Code Description
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
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.
AP2-31 PC End Mode
Determines the inverter operation after pump clean operation.
Setting Function
0 Stop This stops the inverter after pump cleaning.
1 Start The inverter operates based on the inverter’s
command status after the pump cleaning. (If a
terminal command is received, the inverter
performs the operation it was performing before
the pump clean operation.)
AP2-29 Repeat Num Mon Displays the number of the current pump cleaning cycle.
AP2-30 Repeat Num Set
Sets the number of cycles for one pump clean operation set at
AP2-21–AP2-28.
AP2-32 PC Limit Time
AP2-33 PC Limit Num
Frequent pump clean operations may indicate a serious system
problem. To warn the users of potential system problems, an error
(CleanRPTErr) occurs if the number of pump clean operation
