Installation
Installation safety precautions for servo motor shaft
 When connecting the shaft, make sure that the required centering precision is reached.
If the shaft is not correctly centered, vibration may damage the bearings and encoder.
2
 When installing the coupling, do not apply excessive force to the shaft or the area around
the encoder, as the impact may damage the encoder.
 If the coupling makes any abnormal noise, realign the shaft until the noise disappears.
 Ensure the axial load and radial load are within the specifications. Refer to the
specifications for the maximum axial load (N) and maximum radial load (N) for each servo
motor.
 Use a bearing puller (D) to remove the motor shaft accessories (such as a coupling, gear
or belt pulley). Do not tug or apply excessive force.
