Hello Roboteers!
I wonder if anyone could send me some docs on IRB 90 robot. I spotted one that I could easily get to be my first robot. I am an engineer in a slightly different field.
I search through the forum and there is no mention of the IRB 90 at all. Maybe I could use docs from some other model that was produced at the same time (apart from IRB 6 I know about).
IRB 90 spec sheet & manual needed

The Irb90 was unique at the time in the ASEA (later ABB) range as it was built as a 6 axis machine so manuals for the smaller models (Irb6 & Irb60) would not help even though it used the same ballscrew drive for axes 2&3 system.
I should have paper documents for this model if you need any particular info but would have to scan each page so time would be an issue.
I've mostly worked on spot welding and press tending versions. -
Hello,
I visited the machine it has S2 Controls with two early Motorola chips. It looks it cant be easily interfaced to a pc (correct me if Im wrong). Given that the robot reads indeed ASEA and is 40+ years old I think there is an option to retrofit it with LinuxCNC. I have found info how to do it for IRB6/2. I need info on type and detailed specs of the joint mechanics and how different it is from IRB6/2. -
ASEA controllers up to and including S3 used their own language (ARLA) so cannot be easily interfaced with a PC.
Mechanically the Irb90 is very similar to it's smaller brothers, the Irb 6 & Irb60. Axis 1 is rotary, Axes 2&3 are driven by ballscrews, Axis 4 rotates the upper arm, finally Axis 5&6 (wrist bend & turn) are driven locally instead of the link rod system used on the smaller models.
All models use the same cabinet, control & feedback system, but the servo drives/amps just increase in capacity to suit the model. -
Do you plan on using the controller?
Hopefully, this was a running robot.
Already uploaded all my S2 manuals in PDF, like RoboWeld, any IRB90 manuals would be a hardcopy in a box somewhere - maybe. -
I tried to power up the robot using your S2 manual and did not succeed - the main processing board is bricked. The robot and the control unit are stored on two pallets - it seems for too many years. The arm has visually some signs of wear, but I was unable to properly test it. I will be looking for another one in a better shape and smaller. Thank you for your support.

There is so many thing little things that can keep the Main CPU from coming up and so many more that can keep the rest of it from running. Due to age, you would need to have access to an electronic repair facility just to replaced all the old out-of-tolerance capacitors. I would pass too even though I've fixed well over a hundred of these & rebuilt dozens more, they're just a lot of work to setup, maintain & program compared to a newer style. Can't let nostalgia override common sense. Good luck in your search.
