摘要： A control apparatus of a press machine in which a motor performance torque is fluctuated in accordance with a rotational angle of the rotating body in the case of rotating the motor at a fixed instruction speed. The control apparatus includes an angle detecting apparatus detecting a rotational angle of the rotating body, a torque determining apparatus determining a necessary motor torque in correspondence to a characteristic of the press machine on the basis of a value of the rotational angle input from the angle detecting apparatus, and a speed adjusting apparatus increasing the rotational instruction speed of the motor to a value more than the fixed instruction speed, at the rotational angle of the rotating body in which the necessary motor torque becomes smaller than a predetermined motor torque reference value.
