8. Select language and press [OK]. Then enter the
motor data in parameters 1-20/1-21 through 1-25.
The information can be found on the motor
nameplate. The entire quick menu is shown in

9. For best results, skip 1-28 Motor Rotation Check at
this time until basic programming is complete.
This will be tested following basic set-up.
10. 3-41 Ramp 1 Ramp Up Time is recommended as
60 seconds for fans or 10 seconds for pumps.
11. 3-42 Ramp 1 Ramp Down Time is recommended
as 60 seconds for fans or 10 seconds for pumps.
12. For 4-12 Motor Speed Low Limit [Hz] enter the
application requirements. If these values are
unknown at this time, the following values are
recommended. These values will ensure initial
frequency converter operation. However, take any
precautions necessary to prevent equipment
damage. Make sure that the recommended values
are safe to use for functional testing before
starting the equipment.

13. In 4-14 Motor Speed High Limit [Hz] enter the
motor frequency from 1-23 Motor Frequency.
14. Leave 3-11 Jog Speed [Hz] (10Hz) at the factory
default (this is not used in initial programming).
15. A jumper wire should be in place between
control terminals 12 and 27. If this is the case,
leave 5-12 Terminal 27 Digital Input at factory
default. Otherwise select No Operation. For
frequency converters with an optional Danfoss
bypass, no jumper wire is required.
16. 5-40 Function Relay, leave at factory default.
This concludes the quick set-up procedure. Press [Status]

3.4 Automatic Motor Adaptation

Automatic motor adaptation (AMA) is a test procedure that
measures the electrical characteristics of the motor to
optimize compatibility between the frequency converter
and the motor.
•
The frequency converter builds a mathematical
model of the motor for regulating output motor
1(1)
current. The procedure also tests the input phase
Q2
balance of electrical power. It compares the
motor characteristics with the data entered in
parameters 1-20 to 1-25.
•
It does not cause the motor to run or harm to
the motor
•
Some motors may be unable to run the complete
version of the test. In that case, select Enable
reduced AMA
•
If an output filter is connected to the motor,
select Enable reduced AMA
•
If warnings or alarms occur, see 8 Warnings and
Alarms
•
Run this procedure on a cold motor for best
results
To run AMA
1. Press [Main Menu] to access parameters.
2. Scroll to parameter group 1-** Load and Motor.
3. Press [OK].
4. Scroll to parameter group 1-2* Motor Data.
5. Press [OK].
6. Scroll to 1-29 Automatic Motor Adaptation (AMA).
7. Press [OK].
8. Select Enable complete AMA.
