Motor
Stress to Cables
1) Avoid a stress application to the cable outlet and connecting portion by bending or self-weight.
2) Especially in an application where the motor itself travels, fix the attached cable and contain the extension
junction cable into the bearer so that the stress by bending can be minimized.
3) Take the cable bending radius as large as possible. (Minimum R20mm)
Permissible Load to Output Shaft
1) Design the mechanical system so that the applied radial load and/or thrust load to
the motor shaft at installation and at normal operation can meet the permissible
value specified to each model.
2) Pay an extra attention when you use a rigid coupling. (Excess bending load may
damage the shaft or deteriorate the bearing life.
3) Use a flexible coupling with high stiffness designed exclusively for servo application
in order to make a radial thrust caused by micro misalignment smaller than the
permissible value.
4) For permissible load of each model, refer to P.210, "List of Permissible Load to Output Shaft" of Supple-
ment.
Notes on Installation
1) Do not apply direct impact to the shaft by hammer while attaching/detaching a coupling to and from the
motor shaft.
(Or it may damage the encoder mounted on the other side of the shaft.)
2) Make a full alignment. (incomplete alignment may cause vibration and damage the bearing.)
3) If the motor shaft is not electrically grounded, it may cause electrolytic corrosion to the bearing depending
on the condition of the machine and its mounting environment, and may result in the bearing noise. Check
and verification by customer is required.
