system instability and may damage the motor shaft. All connections 
between the system and the servo motor shaft must be rigid to achieve 
acceptable response from the system. Periodically inspect connections to 
verify their rigidity. 
When mounting couplings or pulleys to the motor shaft, ensure that the 
connections are properly aligned and that axial and radial loads are within 
the specifications of the motor. Refer to Motor Load Force Ratings on 
page 13 for guidelines on how to achieve 20,000 hours of motor bearing 
life. 
Preventing Electrical Noise
ElectroMagnetic Interference (EMI), commonly called noise, may 
adversely impact motor performance by inducing stray signals. Effective 
techniques to counter EMI include filtering the AC power, shielding and 
separating signal carrying lines, and practicing good grounding 
techniques. 
Effective AC power filtering can be achieved by using isolated AC power 
transformers or properly installed AC line filters.
ATTENTION
!
Damage may occur to the motor bearings and the 
feedback device if sharp impact to the shaft is 
applied during installation of couplings and pulleys. 
Damage to the feedback device may result by 
applying leverage from the motor mounting face to 
remove devices mounted on the motor shaft. 
Do not strike the shaft, couplings, or pulleys with 
tools during installation or removal. Use a wheel 
puller applying pressure from the user end of the 
shaft to remove any friction fit or stuck device from 
the motor shaft. 
Failure to observe these safety procedures result in 
damage to the motor and its components.
