    摘要: A servo controller capable of preventing downward displacement of a gravitating axis of a machine when an excitation of a servomotor for driving the gravitating axis is discontinued. When a shutdown command is issued, a command for shifting a position of the gravitating axis by an offset amount in a direction opposing the gravitation is issued to a servo system. Also, a command for operating a mechanical brake to apply a braking force on the gravitating axis is issued. After a predetermined time period, the excitation of the servomotor is discontinued. The position of the gravitating axis is shifted upward by the offset amount within a time-lag between an issuance of the mechanical brake operating command and actual application of the braking force by the mechanical brake, and the braking force is applied to the gravitating axis at the shifted position. When the excitation of the servomotor is discontinued, the downward displacement of the position of the gravitating axis due to a backlash of the mechanical brake is compensated by the upward shifting of the gravitating axis, thereby movable elements connected to the gravitating axis is prevented from collision or interference with peripheral objects.

    摘要: An automatic machine has a plurality of axes driven by servo motors. The controller for controlling this automatic machine confirms that a compulsory power disconnection mode is engaged, releases the brakes and starts power supply to servo amplifiers. At a prescribed time after power supply to said servo amplifiers has started, the power supply to the servo amplifiers is halted compulsorily. Alternatively, the power supply to the servo amplifiers is halted compulsorily at a prescribed time after power supply to the servo amplifiers has started and after initial movement commands have been input to the servo controllers.

    摘要: A system is disclosed for conserving power in a robotic arm device. The robotic arm device is responsive to a motion command and controlled by a servo loop having a motor, a motor driver, and a motor encoder. The system positions the robotic arm to a stow position when the time since a last motion command exceeds a predetermined power shut down time. When the robotic arm has reached the stow position, power is removed from the motor and the motor drivers by opening the servo loop. Thus, power is conserved while the robotic arm rests in its stow position. When a new command is received, the servo loop is closed and power is applied to position the robotic arm to its desired position.
