Process sequence

The software module implements the "Rotary knife" function via the "Automatic" operating mode and generates a curve profile for an axis using the "nominal product length", "diameter", "number of tools", "synchronous angle", and "sync correction" (PI 10-14) parameters. After the synchronization, the axis then follows the selected master axis via an electronic cam. The curve profile generator is only active in operating modes 1400, 1401, and 1402.

During motion, recalculation of the curve can be started by changing the parameters "nominal product length" and "synchronous angle". The parameters "number of tools" and "knife diameter" may only be changed in an idle state and without enable. The modulo boundaries change in the process, which means that referencing is always necessary afterwards. The changeover to the new curve is carried out as soon as the curve end of the previous curve has been reached. Depending on the curve profile, fast acceleration may occur at the transition between curves.
