Control device for robot

Abstract

Abstract PURPOSE: To surely stop a robot in emergency when a connector is unexpectedly disconnected by connecting a connector disconnection detecting means on a control device body side to pins at both ends of the connector. CONSTITUTION: When a connector disconnection detecting means 10 having input terminals on the pins A, B of a connector 5 on a control device body 7 side detects the unexpected disconnection between the connector 5 and a connector 3 on an auxiliary device side, the logical product of the detecting means 10 becomes inactive. The pin C of the connector 5, i.e., the input M of an emergency stop input interface 13, is made open, and an emergency stop signal M' is outputted from the interface 13 to the logic circuit 19 of the control device body 7. A robot is stopped in emergency based on the signal M'. COPYRIGHT: (C)1989,JPO
