Abstract
A vibration mode determining apparatus that determines vibration mode of a machine structure of a machine including motors and that includes a vibration command generating unit that generates a vibration command for the motor; a control unit that generates a current command for the motor according to the vibration command and outputs a conversion value for a motor excitation force to a vibration mode calculating unit; a motor drive unit that receives the motor current command and drives the motor; a vibration sensor that detects vibration of the machine structure; a measurement-point information input unit that sets information about the attachment point of the vibration sensor; a vibration mode calculating unit that calculates the vibration mode using the conversion value for the motor excitation force and the output of the vibration sensor; and a vibration mode output unit that outputs the vibration mode.
