D Precautions when Connecting with the Coupling
Take the following precautions when connecting the Resolver to the machinery via the Coupling.
• Make sure the axle center does not protrude into the area marked C in the diagram. If the axle center is
protruding when the Resolver rotates, the Coupling will no longer function and the machinery may be
damaged.
• If the bend angle or displacement of the axle center is large, the life of the Coupling will be shortened
and the accuracy of the Resolver rotation angle will be adversely affected.

H Connecting without the Coupling
Give sufficient consideration to the load that will be applied to the Resolver axle if it is connected to the
machinery without the Coupling. Make sure the applied load will be below the rated load.
