Code Parameter Min Max Unit Default ID Description
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 parameter 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 linearly from nominal frequency
to zero frequency
5.3.6 Motor potentiometer application
Use the Motor potentiometer application for the
processes where the frequency reference of the
motor is controlled (that is, increased and decreased)
through digital inputs.
In this application, the I/O terminal is set to the default
control place. The start/stop commands are given
with DI1 and DI2. The frequency reference of the
motor is increased with DI5 and decreased with DI6.
It is possible to configure all the drive outputs freely in
all the applications. There are 1 analogue output
(Output Frequency) and 3 relay outputs (Run, Fault,
Ready) available on the basic I/O board.

0 = No reset
1 = Reset if stopped
2 = Reset if powered down
P1.36.3 Preset Freq 1 P1.3 P1.4 Hz 20.0 105
Make the selection of a preset frequency
with the digital input DI4 and DI5.
