Hello,
I have the problem with the Fanuc ARC Mate120iD robot (2021.).
DTERR alarm (Grp:1 Ax:2).
We replaced the encoders and again the error is on the Ax:2.
We checked the safety fuses and they are fine.
The cables look fine.
What do you think? On the forums, I find I lot about that error but nothing specifically, everything is about encoders, cables and connectors, batteries, and servo amplifier....
The robot works every day, and now he just decided to stop.
