Connecting the Servomotor and Machine
‹ Using a Coupling
• Use the key that is provided with the Servomotor or a key of the size
specified 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
eccentricity and deflection angle.
