Is there actually anything mounted on any of the arms? I meant to ask what the robot does, material handling, spot welding?

Do you know if the payloads and arm loads have been properly set up?

What do those robots do that retrace the path some? Do they carry a heavy load? Is the error something like a path regain error? There is a system parameter for Path regain distance. If they have deviated outside of the defined distance, they will not recover automatically. It is for safety.

Most of my experience is with ABB robots and, consequently, the Rapid programming language. One may use the editor in robotstudio, even loading programs into the virtual controller to get syntax checking and such. Other than that, one may use any ascii based text editor. I have used Ultraedit for many years, but even notepad will work. Additionally, one may connect to the controller with Robotstudio to directly edit the rapid program loaded into the controller. Teach pendant programming is a good skill to have as well. I have known many programmers who could do one or the other well, but not both. My take is that what would you do if you were on the road and your laptop broke? Better be able to use the pendant!

If I recall correctly, that manual mentioned above has a timing chart which will pretty much lay out how to start the robot. Personally, I do NOT like STartMain system input, it makes recovery much more difficult.

You mentioned that both robots are near enough to touch each other. That also means that operating one could allow someone else nearby to be struck if both are in teach mode. I have seen some safety setups where this was not allowed. In these setups, in order to move one robot in teach the other must be in auto mode. Let us know if this changes anything.

Create the system from backup in RS. Then you should be able to remove that option. One may always remove options, but never add without a new keystring. Then you can download that modified system and select it using X-Start. Make backups first!

Restart the controller. Does it allow you to move and run the robot anyway?

Have you A) restarted the robot? and B) turned the motors on after restart? World zones are not recognized until the first motors on after a restart when they have been properly configured.

You should look to the manuals and tools sub forum to download the system parameter manual for the armload parameters. Then, Instructions, functions and datatypes manual for information on tooldata.

These are things that can cause premature failure if they were not set up properly.
-
What are the payloads and armloads? Have they been properly entered in the tooldata and armload parameters?
-
Are the armloads and payloads properly defined?
