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
Option: Function:
[0] Off Select [0] Off only when the frequency converter is
supplied from an isolated mains source, that is, IT
mains. In this mode, the internal RFI capacities (filter
capacitors) between chassis and the mains RFI filter
circuit is cut off to avoid damage to the DC link and
to reduce the ground capacity currents (according to
IEC 61800-3).
[1] On Select [1] On to ensure that the frequency converter
*
complies with EMC standards.
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.
[0] Off Disables DC-link compensation.
[1] On Enables DC-link compensation.
14-52 Fan Control
Option:

VLT
Function:
NOTICE
This parameter is not active when
parameter 1-10 Motor Construction is set
to [1] PM, non-salient SPM.
The Cos(phi) setpoint is automatically set to
optimum AEO performance during AMA. Under
normal circumstances, do NOT alter this
parameter. However, in some situations it may
be necessary to enter a new value to fine-tune.
Function:
Select the minimum speed of the main fan.

14-56 Capacitance Output Filter
Enter the capacitance of the output filter. Find the value on the
filter label. For the compensation function of the LC filter in the
star connection, enter the per phase equivalent capacitance of
the filter (3 times the capacitance between 2 phases in the delta
connection).

Function:
Select [0] Auto to run the fan only when the
internal temperature of the frequency
converter is in the range 35 °C (95 °F) to
approximately 55 °C (131 °F). The fan runs at
low speed at 35 °C (95 °F) and at full speed
at approximately 55 °C (131 °F).
Function:
Select the frequency converter action if a fan
fault is detected.
