Abstract: A robot teaching dvice allowing a user to operate an enable switch provided on the robot teaching device in a similar manner regardless of the user's dominant hand. A hand-held robot teaching device includes an enable switch built-in includes a main body including a holding portion that is configured to be held by one hand, and an enable switch operating section that is provided on the holding portion and is configured to be operated by a reference switching motion of a hand holding the holding portion in a reference position. The enable switch operating section includes a switching motion specifying mechanism that makes the reference switching motion in the reference position easier than another motion.

Abstract: A motor drive device includes: a converter which converts AC power of an AC power source side to DC power and outputs the same to a DC link; a DC link capacitor;an inverter in which each switching element is controlled based on a switching drive signal supplied, thereby performing power conversion between DC power of the DC link and AC power of a motor side; a DC/DC converter which converts DC power of the DC link to DC power for a control power source; a servo motor control circuit which outputs the switching drive signal; a torque cut-off circuit which cuts off source of each switching drive signal to each switching element, thereby stopping a motor when not receiving a safety signal; and a safety monitor circuit which stops transmission of the safety signal during an abnormality of the torque cut-off circuit.

Abstract: 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.
