ABSTRACT:
Where T.sub.1 is a period of a dynamic operation range of a phase comparative waveform of a motor servo apparatus, and a period T.sub.0 of a reference phase signal is measured, the reference phase signal is delayed by T.sub.3 =T.sub.0 -T.sub.1 /2 to obtain a gate signal. The dynamic operation range is started by the gate signal. Thus, the operational center of the phase system is brought in line with the dynamic operation range. The operation is made symmetrical in the dynamic operation range to achieve a rapid servo lock and a stable phase control over the motor servo apparatus, even at the start of the motor or when an external perturbation occurs.
