Abstract

PURPOSE:To effectively prevent an insufficient torque or an overexcitation in a motor by individually correcting output voltage in response to the operation mode of a load, such as a motor. CONSTITUTION:A set value current signal 26 from a predetermined value setter 12 is input through a switch 17 as an acceleration time voltage correction signal 28 to a PWM controller 8 at the time of acceleration, and the controller 8 optimally controls the torque of a motor 5 through an inverter 4 on the basis of it. A constant time voltage correction signal 29 is output through a switch 18 to an adder 9 at the time of constant speed operation, the adder 9 outputs a voltage signal 24 to the controller 18 to optimally control the torque of the motor 5. Operation mode control signals 31, 32 are not output at the time of deceleration, the switches 17, 18 remain open and the controller 8 is not corrected.
