Scaling; Tolerance Band And Hysteresis - BONFIGLIOLI ACTIVE CUBE 201 Operating Instructions Manual

16.1.1.2 Scaling

The analog input signal is mapped to the freely configurable characteristic. The maximum admissible
setting range of the drive can be set via the frequency limits or percentage limits according to the
configuration selected. In the case of the parameterization of a bipolar characteristic, the set
minimum and maximum limits for both directions of rotation are effective. The percentage values of
the characteristic points are relative to the limits selected.
