P1.35.10 U/f Mid Voltg 0.0 100.0 % 100.0 605
Provided that the program-
mable U/f curve has been
selected (par. P3.1.4.1), this
parameter defines the mid-
dle point voltage of the
curve.
P1.35.11 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.
P1.35.12 StartMagnCurrent 0.00 Varies A Varies 517
Defines the DC current fed
into motor at start. Disabled
if set to 0.
P1.35.13 StartMagnTime 0,00 600,00 s 0,00 516
This parameter defines the
time for how long DC cur-
rent is fed to motor before
acceleration starts.
P1.35.14 DC Brake Current Varies Varies A Varies 507
Defines the current injected
into the motor during DC-
braking.
0 = Disabled
P1.35.15 DC BrakeTime 0,00 600,00 s 0,00 508
Determines if braking is ON
or OFF and the braking time
of the DC-brake when the
motor is stopping.
P1.35.16 DC Start Freq 0,10 10,00 Hz 1,50 515
The output frequency at
which the DC-braking is
applied.
P1.35.17 Load drooping 0.00 50.00 % 0.00 620
The drooping function
enables speed drop as a
function of load. Drooping
will be defined in percent of
nominal speed at nominal
load.
P1.35.18 Load drooping time 0.00 2.00 s 0.00 656
Load drooping is used in
order to achieve a dynamic
speed drooping because of
changing load. This parame-
ter defines the time during
which the speed is restored
to the level it was before the
load increase.
P1.35.19 Load drooping mode 0 1 0 1534
0 = Normal; Load drooping
factor is constant through
the whole frequency range
1 = Linear removal; Load
drooping is removed lin-
early from nominal fre-
quency to zero frequency
