Parameter descriptions
The characteristic can be adjusted via parameters 564 … 567 of the application.
The freely configurable characteristic enables setting a tolerance at the ends as well as a reversal of
the direction of rotation.
The following example shows the inverse reference value specification with additional reversal of the
direction of rotation. This is often used in pressure control systems.

The definition of the analog input characteristic can be calculated via the two-point form of the line
equation. The speed Y of the drive is controlled ac

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. 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.

419 Maximum Frequency 0.00 Hz 999.99 Hz 50.00 Hz
The control system uses the maximum value of the output frequency, which is calculated from the
Maximum Frequency 419 and the compensated slip of the drive mechanism. The frequency limits
define the speed range of the drive. The percentage limits complement the scaling of the analog input
characteristic according to the configured functions.
