7.11.11 Timing Function
Function Code Parameter Name Setting Range Default
F8-42 Timing function 0: Disabled
1: Enabled
0
F8-43 Timing running time setting channel 0: Set by F8-44
1: AI1
2: AI2
3: AI3
(100% of analog input corresponds to the value of F8-44)
0
F8-44 Timing running time 0.0 to 6500.0 min 0.0

When the set timing running time is reached, the AC drive stops automatically and the digital output terminal set for the function
30 becomes on.
The AC drive starts timing from 0 again for each startup. You can view the remaining timing running time in U0-20.

Function Code Parameter Name Setting Range Default
F8-45 AI1 input voltage lower limit 0.00 V to F8-46 3.10 V
F8-46 AI1 input voltage upper limit F8-45 to 10.00 V 6.80 V
These two function parameters indicate whether the AI1 input voltage is in the setting range. If the AI1 input is larger than F8-46 or
smaller than F8-45, the digital output terminal set for the function 31 becomes on.
7.11.13 Module Temperature
Function Code Parameter Name Setting Range Default
F8-47 Module temperature threshold 0°C to 100°C 75°C
This function parameter sets the module temperature threshold. When the heatsink temperature reaches the value set in F8-47, the
digital output terminal set for the function 35 becomes on.
7.11.14 Cooling Fan
Function Code Parameter Name Setting Range Default
F8-48 Cooling fan working mode 0: Working during drive running
1: Working continuously
0
This function parameter sets the working mode of the cooling fan.
ƕ F8-48 = 0: Working during running
The fan works during drive running. When the drive stops, the fan works if the heatsink temperature is above 40°C and stops
if the heatsink temperature is below 40°C.
ƕ F8-48 = 1: Working continuously
The fan keeps working after power-on.
