Rotational Move

Forced movement of a flange according to an angle, speed and angular acceleration signal

 Description The Rotational Move (or Move) component generates a forced angular position according to an input vector. The input vector has three components: position, velocity, and acceleration. They must be consistent with each other. These conditions do not apply to all applications. For example, if the position-dependent terms of a mechanical system are calculated only, you can provide $\mathrm{\phi }$ and set the angular velocity and the angular acceleration to zero. The Use Support Flange boolean parameter enables a support flange on the housing. When true (checked) the support flange must be connected in the drawing. When false the component is internally fixed to ground.
