Unsuccessful auto tune
1. The frequency converter enters into alarm mode. A description of the alarm can be found in the Warnings and Alarms chapter.
2. "Report Value” in the [Alarm Log] shows the last measuring sequence carried out by the auto tune, before the frequency converter entered alarm mode.
This number along with the description of the alarm will assist you in troubleshooting. If you contact GE for service, make sure to mention number and
alarm description.
NB!
Unsuccessful auto tune is often caused by incorrectly entering motor name plate data or a too big difference between the motor power size and the frequency
converter power size.
