General remarks about functions of this firmware
This firmware is suitable, together with motrona controllers of type MC700 or MC720 and an
appropriate servo drive, to generate and control an optimized speed profile for rotary guillotine
cutting systems.

These cutting systems require the horizontal speed of the cutting tool to be synchronous to the
material at any time of the penetration of the tool, whereas outside of the penetration zone, it
is the cutting length and the active radius of the rotation that determine the speed profile.
The subsequent drawing explains the principle of a rotating puncher, the principle of a rotating
shear, and also the geometric basis of the process. It is easy to understand that, during the
penetration of the tool, both applications require an angular correction of the rotational speed,
as soon as the difference between the inner radius ri and the outer radius ro is no more
negligible.
