14-40 VT Level
Range:
Function:
66 %
*
[40 - 90 %] Enter the level of motor magnetisation at
low speed. Selection of a low value reduces
energy loss in the motor, but also reduces
load capability.
NOTE
This parameter cannot be adjusted while the motor is
running.
NOTE
This parameter is not active when
is set to
[1] PM non salient SPM
.
14-41 AEO Minimum Magnetisation
Range:
Function:
Size related
*
[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.
NOTE
This parameter is not active when
is set to
[1] PM non salient SPM
.
14-42 Minimum AEO Frequency
Range:
Function:
10 Hz
*
[5 - 40 Hz] Enter the minimum frequency at which the
Automatic Energy Optimisation (AEO) is to
be active.
NOTE
This parameter is not active when
is set to
[1] PM non salient SPM
.
14-43 Motor Cosphi
Range:
Function:
Size

*
[0.40 -
0.95 ]
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.
NOTE
This parameter is not active when
is set to [1] PM non salient SPM.
3.11.6 14-5* Environment
These parameters help the frequency converter to operate
under special environmental conditions.
14-50 RFI Filter
This parameter is only available for . It is not relevant to due to
different design and shorter motor cables.
Option: Function:
[0]
Off Select
[0] Off
if the frequency converter is fed by an
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.
[1]
*
On Select
[1] On
to ensure that the frequency converter
complies with EMC standards.

14-52 Fan Control
Option:
Function:
Select the minimum speed of the main fan.
[0]
*
Auto
Select
[0] Auto
to run the fan only when the
internal temperature of the frequency converter
is in the range +35
°
C to approxi55

C.
The fan will run at low speed at +35
°
C and at
full speed at approxi55
°
C.

Option:
Function:
Select which reaction the frequency converter
should take in case a fan fault is detected.

Option:
Function:
Select the type of output filter connected. This
parameter cannot be adjusted while motor is
