Determination of the dynamic response limiting values

In addition to determining the natural frequency of the path axes for assigning parameters to
the axis-specific limit frequencies (MD32440 $MA_LOOKAH_FREQUENCY), the
implementation of the "adaptation of the dynamic path response" function also requires
dynamic response limits to be determined for velocity, acceleration and jerk.
