Dear Gsmaster,
One option regarding brake of axis 2, you can swap the entire motor (with it's brake) with the one at axis 1, due to the fact axis one brake is suffering much less work/stress and both are the same model.
I hope it would help you.
Best Regards.

Hi everybody,
Floppy DD's arrived and we were able to format them, so the floppy drive works as desired. And now we are desperated, nobody at Volkswagen seems to be able to help us....does anybody know where we can have a key floppy disk for system 1.13n?
Thanks !!
Hi Andreas,
Sorry for my late reply. Part of the problem is solved. We couldn't calibrate it because we couldn't enter "Hand mode". And the reason why was a blown track on the teaching console board. Once it was repaired, we could enter "Hand mode" and try different settings; the problem we are facing now is the floppy is not working as resired, very strange (cannot format is PDOS or MSDOS). Waiting for some DD floppies is order to check it again.
Best Regards.
I have it !! I'll read it and see if something is said regarding my issue.
Thank you for your help, really apreciated !!!!

Hello everybody,
I cannot enter "hand mode" and I have a message on display saying that I have to calibrate axis 1. Is it possible to calibrate the axis without entering "hand mode"?
Thanks in advance, I'm a stuck and desperated....
Best regards !!
I have the same problem. What is curious is that we have 2 Kuka robots and 1 SEF rack. If we connect the first robot we cannot enable the "hand" mode (logically, other modes are not working). If we connect the second robot we have de VRS1 logo screen and nothing else....does anybody what could be happening with the second Kuka robot that locks the system such this way?
Thank you very much !!!
Hello KKKUB,
I have asimilar problem, I have this message and I cannot change into "Manual" mode. Did you solve the problem?
Thanks !!
Hi again,
Reading the VRS1 programming manual it says something that, if hand mode is not possible, it means there is a problem, check the Operating Manual. Does anybody which is this manual?
On the other hand we are considerating taking out all the "brain" and leave the controllers (M14 and M15 with the Sinudyn power supply) and hardware (the robot itself). Has anybody done this before? If affirmative, does anybody know which "brain" (PLC or whatever) they used?
Sorry for disturbing (it's getting desperating) and thanks for helping !!

Hi,
Thanks for replying and sorry for creating the thread at the wrong forum.
Here it's a picture of the robot.
Danke !!
Hi,
My name is Gustavo. We have recently bought an old VK120, it was working until it was sold.
It's has a VRS-1B hand console. Software version I think is 1.13.
The robot was uninstalled by the seller, we setup all connections at our facilities. The system starts and shows the attached error. It seems is asking for calibrating axis 1 but, after enabling the system (green light on after pressing the 2 "enable" buttons), no button functions; we pressed the "hand" and then other buttons but nothing.
We think it's a silly thing but reading the programming manual we found nothing that helped us (for sure the answer is there....). If you have any idea that could help us it would be great !!
Sorry for disturbing, we are new in robotics and here in Mallorca few people with this knowlege or robots working around 
.
Due to the fact that hugue information it's in german, Ich lerne Deutsch .
Thank you, Danke sehr !!
