Digital servo-control system.

摘要

A digital servo-control system used for driving a machine with a plurality of drive shafts having a digital type multi-axis position control unit (31), provided in common to all of the drive shafts, for computing a torque command value (Ic1 to Ic4; Tc1 to Tc4) for each drive shaft on the basis of a position detection value (Xfi) detected by a position detector (40 to 43) provided for each drive shaft and a position command value (Xci) for each drive shaft, and torque control units (32 to 35; 70 to 73), respectively provided in correspondence to a plurality of motors (39; 89) adapted to drive the respective drive shafts, for controlling output torque of a corresponding motor in accordance with the computed torque command value.
