Abstract

PURPOSE:To perform perfect speed control of uniform drive in a whole system by making the value of reference pulse trains counted by predetermined sampling time as common speed reference. CONSTITUTION:The pulse train speed reference RP from a pulse oscillator 10 is supplied to a common digital speed setting circuit 1 and a PLL control circuit 11 of each motor. The speed setting circuit 1 outputs digital speed reference DD. The digital speed reference DD is inputted to each speed control arithmetic section 2 by the computer of the control section of each motor. The PLL control circuit 11 outputs an analog signal Y which is proportional to the phase difference between the pulse train speed reference RP and a feed back pulse FP. The pulse phase difference signal Y is added to the analog current reference in a current control section 3.
