stop time will recount and the inverter will display stop error signal of HIbFt when the stop time ends.
Note: When user does not want the inverter to be restricted by the maximum flow, set 23-76=0 (disable) to
disable the function of high flow limit.

High Flow Setting
Range
【0】Disable

When 23-76=0, High flow warning or error is disabled.
When 23-76=1, High flow warning is enabled. High flow error is disabled.
When 23-76=2, High flow warning or error is enabled. Refer to the instruction of Fig. 4.4.113.
23-51 Minimum Flow Value of Feedback
Range
【0.01~99.00】%
It is convenient for user to limit the minimum flow value depending on the different situations. When flow
feedback value is lower than the minimum flow value, the inverter will display warning signal and then
stops.
23- 52 Minimum Flow Warning Time of Feedback
Range
【0~255】Sec
When flow feedback is lower than the minimum flow limit, warning time of low flow starts to count. If the
flow feedback is higher than the minimum flow limit during counting time, the warning time will recount and
the inverter will display the warning signal of LFPb when the warning time ends.
T1 < (23-49): Recounting after T1.
T2 = (23-49): Keypad flashes and displays HFPb
T3 = (23-50): Keypad flashes and displays HIPbt
