The direction of rotation is the only operation control that depends
on other parameter for operation - P231.
For more details, refer to Items 6.2.4, 6.2.5 and 6.2.6.

The analog inputs AI1 and AI2 define the inverter frequency reference
[ 1.00 ]
as shown in the curve below.
0.01
Figure 6.17 - Determination of the frequency reference from the analog
Note that there is always a dead zone at the starting of the curve
where the frequency reference remains at the value of the
minimum frequency (P133), even when the input signal is changed.
This dead zone is only suppressed when P133=0.00.
