in the manual.
• When you attach the key to the motor shaft, do not subject the key slot to
direct shock.
• When you attach the coupling, do not subject the shaft to shock.
When you attach the load, do not exceed the allowable value of the thrust load
or radial load specified in the manual or catalog.
• Although the tolerance for centering the coupling depends on the speed of the
motor and the type of the coupling, center the coupling within 0.03 mm. Also
refer to the coupling catalog for manufacturer requirements.
Even within this range, make adjustments to increase centering accuracy as
much as possible.
• If the coupling makes any abnormal noise, center the shafts again until the
noise is eliminated.
• Use a flexible coupling that is designed for Servomotors. We recommend that
you use a double-spring coupling, which provides some tolerance in eccen-
tricity and deflection angle.
