5.4 System Start-up

Automatic motor adaptation (AMA) is a test procedure
which measures the electrical characteristics of the motor.
The AMA procedure optimizes compatibility between the
frequency converter and the motor. The frequency
converter builds a mathematical model of the motor for
regulating output motor current. The procedure also tests
the input phase balance of electrical power and compares
the motor characteristics with the data entered in
parameters 1–20 to 1–25. Run this procedure at start-up. It
does not cause the motor to run and it does not harm the
motor. For best result, run the procedure on a cold motor.
To run AMA
1. Enter the motor nameplate data in the frequency
converter, as described in chapter 5.3 Basic
Programming.
2. Connect terminal 37 to terminal 13.
3. Connect terminal 27 to terminal 12 or set
parameter 5-12 Terminal 27 Digital Input to [0] No
function.
4. Activate parameter 1-29 Automatic Motor
Adaptation (AMA).
5. Select either complete or reduced AMA.
Press [OK]. The display shows Press [Hand On] to

start.
7. Press [Hand On]. A progress bar indicates that the
AMA is in progress.
Stop the AMA during operation
Press [Off] - the frequency converter enters alarm mode,
and the display shows that the AMA procedure is
terminated.

The display shows Press [OK] to finish AMA.
Press [OK] to exit the AMA state.
The frequency converter enters alarm mode. A
description of the alarm can be found in
chapter 6.6 List of Warnings and Alarms.
Report Value in the [Alarm Log] shows the last
measuring sequence carried out by the AMA,
before the frequency converter entered alarm
mode. This number along with the description of
the alarm helps with troubleshooting. If
contacting Danfoss for service, make sure to
mention number and alarm description.
Incorrectly registered motor nameplate data.
Too great a difference between the motor
power size and the frequency converter power
size.
Press [Hand On] to provide a local start command
to the frequency converter.
Accelerate the frequency converter by pressing
▲
[ ] to full speed. Moving the cursor left of the
decimal point provides quicker input changes.
Note any acceleration problems.
Press [Off]. Note any deceleration problems.
Press [Auto On].
Apply an external run command.
Adjust the speed reference throughout the speed
range.
Remove the external run command.
Check the sound and vibration levels of the
motor to ensure that the system is working as
intended.
