pid tuning Estun servo motor

Greetings, I'm in a conversion, I'm in the PID tunig phase, I have the default configuration. everything in zero. I put any value from 1 to 10 in P. but the engine moves it to a position and when it stops it remains with a vibration and generating a buzz.

The machine moves the two axes.

I have converted two machines of equal size. It is the first time I use ESTUN servomotor. the first two have used the original servos siemens. and I have started the PID tunig in the same way. which John advises, go up P until stability is lost and then return. but never generated that vibration and that buzz.

The servo motor is EMG-50AP22, 5kw, 2000rpm, 28A, 23.9Nm, AC200V.
the driver = PRONET-E-50A.

Any suggestion is welcome.

the pronet may have a external preenable pin to set off the buzz
