stability. It must also be taken into consideration that resonance effects such as these are

dependent on axis positions, for example. The parameterization selected must be stable in the

complete machining space of the machine. This is also the reason that using the function

without a direct measuring system (see Chapter "Active Vibration Suppression (APC without

sensor on the load side) (Page 556)") is frequently a more rugged solution.

Before the function can be optimized, the speed control loop must first be optimized as this

forms the subordinate controlled system.
