Function:
Selection of connected motor size in kW.
This data value is e.g. used for automatic
setting of other motor parameters 107-113.
Description of choices:
Read rated motor output in kW from the
motor’s type plate and select this value. If
this value deviates significantly from the
setting options, select the closest low or
high value (under- or oversize). The para-
meters 107-113 must then be optimized
manually with standard settings for motors
from 0.55-200 kW.
Value:
Only for 200-230 V units

Select the rated motor output (V) on the
motor plate.
Parameters 107-113 are changed auto-
matically.
All values can be addressed via the bus.
It is possible to select 440 V motor voltage
on a 400 V unit. This can be used to
optimise motor voltage on using e.g. a
440 V motor on 415 V mains voltage.
If the VLT
®
types 3060-3250 is factory set
to 500 V, so that the lowest motor voltage
which can be selected is 440 V, this can be
adjusted in parameter 650 by changing the
data values to the same VLT
®
type, but 400
V mains voltage.

Select the rated motor frequency (Hz) on the
motor plate. If a motor for 220/230 V
is connected to a 380/415 V frequency
converter, the default value (50 Hz) must be
changed to 87 Hz. Parameters 107-113 are
changed automatically.
