631
The automatic motor identifica-
tion calculates or measures the
motor parameters that are
needed for optimum motor and
speed control.
0 = No action
1 = At standstill
P3.1.2.5
Magnetizing current
0.0

A
0.0
612
Motor magnetizing current (no-
load current). The values of the
U/f parameters are identified by
the magnetizing current if given
before the identification run. If
this value is set to zero, magne-
tizing current will be internally
calculated.

Enabling this function prevents
the drive from tripping when the
motor switch is closed and
opened e.g. using flying start.
0 = Disabled
1 = Enabled

The drooping function enables
speed drop as a function of load.
Drooping will be defined in per-
cent of nominal speed at nomi-
nal load.
P3.1.2.8
Load drooping time

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.
P3.1.2.9
Load drooping mode
0

0 = Normal; Load drooping fac-
tor is constant through the
whole frequency range
1 = Linear removal; Load droop-
ing is removed linearly from
nominal frequency to zero fre-
quency

666
The drive searches for the mini-
mum motor current in order to
save energy and to lower the
motor noise. This function can
be used e.g. in fan and pump
applications
0 = Disabled
1 = Enabled

Overmodulation
0

1
Maximizes drive output voltage,
but increases motor current
harmonics.
