• Select a suitable size of coupling for the operating conditions.
A coupling that is too large or too small may cause damage.
• Rotate both shafts when you center the coupling.
• We recommend that you use a dial gauge to check the accuracy of cen-
tering, but if using one is not possible, slide the coupling along both
shafts and make adjustments so that it does not catch.
‹ Using a Belt
Select a belt that is suitable for the allowable radial load and output of the
Servomotor.
When the Servomotor accelerates or decelerates, the reaction force from
the acceleration/deceleration torque adds tension to the initial belt tension.
Consider this when you select a belt.
• When you attach the belt, adjust the belt tension so that the allowable
radial load given in the manual or catalog is not exceeded. For details,
refer to the catalog of the belt manufacturer.
