These two parameters are used to set the limi
ts of the input voltage to provide
protection on the AC drive. When the AI1 input is larger than the
value of P2.43 or smaller than the value of P2.44, the
corresponding DO becomes ON, indicating that AI1 input exceeds
the limit.
P2.45
Module temperature
threshold
Setting Range：0℃～
100℃
75℃
When the heatsink temperature of the AC drive reaches the value
of this parameter, the corresponding DO becomes ON, indicating
that the module temperature reaches the threshold.
P2.46
Cooling fan control
Setting Range：0～1 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
