Most likely an issue with disk 1, 2 or 3 where parts of the MC file are missing and it's going to disk 4 to finish loading the file. Try recopying the disks.

For a PNS start, you need to be in Remote and pulse ProdStart UI[18]. Start UI[6] is used to resume a paused program since Config line 8 is set to True.

Are you providing the e-stop board with an external source of 24V? If not, check on your e-stop board for a jumper between EXT24V and INT24V, and one between EXT0V and INT0V.
As mbull says, check for 24V between TBOP6-9 (EXT24V)& TBOP6-12 (EXT0V).
Make sure to check the fuses with a meter. Seen twice in the last year where a MP-style Daito fuse was fuse was open but the flag did not appear in the window.

What's happening is that, randomly, one of the welds comes out much smaller than it should be, as if the amps drop suddenly, or the speed increases drastically.
Can you give more detail? Does the weld stay small until the ArcL\Off and then what happens? Do the smaller welds still give good penetration?
For the analog, is a DSQC209 or a Combi board (DSQC224/315)? Are the analog signals in a shielded cable and away from high current cables such as weld, motor, power?
Have you tried creating new SEAM data and using that? Is it possible it stops weaving to cause the weld widths to be smaller?
I would pull the weld cables and thoroughly inspect, especially if there's a positioner/turntable involved.

TAST has a lot of conditions to get it to work properly and consistently. My suggestion would be to get an ArcTool manual to help you decide if your process is a good candidate and describes all the necessary steps to setup a good TAST schedule and troubleshooting TAST issues. What version of ArcTool are you using?

Milco has almost always given me information if I can provide accurate tag information and Warren W. was always willing to help. If I remember right, some of their old stuff was lost to computer issues years ago.
See if the older manual attached is any help.

In addition to Hermann's & HawkME's checks, I've seen changes to mounting angle do this. Bad servo amp, also play in motor front bearing and/or RV.
Which axis gives the alarm?

Voltage peak-to-peak is actually the same, it's all about frequency and pulse width. Check out this video that is close to the what you'll see with ABB. Note that the 3-phase rectifier in the video is called converter/DC bus where ABB has historically called this the DC-Link.

-C202#EMH is dual without touch screen with according to my notes.
-
I don't list the -C212 versions in my notes and the CRC only lists it as -C212#Jxxx versions (Japan), mentions single and is special order. There doesn't appear to be any english versions available of the -C212 series or it's listed replacements.
My guess is the TP e-stop is single channel

That output is most likely is being turned on due to a weld schedule or process.
I feel your fixation on controlling DO[67] instead of adapting the weld I/O to match the digital I/O the welder expects is keeping you from an easy solve of this issue.
-
DO[67] not going to change if it's telling the welder to be in pulse mode.
Go to the digital outputs and turn DO[75] on & off and see if the wire feeds backwards.

Can you load it from the program menu of the teach pendant?
Looking at a backup, is it in the 'HOME' directory?
Never got a chance to use S4P+ RobView other than a few clicks on something already setup - can't help with job queries.
-
Wire stick is an input that comes from the welder. You can cross connect that input to the output you defined as described by SharplesR.
-
Have you gone to the robot's Weld I/O and configured the outputs to match the Intel notation? That's how the digital outputs appear to be configured.

I think i figured out how to release the brakes. I was able to move the U axis, but not the L.
Any tricks to get it to release? The bolts are barely long enough to reach in and start threading. Would a longer bolt be OK, or would it matter?
Thx.
Marty
The only way I know how to release the brakes is electrically. Not sure what bolts are for.
PLEASE NOTE: Releasing brakes is dangerous. Please make sure to think it thru and use something secure to limit axis motion if you must release them.

Possible to clean an encoder?
That is a job for professionals with specialized knowledge and tools with magnifiers in a semi-clean room environment. If it's dirty, it usually needs bearings, seals, etc.

I tried but could not remember the OR operator! I've always used & and + for the most part.
-
Uploaded some manuals.
Moving the position may help. The encoder may be getting hard to read at that spot or more likely the axis brake is weak allowing movement after power down.
