Motor control device and correction data generation method in same |
摘要 |
In-forward-rotation command information is obtained by sampling command signals during one or more rotations of a rotary shaft in a constant speed region while a motor is driven in a forward drive pattern including the constant speed region where the rotary shaft rotates in a forward direction at a constant speed. In-reverse-rotation command information is obtained by sampling the command signals during one or more rotations of the rotary shaft in a constant speed region while the motor is driven in a return drive pattern including the constant speed region where the rotary shaft rotates in a reverse direction at the constant speed. Correction data is generated using the in-forward-rotation command information and the in-reverse-rotation command information. |

1. A correction data generation method for generating correction data in a motor control device that generates a position detection signal relating to a rotational position of a rotary shaft of a motor based on a signal output from a sensor in accordance with a rotational angle of the rotary shaft of the motor which rotates in response to a command signal and that controls the motor by feeding back a corrected position signal obtained by correcting the position detection signal with the correction data, the method comprising:
obtaining in-forward-rotation command information by sampling the command signals during one or more rotations of the rotary shaft in a forward direction in a constant speed region while the motor is driven in a forward drive pattern including the constant speed region where the rotary shaft rotates in the forward direction at a constant speed; obtaining in-reverse-rotation command information by sampling the command signals during one or more rotations of the rotary shaft in a reverse direction in a constant speed region while the motor is driven in a return drive pattern including the constant speed region where the rotary shaft rotates in the reverse direction at the constant speed; and generating the correction data using the in-forward-rotation command information and the in-reverse-rotation command information. |
