    摘要: The servomotor control device includes: an inverter circuit that drives a servomotor; a PWM circuit that outputs a PWM signal to the inverter circuit; a cutoff circuit that receives a safety signal and the PWM signal, outputs the PWM signal to the inverter circuit when the safely signal is turned on, and does not output the PWM signal when the safely signal is turned off; and a servomotor control circuit that outputs the safety signal to the cutoff circuit and receives a monitor signal output from the cutoff circuit, the servomotor control circuit turning off, within one cycle time of the PWM signal, the safety signal input to the cutoff circuit where the PWM signal is turned off during servomotor drive and detecting an abnormality when an off state is not detected using the monitor signal.

    摘要: A robot includes a motor that includes a brake and moves an arm on a drive axis, and a rotational position detector that detects movement of the arm. When a state occurs in which the robot is preferably emergency-stopped, a control device performs an emergency stop control in which the brake is operated and power supply to the motor is interrupted. When the movement of the arm is detected based on an output of the rotational position detector during the emergency stop control, the control device supplies power to the motor to prevent the movement of the arm.

    摘要: A mobile collaborative robot includes a force sensor which is provided on a robot support on a carriage, a robot information acquisition unit which acquires robot information including posture information of the robot main body and load information of a load acting on the robot main body, a force calculation unit which calculates the external force acting on the robot support based on the robot information, and a judgment unit which judges that the mobile collaborative robot has come into contact with a human when a difference between the external force detected by the force sensor and the external force calculated by the force calculation unit is above a predetermined value α or when a difference between the amount of change in the detected external force and the amount of change in the calculated external force is above a predetermined value α1.

    摘要: A circuit breaking system includes an output device for outputting an output signal; a control device controlled by the output signal; a power input terminal provided in the output device, for supplying power to the control device; a power supply to the output device, which has a ground terminal; a break circuit disposed between a power output terminal and the power input terminal; a switching circuit disposed between the break circuit and the power output terminal; and a short circuit disposed between a ground and a node which connects the power input terminal and the break circuit. The break circuit and the short circuit are operated so as to not be closed at the same time. When the switching circuit is closed, the break circuit is closed while the short circuit is open. When the switching circuit is open, the break circuit is open while the short circuit is closed.
