    hello member:
    1、if the servo motor have a fan ,check the fan is running normally.
    2、if the servo motor have a brake , check it by multimeter , the Insulation resistance and resistance are all right?
    3、check motor coil resistance is normal.
    4、the last: maybe the servo motor or servo amplifiers and cable are broken.
