I'm troubleshooting an ABB 6400 m94.
I am getting Axis computer errors/DMA transfer error in robot computer/axis not commutated errors.
Several of the errors , when I look them up in the manual, say to replace the robot computer board.
I'm hoping someone can verify that this is referring to the Robot CPU / DSQC 335(or 326, ours is a 335).
also, there is no explanation or further information about the not commutated error , but could this be caused by a bad robot cpu? or could it be another separate issue?
