Abstract

PURPOSE:To enhance a frequency responsiveness in a low current command range of a servo motor by performing proportional-plus-integral control in the low current command range of the motor and integral-plus-proportional control in a high current command range. CONSTITUTION:An integrator A, a proportional unit B and a limit function unit C are provided in a path of a current feedback signal. Here, when the unit C is set to '0', the input signal of the unit B is the current feedback signal and integral-plus-proportional control takes place. When an arbitrary value is set in the unit C, the input signal of the unit B becomes (speed deviation signal)-(current feedback signal), and when the speed deviation signal falls within a limit value, proportional-plus-integral control takes place and when to exceeds a limit value, integral-plus-proportional control takes place. When the set value of the unit C is infinitely increased, proportional-plus-integral control takes place.
