8.2.1.4 Belt
1. Choose a belt that is suitable for the servo motor is allowable radial load and output
power.
2. When the motor accelerates or decelerates, the reaction force to the
acceleration/deceleration will increase the initial belt tension. Thus, when choosing a
belt, please consider the load of motion and the belt’s safety coefficient.
3. When installing the belt, suitably adjust the belt tension force and consider the
allowable radial load stated in the motor operating instruction. Please reference to
the following information.
