Abstract
A robot control device that controls a robot including a motor, the robot control device comprising: a power converter that is connected to the motor by a power line and converts supplied power to power to be supplied to the motor; a brake that brakes the motor by short-circuiting the power lines, and an inductance element that is provided on the power line and positioned closer to the power converter side than a connection point between the brake and the power line.
Claims19
A robot control device that controls a robot including a motor, the robot control device comprising:
- a power converter that is connected to the motor by a power line and converts supplied power to power to be supplied to the motor;
- a brake that is connected to the power line by a brake line, the brake being configured to brake the motor by short-circuiting the power line, a connection point between the brake line and the power line being provided between the power converter and the motor;
- a current detector being provided on the power line between the power converter and the connection point;
- and
- an inductance element that is provided on the power line between the current detector and the connection point and positioned closer to the power converter than the connection point between the brake line and the power line.
A robot that is controlled by a robot control device, the robot comprising:
- a power converter that is connected to the motor by a power line and converts supplied power to power to be supplied to the motor;
- a brake that is connected to the power line by a brake line, the brake being configured to brake the motor by short-circuiting the power line, a connection point between the brake line and the power line being provided between the power converter and the motor;
- a current detector being provided on the power line between the power converter and the connection point;
- and
- an inductance element that is provided on the power line between the current detector and the connection point and positioned closer to the power converter than the connection point between the brake line and the power line.
A robot system comprising:
- a robot including a motor;
- and
- a robot control device that controls the robot, wherein
- the robot control device includes a power converter that is connected to the motor by a power line and converts supplied power to power to be supplied to the motor, a brake that is connected to the power line by a brake line, the brake being configured to brake the motor by short-circuiting the power line, a current detector provided on the power line between the power converter and the connection point, and an inductance element that is provided on the power line between the current detector and the connection point and positioned closer to the power converter than a connection point between the brake line and the power line,
- wherein the connection point between the brake and the power line is provided between the power converter and the motor.
