How does one clear this error from an RJ2 system? I've done it before, but it's been quite some time and I can't remember what I did.
The robot is a S420iW that is currently not equipped with anything. No too, safety measures (it's all been jumped), or UOP.
your must turn on the Enable on the UOP
Yeah, that's the thing though is that there is no UOP.
Menu - I/O - Type, does not have UOP listed? 
My apologies! It most certainly does have UOP listed. What I meant is that we are not using UOP for anything at the moement, and are only trying to jog the robot.
There is a system variable.
$OPWORK.$uop_disable
When disabled, the controller ignores UI[1] - UI[18] and this should allow you to jog.
this just helped me out - thanks!!
Hi, I have S-420if with Rj2 controller , I take same alarm , I do not use any input. how can I disable the OUP ?
Menu, 0, 6, F1 type, Config. Scroll down to item 7 enable UI signals and toggle it to false.
