    "buzz" noise A axis motor after I replaced card

    Hello,
    I buyed a fadal with A axis... I found the A axis amplifier is burn.
    Inside cabinet I found other amplifier, I instaled it but now when I start machine (without moving A axis) I have a loud noise from A axis motor. I try haotic to turn small pots ) without any succces, just make the noise bigger.
    The good think the A axis is turning now using MPG, but I was scared to let the motor with this noise and try other adjustment without any documentation.
    Can you give me pleasca an advice regarding this situation?

    Best regards,
