Cable: Stress Relieving
• Make sure that the cables are not subjected to moments or vertical loads due to external
bending forces or self-weight at the cable outlets or connections.
• In case the motor is movable, secure the cable (proper one supplied together with the
motor) to a stationery part (e.g. floor), and it should be extended with an additional cable
which should be housed in a cable bearer so that bending stresses can be minimized.
• Make the bending radius of cables as large as possible.
(Minimum bend radius: 20 mm)
Permissible Shaft Load
• Make sure that both of radial and thrust load to be applied to the motor shaft during instal-
lation and running, are within the specified value of each model.
• Pay extra attention to installing a rigid coupling (especially an excess bending load which may
cause the damages and/or wear of the shaft and bearings).
• Flexible coupling is recommended in order to keep the radial load smaller than the permis-
sible value, which is designed exclusively for servo motors with high mechanical stiffness.
• For the permissible shaft load, see "Allowable Shaft Loads Listing" in Appendix.
Installation Notes
• Don't hit the shaft with a hammer directly while
attaching/detaching the coupling to the motor
shaft.(otherwise the encoder at the opposite
end of the shaft will be damaged).
• Try perfect alignment between shafts (misalignment may cause vibration, and damages of
the bearings).
