Servomotor Installation
•
The load mounting surface on the top and the fixed part on the bottom of a SGM7D-
I, -
J, or -
K Servomotor are coated with an antirust coating. Before you mount the Servo-
motor or load, use a hydrocarbon-based detergent and wipe off the coating completely. If the
coating is not removed completely, accuracy or functionality may be lost. When you wipe off
the coating, make sure that the coating or detergent do not come into contact with the cables,
interior of the Servomotor, or anything other than the load mounting surface and fixed part.
•
SGM7D-
L Servomotors have a connector box. Do not apply external force to the connector
box. Cables may become disconnected or the Servomotor may run out of control.
•
Make sure that the mounting screws do not penetrate any farther than the effective thread length in
the Servomotor. If the screws penetrate farther than the effective thread length, failure or reduced
functionality may occur.
•
When you couple the Servomotor to the load, ensure a centering accuracy of 0.01 mm or less. If
the centering accuracy is not sufficient, noise or vibration may occur and the bearings inside the
Servomotor may be damaged.
