Table 62. Open loop settings
Code Parameter Min Max Unit Default ID Description
P3.1.4.1 U/f ratio 0 2 0 108
Type of U/f curve between zero
frequency and the field weaken-
ing point.
0=Linear
1=Squared
2=Programmable
P3.1.4.2 Field WeakngPnt 8.00 P3.3.1.2 Hz Varies 602
The field weakening point is the
output frequency at which the
output voltage reaches the field
weakening point voltage
P3.1.4.3 Voltage at FWP 10.00 200.00 % 100.00 603
Voltage at field weakening point
in % of motor nominal voltage
P3.1.4.4 U/f Mid Freq 0.00 P3.1.4.2 Hz Varies 604
Provided that the programmable
U/f curve has been selected (par.
P3.1.4.1), this parameter defines
the middle point frequency of the
curve.
P3.1.4.5 U/f Mid Voltg 0.0 100.0 % 100.0 605
Provided that the programmable
U/f curve has been selected (par.
P3.1.4.1), this parameter defines
the middle point voltage of the
curve.
P3.1.4.6 Zero Freq Voltg 0.00 40.00 % Varies 606
This parameter defines the zero
frequency voltage of the U/f
curve. The default value varies
according to unit size.
P3.1.4.7 Flying Start Options 0 1 0 1590
Check box selection:
B0 = Search shaft frequency from
same direction as frequency ref-
erence.
B1 = Disable AC scanning
B4 = Use frequency reference for
initial guess
B5 = Disable DC pulses
