3.11.6 14-5* Environment
These parameters help the frequency converter to operate
under special environmental conditions.
96
Function:
low speed. Selection of a low value reduces
energy loss in the motor, but also reduces
load capability.
Function:
[40 - 75 Enter the minimum allowable magnet-
isation for AEO. Selection of a low
value reduces energy loss in the
motor, but can also reduce resistance
to sudden load changes.
Function:
Automatic Energy Optimisation (AEO) is to
be active.
Function:
[0.40 - The Cos(phi) setpoint is automatically
set for optimum AEO performance
during AMA. This parameter should
normally not be altered. However in
some situations it may be necessary to
enter a new value to fine-tune.

Function:
isolated mains source (IT mains).
If a filter is used, select Off [0] during charging to
prevent a high leakage current making the RCD
switch.
In this mode, the internal RFI filter capacitors between
chassis and the mains RFI filter circuit are cut-out to
reduce the ground capacity currents.
complies with EMC standards.
Function:
Select the minimum speed of the main fan.
Select [0] Auto to run the fan only when the
internal temperature of the frequency converter
is in the range +35 °C to approximately +55 °C.
The fan will run at low speed at +35 °C and at
full speed at approximately +55 °C.
Function:
Select which reaction the frequency converter
should take in case a fan fault is detected.
Function:
Select the type of output filter connected. This
parameter cannot be adjusted while motor is
running.
