elapses, accelerates by the acceleration time set at AP2-22, and operates at the frequency set at
AP2-25. The pump runs for the time set at AP2-24, decelerates by the time set at AP2-23, and then
stops. This operation repeats in the forward and reverse directions (one after another) for the
number of times set at AP2-28 (PC Num of Step). Each time the steps (Fx/Rx) switch, the inverter
waits at a stop state for the time set at AP2-21 before going on with the next step. One step in the
forward direction and another step in the reverse direction makes one cycle. The number of pump
clean cycles is set at AP2-30. In the figure above, AP2-28 is set to ‘1’, and AP2-30 is set to ‘1’.
Pump Clean Function Setting Details
Code Description
AP2-15 PumpClean Mode
Sets the pump mode.
Setting Function
0 None Pump Clean function is not used.
1 DI
defendant
Set one of the terminal inputs to ‘46 (Pump
Clean Sel)’ and performs the pump clean
operation by turning on the terminal.
2 Power Performs a pump clean operation when a
pump consumes more power than it is
supposed to consume in a normal operation.
3 Current Performs a pump clean operation when a
pump consumes more current than it is
supposed to consume in a normal operation.
AP2-16 PumpClean Sel
Sets the pump clean start mode.
Setting Function
0 None Pump clean is performed only by the
function set at AP2-20.
1 Start Pump clean is performed each time the
inverter starts operating.
2 Stop Pump clean is performed each time the
inverter stops operating.
3 Start & Stop Pump clean is performed each time the
inverter starts or stops operating.
AP2-17 PC Curve Rate
AP2-18 PC Curve Band
AP2-19 PC Curve DT
If AP2-15 is set to ‘Power’ or ‘Current,’ multiply the load
characteristic curve set at AP2-2–AP2-10 by the value set at AP2-
17 (100[%]+AP2-17[%]), and reset the load characteristic curve for
the pump clean operation (refer to the load tune features for AP2-
2–AP2-10 setting values).
Apply (rated inverter current x AP2-18 setting value) and (rated
