Mounting to the Machine

Important

 Confirm that the rotating part and fixed part of the Servomotor have not been reversed when
you mount the Servomotor to the machine.
Important Precautions for All Servomotors
•
When you mount the Servomotor to the machine, use the flange outer diameter to center the
Servomotor and the machine.
•
When you couple the Servomotor to the load, sufficiently center the output shaft with the load.
Consult your Yaskawa representative if you plan to use a rigid coupling with the machine shaft.
Important Precautions for SGM7D Servomotors
•
Attach the load securely with screws to the load mounting surface on the top surface of the
Servomotor. Provide a gap of 1 mm or greater between the top of the Servomotor and the load
and make sure that the load does not come into contact or interfere with any parts other than the
load mounting surface. If there is any such contact or interference, mechanical accuracy will be
reduced. Also, make sure that the Servomotor mounting surface has a flatness of 0.01 mm min.
Otherwise, the accuracy or performance of the Servomotor may be affected.

•
Do not exceed the tightening torques given in the following table for the mounting screws of the
rotating part and fixed part of the Servomotor. If you tighten the screws to an excessive torque, the
screw threads may be damaged and the Servomotor may fail.

•
Use Loctite 601 or the equivalent for the mounting screws to prevent loosening.
•
If you place anything through the hollow hole, allow a clearance of at least 1 mm on all sides and
make sure that nothing comes into contact with the inside surface of the hollow hole. Do not press
anything into the hollow hole or apply pressure. Accuracy and functionality may be lost and failure
may occur.
