison of the phases of the reference signal and a signal representative of the phasic position of the member is fed to the driver of the member through a gate which is non-conductive unless the speed of motion of the member reaches a predetermined value.
