4.6 Fan control

Fan control F6

The F6 has one or more fans depending on the device size and the cooling version
(air or water cooling or flat rear). Whether a fan is included and whether it is imple-
mented as an individual fan or a fan group can only be determined from the instal-
lation manual for the respective power unit.
A distinction is made between the interior fans, which are controlled by the internal
temperatures(ru26
heat sink fans, which are dependent on the heat sink temperature.
Some devices contain fans that adjust their speed depending on the temperature
and the individual fans in a group are sometimes switched on sequentially. Other
inverters have only the on/off state of the fans.
The switch-on temperature can be changed by parameters
is26 cooling fan HS level
is27 cooling fan ID level
Value Meaning
The fan / fan group is always running at full speed. The start process (sequential
-1: on
activation or start ramp) is pass through.
0: LT Value Fan is activated with default setting (power unit-dependent)
0.1...°C
Activation threshold in °C. The upper limit depends on the respective power unit.
For inverters that contain variable-speed fans, the temperature at which the maxi-
mum fan speed is reached can also be parameterized:
is28 HS fan full speed temp
is29 ID fan full speed temp
Value Meaning
0: LT Value Fan reaches maximum speed with default setting (power unit-dependent)
0.1...°C
Maximum speed level in °C. The upper limit depends on the respective power unit.
