(5-12 Terminal 27 Digital Input
[0])
2.
Activate the AMT 1-29 Automatic Motor
Adaptation (AMA).

LC filter is mounted, run only the reduced AMT,
or remove the LC filter during the AMT
procedure.
4. Press [Ok]. The display shows “Press [Hand On] to
start”.

Unsuccessful AMT is often caused by incorrectly registered
motor name plate data or too big difference between the
motor power size and the frequency converter power size.
