Abstract
A motor control device is equipped with a command receiving unit adapted to receive a movement command and a first control period of the movement command from a numerical controller, a command generating unit which, on the basis of the first control period and a second control period which is determined in advance, is adapted to generate a movement command of the second control period from the movement command of the first control period, and a motor control unit adapted to control a motor, in accordance with the movement command generated by the command generating unit.
Claims6
A control system comprising a motor control device and a numerical controller,
- the motor control device comprising:
- a command receiving unit adapted to receive a movement command and a first control period of the movement command from a numerical controller;
- a command generating unit which, on the basis of the first control period and a second control period which is determined in advance, is adapted to generate a movement command of the second control period from the movement command of the first control period;
- and
- a motor control unit adapted to control a motor, in accordance with the movement command generated by the command generating unit,
- wherein
- the numerical controller includes
- a period setting unit adapted to set the first control period;
- and
- a period receiving unit adapted to receive the second control period from the motor control device,
- the period setting unit sets as the first control period a period that is longer than the second control period.
A motor control method for controlling a motor, comprising:
- a command receiving step of a motor control device receiving a movement command and a first control period of the movement command from a numerical controller;
- a command generating step of the motor control device generating, on the basis of the first control period and a second control period which is determined in advance, a movement command of the second control period from the movement command of the first control period;
- a motor controlling step of the motor control device controlling the motor, in accordance with the movement command generated by the command generating step;
- a period setting step of setting, by the numerical controller, the first control period;
- a period receiving step of receiving, by the numerical controller, the second control period from the motor control device,
- wherein in the period setting step, there is set as the first control period a period that is longer than the second control period.
