NOTE
•
For the best adaptation of the frequency converter,
run AMA on a cold motor
•
AMA cannot be performed while the motor is
running
NOTE
Avoid generating external torque during AMA.
NOTE
If one of the settings in ameter group 1-2* Motor Data is
changed,
to
, the
advanced motor ameters, will return to default setting.
This ameter cannot be adjusted while the motor is running.
NOTE
Full AMA should be run without filter only while reduced
AMA should be run with filter.
See section:
Application Examples > Automatic Motor
Adaptation
in the Design Guide.
3.3.3 1-3* Adv. Motor Data
ameters for advanced motor data. The motor data in
to
must match the
relevant motor in order to run the motor optimally. The
default settings are figures based on common motor ameter
values from normal standard motors. If the motor ameters
are not set correctly, a malfunction of the frequency
converter system may occur. If the motor data is not known,
running an AMA (Automatic Motor Adaptation) is
recommended. See the
Automatic Motor Adaptation
section.
The AMA sequence will adjust all motor ameters except the
moment of inertia of the rotor and the iron loss resistance

The table shows the number of poles for
normal speed ranges of various motor types.
Define motors designed for other frequencies
separately. The motor pole value is always an
even number, because it refers to the total
number of poles, not pairs of poles. The
frequency converter creates the initial setting
of

Motor Frequency
and
Motor Nominal Speed

This parameter cannot be adjusted while the
motor is running.
