reference from the minimum point (0 V / 0 mA / 4 mA or 10 V / 20 mA), and it will be directly related to the minimum
frequency set in P133. Check
If the parameter is set as Active (P230 = 1), the signal in the analog inputs will have a dead zone, where the frequency
reference remains at the Minimum frequency value (P133), even with the variation of the input signal. Check
9.2 on page 9-2.

Description:
These parameters define the analog inputs functions.
When the 0 option (Speed Reference) is selected, the analog input can provide the frequency reference for the
motor, subject to the specified limits (P133 and P134) and to the action of the ramps (P100 to P103). However, it
is also necessary to configure parameters P221 and/or P222 by selecting the analog input. For further details, see
