Abstract: A motor drive device includes: a position command generator which generates a position command; a damping filter unit which includes one or more stages of damping filters which reduce vibration of a device including a load and a motor, applies, to a position command, a damping filter determined based on a model parameter corresponding to a model of the device, and outputs a filtered position command to which the damping filter has been applied; a servo controller which gives a torque command to the motor based on the filtered position command; a low-pass filter unit; a parameter estimation unit which estimates the model parameter from the rotational speed and the torque command of the motor which have passed through the low-pass filter unit; and a vibration determination unit which determines presence or absence of vibration in the model.

Abstract: In a customization method of a motor control device, a customization module for executing a modifying operation of a specific function in a customizing element is formed. A customization module group is configured by a set of customization modules. The user can form a user module for executing an operation related to the specific function in the customizing element. A buffer memory accessible from both the customization module and the user module is provided. The customization module is configured to execute the operation related to the specific function based on data received from the user module via the buffer memory.
