1.1.5 Servomotor Handling Precautions

Align the center when connecting with the machine system. Use a flexible coupling.
Use rigid one designed exclusively for servomotors whenever possible.

Do not use a rigid coupling which does not allow errors between shafts.
Otherwise mechanical vibration will be caused, resulting in damaged bearings and/or shorter
service life.

Do not supply commercial power directly to the servomotor. It will cause burnout.
Test run with commercial power also shall not be performed.
1.1.6 Notes on Stress Given to Cable
 In applications where the servomotor and machine movable part move, take measures to avoid
stress given on the cable.

Route the encoder cable and motor power cable in CABLEVEYOR.
 Fix the encoder cable and motor power cable attached to the servomotor (routed from the motor)
with cable clamps or similar.

Design the radius of bend as large as possible.
 Do not allow bending stress or stress caused by the self weight, at joints of the cable.
Do not hammer

Do not give a strong impact on the output shaft of the servomotor.
Otherwise the encoder inside the motor will be broken.
