1 = Automatic tor-
que boost
P2.6.3 U/f ratio selection 0 3 0 108
0 = Linear
1 = Squared

3 = Linear with flux
optim.
P2.6.4
Field weakening
point
8.00 320.00 Hz 50.00 602
The field weaken-
ing point is the
output frequency
at which the output
voltage reaches
the field weaken-
ing point voltage.
P2.6.5
Voltage at field
weakening point
10.00 200.00 % 100.00 603
The voltage at the
field weakening
point as a percent-
age of the motor
nominal voltage.
P2.6.6
U/f curve midpoint
frequency
0.00 P2.6.4 Hz 50.00 604
If the value of
P2.6.3 is program-
mable, this param-
eter gives the mid-
dle point frequency
of the curve.
