Torque of the application

[7-164] Equation 3: Torque of the application

A consideration of the angle of tilt for the stationary torque currently is not yet included. For this the

torque has to be determined for each angle position.

Symbol Description

Radius of movement of the payload

• Path from the centre of rotation of the table to the supporting point of the payload.

• This radius is relevant for the inertia proportion of the payload. For the calculation one has to

think of the payload as a point mass. The mass of the payload is entered when the motion

profile is created.
