Parameter Descriptions
14-42 Minimum AEO Frequency
Range: Function:
NOTICE
Size [0 - 255 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.
14-44 d-axis Reference Gain
Range: Function:
100 % [0 - 200 %] Adjustment parameter for the d-axis
*
current. 100% indicates maximum
torque per ampere value based on
motor parameters. Increasing the
maximum torque can improve the
power factor of the machine which
may increase the current
consumption.
The adjustment parameter allows
to:
Adjust minimum current
consumption, allowing for
tolerances in the motor parameters.
Obtain the optimal balance
between current consumption and
power factor of the machine at a
given point of operation.

3.14.5 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).

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
