Hello, page 237: https://support.industry.siemens.com/cs/ww/en/view/109744610 Continuity at boundary points When assigning parameters to a cam object, you can make three different settings in the interpolation tab. These settings specify how the runtime system should handle discontinuity at the boundaries of the cam. The appearance of the cam in SIMOTION SCOUT may be different from when it is used later in the runtime system. ● Non-cyclic: Not constant at the boundary points The runtime system uses the cam as specified, including all discontinuities at the boundaries, even if it is applied cyclically. However, the acceleration limits and moment inertia of the mechanical system / drive are the governing factors. ● Cyclic absolute: Position-continuous in the boundary points The runtime system converts the cam in such a way that is position-continuous and velocitycontinuous at the boundaries during cyclic operation, which can cause changes to occur in the characteristic. ● Cyclic relative: Constant velocity in the boundary points The runtime system calculates the cam in such a way that is has constant velocity at the boundaries during cyclic operation - within mathematical limits, which can cause changes to occur in the characteristic |
