5.8.1 Automatic Frequency Regulator Tuning (OLV Only)
The Automatic Frequency Regulator (AFR) is used to achieve stability when a load is suddenly applied or removed
by calculating changes in the torque current feedback, and adjusting the output frequency accordingly.
If the system is hunting, increase the OLV Stabilization Level (N02.05) by one until the load stabilizes. Both D03.02
and N02.02 will be incremented or decremented accordingly.
