AP2-25 Fwd SteadyFreq
AP2-27 Rev SteadyFreq
Sets the forward and reverse operation frequencies.
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.
Determines the inverter operation after pump clean operation.
This stops the inverter after pump cleaning.
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.)
Displays the number of the current pump cleaning cycle.
Sets the number of cycles for one pump clean operation set
at AP2-21–AP2-28.

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 exceeds the number set at AP2-33
within the time period set at AP2-32.
• When the run prevent feature is active and an operation in the prevented direction is
required to perform a pump clean operation, the inverter operates at the 0 speed for the
time set at AP2-24 and AP2-26 (Steady Time).
• To stop the pump clean operation, press the OFF key on the keypad or turn it off at the
terminal input.
• If the pump clean operation is configured for terminal input and it is turned on, and if ADV-10
(PowerOn Resume) is set to ‗Yes‘, a pump clean operation is performed when the inverter
is turned on.
• When performing a pump clean operation via terminal input,
- if the terminal input is turned off instantly after it is turned on (the operation is
triggered), 1 pump clean cycle is operated.
