Parameter Description
14-42 Minimum AEO Frequency
Range: Function:
10 Hz [5 - 40 Hz] Enter the minimum frequency at which the
*
Automatic Energy Optimization (AEO) is to
be active.
NOTICE!
This parameter is not active when 1-10 Motor Construction
is set to [1] PM, non-salient SPM.
14-43 Motor Cos-Phi
Range: Function:
Size [0.40 - The cos-phi setpoint is automatically set
related 0.95 ] 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.
NOTICE!
This parameter is not active when 1-10 Motor Construction
is set to [1] PM, non-salient SPM.
3.13.5 14-5* Environment
These parameters help the adjustable frequency drive to
operate under special environmental conditions.
14-50 RFI 1
Option: Function:
[0] Off
[1] On Select [1] On to ensure the adjustable frequency drive
complies with EMC standards.
Select [0] Off only when the adjustable frequency drive
is supplied from an isolated line power source, i.e., IT
line power. In this mode, the internal RFI capacities
(filter capacitors) between chassis and the Line Power
RFI Filter Circuit are cut off to avoid damage to the
intermediate circuit and to reduce the ground capacity
currents (according to IEC 61800-3).
14-51 DC Link Compensation
Option: Function:
The rectified AC/DC voltage at the adjustable frequency
drive'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 at DC
link. In general, DC link compensation is recommended
for most applications, but care must be taken when
operating in field weakening as it can generate speed

oscillations at the motor shaft. In field weakening, it is
recommended to turn DC link compensation off.
Function:
Select the minimum speed of the main fan.
Select [0] Auto to run the fan only when the
internal temperature of the adjustable
frequency drive is in the range 95° F [+35°C]
to approximately 131° F [+55°C]. The fan will
run at low speed at 95° F [+35°C] and at full
speed at approximately 131° F [+55°C].

Function:
Select which action the adjustable frequency drive
should take in case a fan fault is detected.
Function:
Select the type of output filter connected.
Filter
If a Danfoss sine-wave filter is connected to the
Filter output, this option secures that the switching
Fixed frequency is fixed above the design frequency of
the filter (to be set in 14-01 Switching Frequency)
in the specific power size. This prevents the filter
from being noisy, overheated and damaged.
NOTICE!
The switching frequency will still be
automatically controlled by the TAS feature
depending on the temperature but limited
to always be above the critical level for the
Danfoss filter.
