Troubleshooting the Autotune Procedure
If any errors are encountered during the Autotune process drive parameters are
not changed, the appropriate fault code will be displayed in the fault queue, and
the [Autotune] parameter is reset to 0. If the Autotune procedure is aborted by
the user, the drive parameters are not changed and the [Autotune] parameter is
reset to 0.
The following conditions will generate a fault during an Autotune procedure:
•
Incorrect stator resistance measurement
•
Incorrect motor flux current measurement
•
Load too large
•
Autotune aborted by user
•
Incorrect leakage inductance measurement Vector FV
