tc429 we tried that with the parameter 8121 to 0 the vibrations are still there,
we check even before the coupling and the center bolt of the encoder and we check again now there is nothing loose,
we even swap the servo motors so right now the motor from Y axis is on the X axis and vice versa,
we also swap the motor cables and the encoder cables result is the same vibration on X axis
that's why we suspected that the axis board A16B-2200-0360/03B may be bad especially because
the vibrations are by our opinion related to the M34/M35 connectors.
When we swap the parameter 0269 to 2 which means that the M34/M35 control the Y axis
and parameter 0270 to 1 which means that the M37/M38 cotrol the X axis,
the vibration goes to Y axis but stays on the M34/M35 conectors of the axis board.
this is why we think that the axis board is bad but we are not completely sure so if there is something else that we can try we are open for suggestions,
we can't try the axis board on other machine because there is no other machine in nearby with that 0m-C control to check for sure,
also we don't have fanuc service in our country so we would like to be sure as possible before we buy or pay for repair of the axis PC board.
we are open for suggestions if did something wrong so far or what to do next...
