When you jog the axis does it move smoothly and quietly? Any grinding noise or jerkiness? Other than that, if there are any loads mounted on the arm they should be defined as armloads in the moc.cfg. Any loads such as the end effector and payload, if any, should be properly identified.
All axis move smoothly when it in jog mode.
Ultrasonic welding horn mounted on arm.
Can u discribe where the Moc.cfg available and how to setup it.
The MOC is part of your system parameters. You should read up on it in the system parameter manual. You can find that in robotstudio using the help button found on the file tab.

Hello,
Under normal circumstances, such errors are not expected from the 3th axis.
Those that may cause errors;
-3th axis Resolver Angle is in the wrong angle,
-Resolver Angle Adjustment at very close angles,
-3th axis Resolver itself is now broken,
-Unable to read 3th axis resolver angle on SMB card, card malfunction,
-Incorrect reading of the 3th axis motor value of the Axis Computer card on the controller, failure of the card,
-Maybe it will be the simple method, but reinstalling the system sometimes works.
- Deformation of cables, breakage of resolver cables, failure to transmit.
-3th axis being overloaded, strained, itchy, bearing become unusable, oil-free operation, oil change time has passed, oil becoming unusable
- engine warming up
-The brakes do not hold as before, the pads run out, they cannot maintain their current position.
Mov L instruction
point replace with Mov J instruction.
I guess it is just a wrongly defined mass in tooldata or load when gripped something.

No that won't solve a triggered MotionSupervision.
Check what your "Motion Supervision on Path" is set to?
In the flexpendant Control Panel -> Supervision
This is possibly the servo brake failing, this has happened twice on my ABB robots on a rotate axis, generally on a start up after a period of idleness (not necessarily a long period) , once reset, all subsequent operations were fine. It involved replacing the servo motor completely as they are not servicable.
