Hi.
I have a FR-V520 3.7Kw VFD that seems to have lost it braking.
I used to run the machine it is driving and when the motor stopped the rotating stopped dead.
Now I am getting error E0v3 described as "regenerative over-voltage shut-off during deceleration or stop".
I am now trying an external brake resistor but I get the same result. I have set parameter 30=1 and 70=10(%) like the manual describes but no braking.
Is it possible the internal brake transistor has failed.
I seem also to have not DC injection brake.Any thoughts?
