Abstract
A circuit for supplying/interrupting power to robots in a robot control system which controls two robots by use of one controller. This circuit for supplying/interrupting power to robots includes a common power interrupting circuit, which simultaneously interrupts power supplies to two robots, and power interrupting circuits for individual robots, which individually interrupt power supplies to individual robots. When a common cutoff switch circuit in the common power interrupting circuit is operated on the basis of an emergency stop signal or an alarm signal, two relays are deenergized at the same time, thereby simultaneously interrupting power supply to two robots. When one of the cutoff switch circuits in the power interrupting circuit for each robot is operated by an emergency stop signal or an alarm signal, only one corresponding relay is deenergized, thereby interrupting power supply to one appropriate robot.
