Function Code Parameter Name Setting Range Default
F8-48 Cooling fan control
0: Fan working during running
1: Fan working continuously
0
It is used to set the working mode of the cooling fan. If this parameter is set to 0, the fan
works when the AC drive is in running state. When the AC drive 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 working after power-on.
Function Code Parameter Name Setting Range Default
F8-49 Wakeup frequency
Dormant frequency (F8-51) to
maximum frequency (F0-10)
0.00 Hz
F8-50 Wakeup delay time 0.0–6500.0s 0.0s
F8-51 Dormant frequency 0.00 Hz to wakeup frequency (F8-49) 0.00 Hz
F8-52 Dormant delay time 0.0–6500.0s 0.0s
These parameters are used to implement the dormant and wakeup functions in the water
supply application.
When the AC drive is in running state, the AC drive enters the dormant state and stops
automatically after the dormant delay time (F8-52) if the set frequency is lower than or equal
to the dormant frequency (F8-51).
When the AC drive is in dormant state and the current running command is effective, the AC
drives starts up after the wakeup delay time (F8-50) if the set frequency is higher than or
equal to the wakeup frequency (F8-49).
Generally, set the wakeup frequency 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 FA-28. In this case, select PID
operation enabled in the stop state (FA-28 = 1).
Function Code Parameter Name Setting Range Default
F8-53 Current running time reached 0.0–6500.0 min 0.0 min
If the current running time reaches the value set in this parameter, the corresponding DO
becomes ON, indicating that the current running time is reached.
Function Code Parameter Name Setting Range Default
F8-54 Output power correction coefcient 0.00%–200 .0% 100.0%
When the output power (U0-05) is not equal to the required value, you can perform linear
correction on output power by using this parameter.
