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 installation 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 permissible value, which is designed exclusively for servo motors
with high mechanical stiffness.
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).
