Changes from inverters to servos
(2) Size of the load inertia for motor axis conversion
In general, servos are more influenced by the size of moment of inertia of load than inverters.
If moment of inertia of load is too large compared to moment of inertia of motor, the motor axis will become easily affected by the load, and control will become unstable.
It is important to select appropriate servo capacities for the load of the mechanical system.
For stability, it is desirable that the magnification of moment of inertia of load (motor axis conversion) to moment of inertia of motor be lower than the recommended load to motor inertia ratio.

(3) Vibration to the motor axis
If a mechanical vibration is applied to the section where the motor is attached, the affect on the rotating motor shaft may be a problem.
Servo motors with built-in detectors require measures to reduce vibration.
(4) Skidding of the speed reducer mechanism
For V belt speed reducer mechanisms, countermeasures such as a timing belt become necessary to prevent from skidding that occurring in the belt section.
