Abstract
A robot control device includes an operation mode change-over switch for switching between a first operation mode for prohibiting an operator from approaching a predetermined area around a robot when power is supplied to a drive motor for driving the robot and a second operation mode for allowing the operator to approach the predetermined area around the robot even when power is supplied to the drive motor, and an electromagnetic contactor for switching the connection and disconnection of the power supply line to the drive motor. The robot can be stopped in case of emergency by using the electromagnetic contactor to disconnect the power supply line. The apparatus further includes an emergency stop control unit. The emergency stop control unit issues a disconnection command to the electromagnetic contactor, when the switching between the first and second operation modes is sensed, and automatically confirms whether or not the power supply line is disconnected.
