operation by turning on the terminal.
Performs a pump clean operation when a
pump consumes more power than it is
supposed to consume in a normal
operation.
Performs a pump clean operation when a
pump consumes more current than it is
supposed to consume in a normal
operation.
Sets the pump clean start mode.
Pump clean is performed only by the
function set at AP2-20.
Pump clean is performed each time the
inverter starts operating.
Pump clean is performed each time the
inverter stops operating.
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.
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.
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.
Sets the time to maintain forward and reverse operations.
