Hello.
We repaired the Y axis servo motor and when we installet it back, it has a disarrangement between the reading of the encoder and the motor.
One time, a mantainance company from another city repaired this by changing one parameter.
Now we changed the batteries and we are having the same problem with the original parameters.
We can't make HOME Return in Y axis. Nor to move JOG in Y axis.

401 servo alarm: vrdy off
424 servo alarm: Y detect err

Help, anyone knows wich is that parameter? or some another way to fix it?
Thanks
