Unsuccessful AMT
1.
The frequency converter enters into alarm mode.
A description of the alarm can be found in the
Troubleshooting
section.
2.
"Report Value” in the [Alarm Log] shows the last
measuring sequence carried out by the AMT,
before the frequency converter entered alarm
mode. This number along with the description of
the alarm will assist you in troubleshooting. If you
contact Danfoss Service, make sure to mention
number and alarm description.
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.
