Cable: Stress Relieving
A
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.
B 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.
C Make the bending radius of cables as large as possible.
Permissible Shaft Load
A Make sure that both of radial and thrust load to be applied to the motor shaft during instal-
lation and running, becomes within the specified value of each model.
B
Pay extra attention at installing a rigid coupling(especially an excess bending load which may
cause the damages and/or wear of the shaft and bearings.
C Flexible coupling is recommended in order to keep the radial load smaller than the per-
missible value, which is designed exclusively for servo motors with high mechanical stiff-
ness.
D
For the permissible shaft load, see "Allowable Shaft Loads Listing" in Appendix.
Installation Notes
A
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).
B Try perfect alignment between shafts (misalignment may cause vibration, and damages
of the bearings).
