ABSTRACT:
A servo device which simultaneously controls plural servo systems, using a digital signal processor (DSP). The servo device includes plural servo systems, plural control subjects, and plural sensors which determine control quantities of the respective control subjects. The servo device also includes a calculation processing device which finds operating amounts of the respective control subjects from the control quantities which have been detected. The calculation processing device measures the gain of each servo system, and during the gain measurement of a given servo system, drops the control band of other servo systems, or sets the other servo systems to OFF or HOLD.
