I have an ES165 robot with a NX100 controller that we purchased and reconfigured from a welder application to material handler. The issue I have encountered is the teach lock will not release.
When I switch the pendant from teach to play mode, the screen changes from teach to play mode selected but my I/O in the PLC does not switch. When I look at the robot CIO, 50053 and 50054 do not change state when the selector is switched. I have checked the different parameters and all seems to be in order.
Any suggestions please.
