need help for RH controller problem("e-stop on UOP1" problem)

[terminator]

hi guys.

I have a s420F robot with rh controller.I try to fix all the fault and want to move the robot.but we don't fix one of the fault.controller gives "4002 emergency stop 200" error.when we look at signal status(f8), "E-stop UOP1" is always true.and we couldn't change it to false.

so, I need your help to overcome this issue.

I attached some pictures.may be these pictures help you a little


and I need programming,operating manuals for this robot.I appreciate if someone sends me . mail : term1903@yahoo.com


thanks for your answers

you have a estop pushed in somewhere!!!

4002 SVAL EMERGENCY STOP xxx
An EMERGENCY STOP button was pressed. The "xxx" indicates the source of the EMERGENCY STOP:
100: E-stop on operator panel
200: E-stop on UOP 1
400: E-stop on Fence
800: E-stop on Teach pendant
Release the EMERGENCY STOP button. Then press the RESET button on the operator panel or press the RESET key on the teach
pendant.

I am sure you already checked the emergency by now, if it did not work probably you should check your emergency push button contacts (The hardware)

I had a similar problem in the past and it turned out to be a switch problem

hi
thanks for  answers

I checked both of teach pendant and panel emg push buttons. they are working properly.

fault says "e-stop on UOP1".
as far as I know , UOP signals comes from an external source.
at present condition , there is no external connection to the robot.

fanuc_insider told me that I could check the $udin_enbl variable and changed it to false.I checked it and it is false

additional information : there is no power at I/O module.when I checked a schematic about controller , I understood that it is powered when all faults were cleared.is it true?



it seems to me that I must bridge some connection to disable UOP estop, but which connection?

It's likely that you will need to find the location of the UOP/workcell inputs (e-stop, fense, servo disconnect, etc) and jumper out the ones for the e-stop. I'm not sure on these older controllers since I've never worked on one of those, but I assume they are similar since the safety systems are hard-wired.

Sounds like you *really* need an electrical maintenance manual. Maybe someone has one for the older style controller being used...

same problem with my RH after some time of being unused. all batteries died, so we've replaced them and tried to launch the robot after that. the controller displays 4002 Emergency stop 200. uploading a "new" software did not help, there is nothing connected, no UOP, $udin_enbl variable is set false, nothing has been changed since last proper launch of the robot. I've also briefly checked all wire connections and bridges I could find inside the controller...

terminator, have you solved the problem?

no. I didn't find any solution yet.

well, my fanuc is all ok again... our boss took away a wire that bridged UOP1 E-stop contacts in the I/O module and noone knew he did it  we've refitted a new one and everything is running fine :)

could you tell me which contacts are in the I/O module.may be we  have same or smilar I/O configuration.

Hi everybody.
Bidzej's fanuc is all right now. End this is the solving of His (my too)  problem: :)
We connected  1st and 2nd input on I module ( ID16C - but i.dont know which module, couse they look all the same- you must try with all, until you get the right).
Then we put in one of this input: 24 DC voltage. Of course You cant forget about COM input (4 in I module) to connect them together.
