Setting the ramp time to 0 ms deactivates the function S curve and enables the use of
the linear ramps. The data set change-over of the parameters within an acceleration
phase of the drive demands the defined take-over of the values. The controller calcu-
lates the values required in order to reach the reference value from the ratio of the
acceleration to the ramp time and uses it until the acceleration phase is finished. With
this method, exceeding the reference values is avoided and a data set change-over
between extremely deviating values becomes possible.

Example: Calculation of the acceleration time in clockwise rotation at an accelera-
tion from 20 Hz to 50 Hz (fmax) and an acceleration ramp of 2 Hz/s for
parameter
Acceleration (Clockwise) 420. The parameter Ramp Rise
