PURPOSE:To present a motor controller for enabling the gain or high precision to be regulated and enabling the-motor speed of quick responding speed to be realized. CONSTITUTION:A means 20 for generating the speed deviation signal of an analog according to difference between speed command signal and speed feedback signal, a means 30 for setting the proportional gain of the speed deviation signal, a means 22 for generating the output of the proportional gain as a digital value according to the set proportional gain, and the D/A converter 25 of a multiplying type for amplifying the speed deviation signal to be multiplied by the digital value, and the proportional gain can be regulated in a digital way via the setting means. Besides, according to the digital value of the speed deviation signal, by a CPU, arithmetic is performed on an integrating compensation value, and in addition to the speed deviation signal, PI compensating is performed. By such composition, the proportional gain and integrating gain can independently be regulated. |
