I'm very curious since I don't have a listing for DSQC345G, do you have the art. (part) number? I checked the ABB website for all 3HAB8101 numbers and couldn't find it.
If you have a DC4U rectifier, you may be able to use it if your software can select DC4 during an INIT start or query load. The amp portion can go unused but you may want to consider changing the dynamic braking resistors to handle the higher current capability.

Definitely try the battery pack first. Do this with the power on so you don't lose the rev. counters. Leave the controller on for 24 hours after installing the battery pack so the NiCad batteries fully charge.
If you need to replace the battery pack with the power off, move the robot to the sync (all axes at zero) position before turning off power. It's easier to update the rev. counters when you power it back on if it's already at sync.
Be very careful not to pinch any wires when you put the back plate back on the base of the robot.
The blanked out position numbers is normal on some of the software revisions when the robot is not calibrated - the numbers are meaningless until the robot is calibrated. -
Brakes get old and don't hold as well for many valid reasons especially when you factor in age.
Robots are designed to have tooling bolted to the flange which would counter the counter weight.
The brake board is located in the robot, the brake release switches are part of it.
The M96 IRB6400 Product Manual is very close to the M94A. Sheet 104 in the prints shows the brake board.

Since I can't take chances with customer's equipment, I ALWAYS change batteries with power on, never pull a CPU board without having a battery attached, always replace any batteries that measure less than their full rated voltage, and always bring extra batteries in case one is dropped/damaged.
Dating is important. I required our battery vendor to put "Installed Date" stickers on all the custom batteries we buy from them so there is a consistant place to date them. If there is no other place to put a date for new 'C' & 'D' cells batteries installed for robots, I'll write the date on the visible end of one of the batteries with a fine marker.

When releasing the deadman on the older 6000/6400 robots and if there was nothing mounted on the faceplate, sometimes there would be some upward motion. This is mostly due to the big counterweight not having any load to balance. Is there something mounted to the faceplate? If not, try mounting something heavier than 25Kg to the faceplate and try again.
The brake board in the robot has diodes that should keep induced voltage from the brakes. If you prefer to check, you can measure & monitor the voltage going to axis 3 brake at the brake board.

With some work, you can recover if you have a system backup. Post your problem in the ABB Robot Forum section.

Coordinated motion is a software option that is used to coordinate the motion of the robot with external axes.
What software version are you running and what kind of external axes is the robot controlling? -
Try searching for the Fanuc part #, 'A98L-0031-0012'.
If you prefer one from Fanuc, their CNC division (Fanuc America for me) is usually cheaper than the robotics division for parts common to both. -
There are several places in the E-Stop chain you can use. Rather than go into details, search the 'Installation and Commisioning' section of the product manual for both "Inspection before start-up" and "MOTOR ON / MOTOR OFF circuit" for detailed information. If you don't have the product manual, let us know what robot you have and someone will provide.

Google 'Tailored Blanks'. Lasers have been doing this for well over ten years for inner door panels.

I would look at axis 1 or 3 resolvers and duplicate, they are connected exactly the same. Attached is a PDF of the electrical for the resolver.

Are there any other errors that occur at the same time?
Was there something that happened when this error first started to appear?
Since this is an M98A, can we assume it is running RW3.2 with the 361/373 CPUs?
What is the revision of the software? Last revision of RW3.2 is rev.56. -
The battery pack provides enough energy for the controller to complete an image after the power is removed.
You can change it with the power off if you make sure you get a good image backup before change the battery pack.
To get an image before removing power, use 'Shutdown' located in the 'File' dropdown of the 'Service' menu.
Since this is a 18-cell NiCad battery pack, you need to leave the controller on for 24 hours after installation to ensure it is fully charged.
If you need to remove controller power before then, use the 'Shutdown' to be safe. -
Not sure which ArcMate 100 you have. The R-J2/R-J3 100i doesn't list a position for lifting the arm for a J1 RV change, but it should be close to the balanced upper arm / lower arm configuration used for transporting. Transportation section in manual says J2 @ -60 and J3 @ -15. I would practice attaching the slings (or chains) before disconnecting power to make sure they clear the robot, that way you can adjust the J2 & J3 positions before powering down. Luckily this is a small robot that is easier to work with. Don't forget to double-check that ALL the bolts are removed before lifting the arm off.

You can also make a copy of the BACKINFO directory and select it using the Update in RobInstall. It will create a keystr.txt file.

I will try to copy the disks to a PC, if it errors then you know where the problem is. If you have a bad floppy disk, which software and revision is it? If the disks copy good, it could be a problem with the floppy drive. Try cleaning the disk drive or if the you have another controller, swap disk drives to load software. Doesn't hurt to make fresh copies on new floppy disks either.

Don't be afraid to share details, you get faster & more relevant answers.
Is this the M94A with CommWare 2.0?
Are you having to update the rev. counters to recover? You can't move in world if you lose one of the rev. counters. Not exactly sure what you mean by "losing world position" and "re-calibrating".
Is this one axis, all axes?
What is it doing when this happens? -
Use a z offset with Lerak's time based feedrate. Distance/speed=time

Some robots and welders interface well together and others don't. What "older" robot do you have?

Had same problem 2 weeks ago.
Put a meter across the coil contacts of KM4 then try to jog.
You should see 24V soon as you move the joystick.
My problem was a loose wire on the KM4 coil (-).
