Generated force and load relation:

Static load: Initial position (0V position) is dropped

by spring constant but total displacement has the

same value under static load.

Spring load (Fluctuating load): Displacement

is changed by relation between generated

force and spring constant of actuator.

Static load: No load value change when actuator moves.

Fluctuating load: Load value changes by spring reaction when actuator moves.
