Thank you very much again. I've been able to move the servo!!

 But I'm receiving an error message and I have to restart the arduino board every time, disconnecting the USB cable.  If I press the reset arduino button, it doesn't work.

It works once and  I receive an error message when the servo is defined. After that I have to disconnect it again.

It's the same doing small or big movements.

a=10
ar = arduino();
b=20
myServo = servo(ar, "d9", "minpulseduration", 1.0e-3,  "maxpulseduration", 2.0e-3);
c=30
writePosition (myServo, 0);
d=40
position = readPosition (myServo)
pause(2);
writePosition (myServo, 1);

position = readPosition (myServo)

If I don't disconnect the board It doesn't work and I don't recieve the error message.

Disconnecting the board will put it out of sync in terms of any configuration it has done on the board, so perhaps isnt surprising that it shows an error at the case.

Modify your code to:

a=10
ar = arduino();
b=20
myServo = servo(ar, "d9", "minpulseduration", 1.0e-3,  "maxpulseduration", 2.0e-3);
c=30
writePosition (myServo, .5);
d=40
position = readPosition (myServo)
pause(2);
writePosition (myServo, .8);

position = readPosition (myServo)

And try it - I am still thinking you are possibly having issues from drawing too much power with the servo with the large movements and causing the board to reset.
