5.17 Load Tuning
Load tuning refers to an operation that detects the load applied to a specific section of the
inverter operation (current and voltage) and creates an ideal load curve for the under load
and pump clean operations. The two set points to define the section are user-definable, and
are set at 50% and 85% of the base frequency (DRV-18 Base Freq) by default. The load
tuning result values are saved at codes AP2-2–AP2-10. These values are user definable as
well.
The minimum set point for the load tuning begins at 15% of the base frequency (DRV-18
Base Freq), and the maximum set point can be set up to the base frequency. If the
frequency limit is set to ‗1 (Yes)‘ at ADV-24 (Freq Limit), the range is limited within the
frequencies set at ADV-25 (Freq Limit Lo) and ADV-26 (Freq Limit Hi).
