Code Parameter Min Max Unit Default ID Description
P3.1.2.1 Switching frequency 1.5 Varies kHz Varies 601
Motor noise can be mini-
mized using a high switch-
ing frequency. Increasing
the switching frequency
reduces the capacity of the
drive. It is recommended to
use a lower frequency when
the motor cable is long in
order to minimize capaci-
tive currents in the cable.
P3.1.2.2 Motor switch 0 1 0 653
Enabling this function pre-
vents the drive from tripping
when the motor switch is
closed and opened using
flying start for example.
0 = Disabled
1 = Enabled
P3.1.2.4 Zero frequency voltage 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.
