3.4 Automatic Motor Adaptation
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 startup. It
does not cause the motor to run or harm to the motor. For
best result, run the procedure on a cold motor.
To run AMA
1. Enter the motor name plate data in the frequency
converter, as described in 3.3.1 Basic Operational
Programming.
2. Connect terminal 37 to terminal 13.
3. Connect terminal 27 to terminal 12 or set
5-12 Terminal 27 Digital Input to No function.
4.
Activate the AMA 1-29 Automatic Motor
Adaptation (AMA).
5. Choose between complete or reduced AMA.
6.
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 into alarm
mode and the display shows that the user terminated the
AMA procedure.
Successful AMA
1.
The display shows Press [OK] to finish AMA.
2. Press [OK] exit the AMA state.
Unsuccessful AMA
1. The frequency converter enters alarm mode. A
description of the alarm can be found in
7 Troubleshooting.
2.
Report Value in the [Alarm Log] shows that 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 assists in troubleshooting. If contacting
Danfoss for service, make sure to mention
number and alarm description.
NOTE
Frequent
causes of unsuccessful AMA:
•
incorrectly registered motor name plate data
•
too great a difference between the motor power
size and the frequency converter power size
