ABB EPS

EPS

In robot system there's a connection to external safety devices, often a PLC in combination with door locks, light barriers or safety scanners that ensures the robot can be stopped in a safe way.

With the  Electronic Position Switch feature, EPS, the IRC5 controller can monitor where the robot is and communicate this information to the outside world using a set of I/O signals. You define ranges for the robot joints, and the EPS monitors the robot to see if it is inside or outside the ranges.

The EPS cannot stop the robot; it is a passive safety system that always needs to be connected to safety relays or a safety PLC.
