Robots that are hung upside down are mastered differently. I will look for more info in the manual. There is a master position for zero on your 7th axis. Also just because the master counts are different doesn't mean the mastering is off

Delete your program and recreate it. You can't add line tracking to a program that was not created with line tracking in it.

This is a setup issue. The backlash was inadequate. Make sure the backlash is set at the highest point on the gear rack. Most rail manufacturers have a fixture where an indicator can be mounted to measure this.

I would say the SRAM is bad

What happened when you tried INIT start?

The only places you can "get a backup" are from the original owner or the original programmer integrator.
You will have to get it "fixed" and/or reload the software. For now you can try an INIT Start.
Turn off the controller, press and hold the F1 and F5 buttons on the teach pendant while turning on the controller. Hold the F1 and F5 buttons down until the robot "boots up". Select "INIT start" from the menu.
****WARNING****
An INIT Start will wipe out everything that was programmed in this robot. It will be in an "as delivered" state from Fanuc.
All programs, I/O settings, and configuration will be lost and unretrievable.

OK turn off the controller, press and hold the PREV and NEXT buttons on the teach pendant while turning on the controller. Hold the PREV and NEXT buttons down until the robot "boots up". Select "controlled start" from the menu.
If it boots up, you will need to "cold start" it by pressing function and then "cold start".

Try a controlled start.
Is this a "down" production robot or is it something new you are trying to get running

Did you disconnect the teach pendant with the power on? Only disconnect it with the power off!

Thanks DaveP and prasolet. The CIO Micro is not an option because I need more than 8 outputs.
I ordered th aoption from Fanuc and I plan to set it up next week if I have time. I'll post the results.

It's fixed. I got an answer from Cognex. The robot needs the option, Ethernet/IP Scanner. You can then configure digital Inputs and outputs and group inputs.

Does anyone have experience interfacing directly with a Cognex camera or barcode reader?
I have an R30iB+ Mate. I am looking into what type of data I may be able to read, store, and send to a PLC.
Basically I need to read the code, determine the location of the code, calculate an offset to print another code next to the original, and then send the code to a PLC.
We are replacing an Adept with an LR Mate and the Adept is currently doing all of these operations.

In the file menu press F5 and select device, then select UT1

Whats the name of the variable?

Siemens S7300 series.
Scan times to the robots is 2ms.
What do you mean speed overide is active?
I don't think it is a bad cable because multiple robots are on the same switch and only one will fail.
The alarm is very intermittent, occuring once every couple of months.

We are getting a PRIO-379 PRIO Chnl 2 Slot 1 idle intermittently on one of our lines. When this happens the effected robots slow down to 10%.
Fanuc says the PLC is the cause and our PLC guy says it's the robots. Not all robots are effected when this happens and that leads me to believe it isn't the PLC. Has anyone else had this alarm and if so what did you do to remedy it?

LR Mates have harmonic drives which are fragile.
A seemingly insignificant collision can damage the drive causing the problems you are experiencing.
Jog each axis through it's full range and look for bouncing. If it does you will need to tear it down for inspection.

Quote from HawkME

I think he is wanting to prevent the robot from hitting itself with the EOAT, which I don't think is directly possible, because the DCS zone check will check the moving target versus a fixed zone, but doesn't allow checking target versus target (target being the robot model or a user model). If you know of a way to check target vs. target I would be very interested.

As an alternative I suggest using a combination of Joint limits and Orientation check for tool to robot collision prevention.

To prevent the new tool from hitting the fence you will want to use the normal DCS position check with a user model.

HawkMe is right. The tool can still hit the robot

You can teach a box around the tooling to prevent this. Is the tool fram taught?

I tried changing the software version from the original backdate file, and that didn't work.
