Hi,
I have 2 robot units of the same model (2000iB/200T) with R30iB controllers (V8.30). From the previous team, controller (A) had corrupted files and had to re-imaged from another controller (C) which its no longer in the production floor but from what I heard its the same robot model. When they finished commissioning controller (A), they just re-imaged controller (B) from controller (C) just like they did on controller (A).
When the robot units was handed off to our team, they provided only 1 USB Software Card for both controllers (A & B).
I had to install the password protection option on both of the controllers, and they took the same PAC code for both. Installation was successful for both, however, upon starting up the robots, both of them started to give me errors on SRVO-050 (Collision Detection on Axis 3). I reduced the collision detection sensitivity and currently they are running.. (Coll Detect was 150% and reduced to 100% - previously it was running fine at 150% Coll Detect sensitivity) but my question is why? nothing was modified on controller A and controller B when installing the password protection option. I called Fanuc and they could not provide a straight answer on this, they just told me to check the maintenance data to see if the robot was setup to be on the floor, side wall or upside down. I checked the Maintenance settings (CTRL Start --> MENU --> MAINTENANCE --> MANUAL) but nothing was changed.
