Abstract
PURPOSE: To stably control the number of revolutions by preventing the control unstability area from occurring when the speed signal and phase signal of a body of rotation aredetected and the number of revolutions is controlled with the signal converted into the analog signal using the DA converter.
CONSTITUTION: The capstan servo circuit consists of the speed control circuit 100, phase control circuit 102, and clock signal generator circuit 104. The speed control circuit 100 contains preset type 4-bit counter circuits 106 to 112 the counters are provided with the respective load input LO and clock input CK terminals from the load pulse generator circuit 114. It also has the first and second 4-bit latch circuits 136 and 138. These latch circuits receive the 8-bit output from the counter circuit. The 8-bit latch output is applied to the DA converter 140 and the output of the DA converter is applied to the capstan motor through the motor driving amplifier.
