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
motor x AP2-18 setting value) to the pump clean load curve
calculated by AP2-17 to calculate the final pump clean load
curve. The inverter performs pump clean operation when the
inverter continues operating for the time set at AP2-19.
AP2-20
Clean Start DT
When AP2-15 is set to ‘Power’ or ‘Current’, a pump clean is
performed if the inverter operation power or current stays above
the pump clean load characteristic curve (defined by AP2-17 and
AP2-18) for the time set at AP2-19.
AP2-21
Clean Step DT
Sets the time for the inverter to maintain 0 speed (stop) before
the inverter switches from forward to reverse operation during
pump clean.
AP2-22 PumpClean AccT
AP2-23 PumpClean DecT
Sets the Acc/Dec times for pump clean operations.
AP2-24 Fwd Steady Time
AP2-26 Rev Steady Time
Sets the time to maintain forward and reverse operations.
AP2-25 Fwd SteadyFreq
AP2-27 Rev SteadyFreq
Sets the forward and reverse operation frequencies.
AP2-28
PC Num of Steps
Determines the number of steps (acceleration/deceleration/stop)
in one cycle. Each operation, either in the forward or reverse
direction, constitutes one step. If set to ‘2,’ one forward step and
one reverse step constitute one cycle.
