Description
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 a pump clean.
AP2-22 PumpClean AccT
AP2-23 PumpClean
DecT
Sets the Acc/Dec times for pump clean operations.
AP2-24 Fwd Steady Time Sets the time to maintain forward and reverse operations.
