<p>PURPOSE:To decrease the number of circuit constituting elements and at the same time to absorb the variance of DC characteristics of a motor to control the offset of a phase deviation, by using an automatic position control information processing part and an automatic frequency control information direct connection part. CONSTITUTION:An automatic phase control APC signal and an automatic frequency control AFC signal are supplied to an input part 1 and an input part 2 respectively. Then the APC signal is supplied to a multiplier 43 and an adder 44 of an APC information processing part 50. The adder 44 receives its own output data via a unit delay device 45 to add it to the APC signal. Thus the output of the adder 44 is equal to an integration output and supplied to an adder 47 of an AFC information direct correction part 51 via an adder 46. The adder 47 adds together the input received from the multiplier 43, the AFC signal received from the part 42 and the input received from the multiplier 46 and outputs them to a multiplier 48. Thus the DC direct connection is secured for the AFC signal and at the same time an integration means is provided to the part 50. Then it is possible to decrease the number of circuit component elements and to absorb the variance of DC characteristics of a motor as well as the offset of the phase control information.</p> |
