Unsuccessful AMA
1. The frequency converter enters into alarm mode. A
description of the alarm can be found in the Trouble-
shooting section.
2. "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 will
assist troubleshooting. If contacting Danfoss Service,
make sure to mention number and alarm descrip-
tion.
NOTE
Unsuccessful AMA is often caused by incorrectly entered
motor name plate data or too big difference between
the motor power size and the frequency converter
power size.
