PURPOSE:To dispense with any trouble for adjustment of an R/D (dosage per angle) control circuit as well as to aim at improvement in control accuracy, by setting all operational parts of the said control circuit down to a digital control system by means of a microcomputer. CONSTITUTION:To perform operation of R/D (dosage per angle), a microcomputer 19 inputs each signal of a does monitor and a tachometer generator 4 from an analog-to-digital converter 17 and simultaneously the setting value of this R/D from a digital switch 18, respectively. At this time, since there are plural analog signals, they are serially inputted by channel transfer control with a multiplexer 16 and a simple hole circuit 17. Operation is carried out on the basis of the inputted data, outputting the result to a D/A converter 21, and repeative operating frequency of a generator is controlled. With this constitution, trouble for adjustment of an R/D control circuit is omitted, while control accuracy is raisable.
