  • Servo motor drive control device for calculating consumed electric energy and regenerated electric energy
    Patent number: 8040097
    Abstract: A mechanical system includes a plurality of amplifier groups each having a common power source unit connected to a higher-level power source and a plurality of power supply units for supplying power to servo motors from the common power source unit. A servo motor drive control device of the mechanical system includes a plurality of amplifier group electric power detection units each determining an electric energy of the corresponding one of the amplifier groups.

  • Servo motor controller
    Patent number: 7956568
    Abstract: A servo motor controller having: a frequency identification section that performs analysis based on a frequency response method and identifies the frequency of a disturbance exhibiting a specified phase lag; an input/output gain identification section that identifies the input/output gain at the frequency identified by the frequency identification section; and a magnification factor resetting section that resets an adjustment magnification factor by performing a specified operation on a ratio between the identified input/output gain and a specified target value of the input/output gain.
