Figure 7.6.21: Output Voltage Reduction with P.420 = 1
NOTE! the function can be enabled also through the digital inputs (see chapter INTERFACE, section Digital
inputs). In this case it will be possible to enable the Output Voltage reduction at any time the command
is applied.

Frequency Threshold
P.440 Frequency prog 1 (Frequency programmed 1)
Set point for the detection of the first frequency threshold.
The signalling of the frequency level detection can be programmed on the digital outputs.
P.441 Freq prog 1 hyst (Frequency programmed 1 hysteresis)
Defines a tolerance band around the Frequency prog 1 (P.440).
P.442 Frequency prog 2 (Frequency programmed 2)
Set point for the detection of the second frequency threshold.
The signalling of the frequency level detection can be programmed on the digital outputs.
P.443 Freq prog 2 hyst (Frequency programmed 2 hysteresis)
Defines a tolerance band around the Frequency prog 2 (P.442).
