-17-Cable: Stress Relieving• Make sure that the cables are not subjected to moments or vertical loads due to externalbending forces or self-weight at the cable outlets or connections.• In case the motor is movable, secure the cable (proper one supplied together with themotor) to a stationery part (e.g. floor), and it should be extended with an additional cablewhich 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 maycause 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 whileattaching/detaching the coupling to the motorshaft.(otherwise the encoder at the oppositeend of the shaft will be damaged).• Try perfect alignment between shafts (misalignment may cause vibration, and damages ofthe bearings).Before UseM o t o r
