MAX RPM DATA ERROR fault in parker AC690 drive - This fault comes when the MAX SPEED RPM is set to a value outside the range for which Autotune has gathered data. Autotune gathers data on the motor characteristics up to 30% beyond “max speed rpm”. 

1. If MAX SPEED RPM is later increased beyond this range, the drive had no data for this new operating area, and so will report an error.
2. To run the motor beyond this point it is necessary to re-autotune with MAX SPEED RPM set to a higher value.
