BONFIGLIOLI ACTIVE Cube ACU 401-25 User Manual

15.1.1.2 Scaling
The analog input signal is mapped to the freely configurable characteristic. The max-
imum admissible setting range of the drive can be set via the fre
quency limits or
percentage limits according to the configuration selected. In the case of the parame-
terization of a bipolar characteristic, the set minimum and maximum limits for both
di
rections of rotation are effective. The percentage values of the characteristic points
are relative to the limits selected.

The control system uses the maximum value of the output frequency, which is calcu-
lated from the Maximum Frequency 419
and the compensated slip of the drive. The
frequency limits define the speed range of the drive, and the percentage values sup-
plement the scaling of the analog input characteristic in accordance with the func-
tions configured.

15.1.1.3 Tolerance Band and Hysteresis
The analog input characteristic with change of sign of the reference value can be
adapted by the parameter Tolerance band 450
of the application. The adjustable
tolerance band extends the zero passage of the speed relative to the analog control
signal. The parameter value (percent) is relative to the maximum current or voltage
signal.
