I would check the belt on the servo gun. Has the gun been autotuned lately? Ball screw lubricated? There is an offset parameter you can max inside $PARAM_GRP that would help you temporally if you needed a quick fix to run. If my hardware was ok, (belt) ball screw, ect.. I would attempt to autotune and monitor it from there.

This alarm is usually due to a bad brake or brake release power not being applied. Does the motor have a brake and can you verify it is releasing?

I have had an issue in the past with obara and degensha guns pressuring up on certain pressures and getting the error due to parameters not being met. A cable would be initial to look at especially if you get (stop excess errors). If it is one particular pressure, I would auto tune and re-establish new parameters for your gun if all hardware is functioning. Weld slag, grease and other debris have potential of getting inside the cover and causing the gun not to achieve it's distance with applied torque. I have seen this in the past due to a belt. I would def pop the cover off and inspect just to rule out.
