The time set at AP2-39 refers to the absolute time that it takes for the pump to decelerate from the
frequency set at AP2-38 to the frequency limit set at ADV-25.
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).
