Load Case Rotary Table

Feed constant

Advance of the load per revolution of the input shaft.

The following units are available:

• °/revolution (rotary motion at the load)

• Unit/revolution (rotary motion at the load)

Moment of inertia of the load

Mass moment of inertia of the load at the input shaft.

Kinetic Friction Torque

A torque that applies to the input shaft.

This parameter can have a positive value, or 0.

During movement (when velocity is different from 0) this torque acts opposed to the direction of the motion. The absolute value of the torque during movement is constant, independent of the velocity.

At stand-still (velocity =0), this torque does not occur.

A typical example for this type of torque is kinetic friction between solid bodies.

Additional constant torque

Static additional torque at the input shaft.

A positive value or negative value, or 0, is allowed. A positive value indicates that the torque applies in positive direction of the load. A negative value indicates that the torque applies in negative direction of the load.

The absolute value and the direction of the torque are constant and apply during motion and standstill. They are independent of the velocity.

An additional constant torque is caused, for example, by a suspended load.

Viscous friction torque

Velocity-dependent additional torque at the input shaft.

This parameter can have a positive value, or 0.

The absolute value of the torque is proportional to the absolute value of the velocity. The direction of the torque is opposed to the direction of motion.

A viscous friction torque is caused by the friction of a fluid.

Selected motion profile

The motion profile that is used a a basis for calculations for this axis.

Rotary motion (depending on the unit of the feed constant) at the load.

Selected load profile

The load profile that is used in combination with another motion diagram to define an additional load. It allows you to define a load that is exerted on a servo axis during specific sequences of motion.
