Abstract:
1. A motor control device for controlling a motor for driving a mechanical load, based on a detection information signal input from a detector that is connected to the motor, the motor control device comprising: a command status determination unit for outputting, as a command status signal, a result of determining a status of a command signal, including information indicating presence or absence of a command speed in the command signal, the command signal output from a controller which outputs a control command to the motor; a follow-up control unit for receiving the detection information signal and the command signal to output, to the motor, a torque command signal for driving the motor and output a control status of the motor as a control status amount signal; a stopping-state response determination unit for receiving the command status signal and the control status amount signal to output, as a stopping-state response status signal, a result of determining a response status of the motor in a motor stopping state; an oscillation detection unit for receiving the control status amount signal to output, as an oscillation detection signal, a result of detecting oscillation of a control status amount that occurs in the follow-up control unit; an automatic adjustment unit for receiving the command status signal, the stopping-state response status signal, and the oscillation detection signal, the automatic adjustment unit comprising a plurality of adjustment modes for adjusting a control parameter of the follow-up control unit based on the received command status signal, the received stopping-state response status signal, and the received oscillation detection signal; and an adjustment start instruction input unit for receiving an adjustment start instruction from outside to output an adjustment start signal, wherein the automatic adjustment unit comprises:
