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 internal temperature PU / ru77 internal temperature CB) and the
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 / is27.
is26
cooling fan HS level
0x351A
is27
cooling fan ID level
0x351B
Value
Meaning
-1: on
The fan / fan group is always running at full speed. The start process (sequential
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
0x351C
is29
ID fan full speed temp
0x351D
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.
