b2-23
Cooling fan control
Default
0
Setting
Range
0
Fan working during running
1
Fan working during power on
It is used to set the working mode of the cooling fan. If this parameter is set to 0, the fan works when the frequency
inverter is in running state. When the frequency inverter stops, the cooling fan works if the heatsink temperature is
higher than 40°C, and stops working if the heatsink temperature is lower than 40°C.
If this parameter is set to 1, the cooling fan keeps always working after power-on.
b2-24
Dormant frequency
Default
0.00Hz
Setting Range
0.00Hz ~wakeup frequency (b2-26)
b2-25
Dormant delay time
Default
0.0s
Setting Range
0.0s~6000.0s
b2-26
Wakeup frequency
Default
0.00Hz
Setting Range
Dormant frequency (b2-24)~ maximum frequency (b0-13)
b2-27
Wakeup delay time
Default
0.0s
Setting Range
0.0s~6000.0s
These parameters are used to implement the dormant and wakeup functions in the water supply application.
When the frequency inverter is in running state, the frequency inverter enters the dormant state and stops
automatically after the dormant delay time (b2-25) if the set frequency is lower than or equal to the dormant
frequency (b2-24).
When the frequency inverter is in dormant state and the present running command is effective, the frequency inverter
start up after the wakeup delay time (b2-27) if the set frequency is higher than or equal to the wakeup frequency
(b2-26).
Generally, set the wakeup frequency should be equal to or higher than the dormant frequency. If the wakeup
frequency and dormant frequency are set to 0, the dormant and wakeup functions are disabled.
When the dormant function is enabled, if the frequency source is PID, whether PID operation is performed in the
dormant state is determined by C0-27. In this case, select PID operation enabled in the stop state (C0-27 = 1).

b2-30
Set timing duration
Default
0.0min
Setting Range
0.0min~6500.0 min
These parameters are used to implement the frequency inverter timing function.
If b2-28 is set to 1, the frequency inverter starts to time at startup. When the preset timing duration reached, the
frequency inverter stops automatically, and meanwhile the corresponding DO outputs ON signal.
The frequency inverter starts timing from 0.0min each time it starts up and the remaining timing duration can be
checked by U0-20.
The timing duration is set by b2-29 and b2-30, in unit of minute.
b2-31
The present running time reached
Default
0.0min
Setting Range
0.0min~6500.0 min
If the present running time reaches the value set in this parameter, the corresponding DO outputs ON signal,
indicating that present running time is reached.
