Parameter Descriptions
14-42 Minimum AEO Frequency
Range: Function:
NOTICE
Size [0 - 40 Hz]
related
*
This parameter is not active
when parameter 1-10 Motor
Construction is set to [1] PM
non-salient SPM.
Enter the minimum frequency at
which the automatic energy optimi-
zation (AEO) is to be active.
14-43 Motor Cosphi
Range: Function:
Size [0.40 - 0.95] The Cos(phi) setpoint is automat-
related ically set for optimum AEO

performance. This parameter should
normally not be altered. However,
in some situations it may be
necessary to enter a new value to
fine-tune.
4.13.5 14-5* Environment
NOTICE
Perform a power cycle after changing any of the
parameters in parameter group 14-5* Environment.
These parameters help the frequency converter to operate
under special environmental conditions.
14-50 RFI Filter
Turn the RFI filter on or off. The RFI filter ensures that the
frequency converter complies with EMC standards. Select [0] Off
only when the frequency converter is connected to an isolated
mains source (IT mains).
Option: Function:
[0] Off
[1] On

14-51 DC-Link Compensation
Option: Function:
The rectified AC-DC voltage in the
frequency converter's DC link is
associated with voltage ripples.
These ripples can increase in
magnitude with increased load.
These ripples are undesirable
because they can generate current
and torque ripples. A compensation
method is used to reduce these
voltage ripples in the DC link. In
general, DC-link compensation is
recommended for most

applications, but pay attention
when operating in field weakening
as it can generate speed oscillations
at the motor shaft. In field
weakening, turn off DC-link
compensation.
Off Disables DC-link compensation.
On Enables DC-link compensation.
Function:
Auto Select [0] Auto to run fan only
when internal temperature in
frequency converter is in range
35 °C (95 °F) to approximately
55 °C (131 °F).
Fan runs at low speed below 35 °C
(95 °F), and at full speed at approx-
imately 55 °C (131 °F).
On 50% The fan always runs at 50% speed
or above. The fan runs at 50%
speed at 35 °C (95 °F), and at full
speed at approximately 55 °C
(131 °F).
On 75% The fan always runs at 75% speed
or above. The fan runs at 75%
speed at 35 °C (95 °F), and at full
speed at approximately 55 °C
(131 °F).
On 100% The fan always runs at 100% speed.
Auto (Low This option is the same as [0] Auto,
temp env.) but with special considerations
around and below 0 °C (32 °F). In
option [0] Auto there is a risk that
the fan starts running at around
0 °C as the frequency converter
detects a sensor fault and thus
protects the frequency converter
while reporting warning 66, Heat
sink Temperature Low. Option [4]
Auto (Low temp env.) can be used in
very cold environments and
prevents the negative effects of this
further cooling and avoids warning
66, Heat sink Temperature Low.
