Servo Motor Humming

[gcastro]

What could be the possible causes for a humming servo motor ?
I am new in the field and if you need more details please ask.

Thank you

Is it a DC or an AC servo?

IT SOUNDS LIKE YOUR GAINS ARE SLIGHTLY TO HIGH, ON YOUR
AMPLIFIER DRIVE REDUCE PROPORTIONAL OR INTEGRAL GAIN THIS CAN BE A COMMON FAULT.MAKE ANOTE OF THE SETTINGS INCASE
ALSO THE ADJUSTMENT SHOULD BE DONE WITH A SCOPE BUT YOU CAN DO IT WITHOUT ONLY MAKE A VERY SMALL ADJUSTMENT.
