The input signal v_ref defines the reference speed in [m/s]. Flange flange is forced to move relative to the support connector according to this reference motion. According to parameter exact (default = false), this is done in the following way:
The input signal can be provided from one of the signal generator blocks of the block library Modelica.Blocks.Sources.
Description: = true, if support flange enabled, otherwise implicitly grounded
Description: Is true/false for exact treatment/filtering of the input signal, respectively
Type: Frequency (Hz)
Description: If exact=false, critical frequency of filter to filter input signal
