Mechanical Installation
‑30‑
● Use a dedicated flexible coupling. It is recommended to use a double leaf spring
coupling that allow a certain eccentric angle.
● To prevent malfunction, use a coupling with a proper size.
● Although the centering of the coupling varies with the rotating speed and the type
of the coupling, ensure that the coaxiality of the load at both ends of the coupling
is < 0.03 mm.
Belt connection
● Select the appropriate belt according to the allowable radial load of the servo
motor and the output power of the motor.
● When installing the belt, ensure that its tension is lower than the specified
allowable radial load.
● See the instructions of the belt manufacturer for detailed installation precautions.
