Parameter Descriptions
14-52 Fan Control
Select minimum speed of the main fan.
Option: Function:
[0] 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 approximately 55 °C (131 °F).
[1] 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).
[2] 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).
[3] On 100% The fan always runs at 100% speed.
14-53 Fan Monitor
Option: Function:
Select the frequency converter action if a fan
fault is detected.

14-55 Output Filter
Option: Function:
NOTICE
This parameter cannot be adjusted while the
motor is running.
NOTICE
Reset the frequency converter after selecting
[2] Sine-Wave Filter Fixed.
CAUTION
OVERHEATING OF FREQUENCY
CONVERTER
When using sine-wave filters, there is a risk
of overheating of the frequency converter,
which can result in personal injury and
equipment damage.
Always set parameter 14-55 Output Filter to
[2] Sine-wave fixed when using a sine-wave
filter.
Select the type of output filter connected.
[0] No This is the default setting and should be used with
Filter dU/dt filters or high frequency common mode (HF-
*
CM) filters.
[1] Sine- This setting is only for backwards compatibility. It
Wave enables operation with flux control principle when

14-55 Output Filter
Option:
14-56 Capacitance Output Filter
Compensation function of the LC filter requires the per phase
equivalent star-connected capacitance of the filter (3 times the
capacity between 2 phases when capacitance is delta
connection).

Function:
parameter 14-56 Capacitance Output Filter and
parameter 14-57 Inductance Output Filter are
programmed with the output filter capacitance and
inductance. It does not limit the range of the
switching frequency.
Function:
[0.1 - 6500.0 Set the capacitance of the output
uF] filter. The value can be found on the
filter label.
NOTICE
This is required for correct
compensation in flux mode
(parameter 1-01 Motor Control
Principle).
Function:
[0.001 - Set the inductance of the output filter.
65.000 mH] The value can be found on the filter
label.
NOTICE
This is required for correct compen-
sation in flux control principle
(parameter 1-01 Motor Control
Principle).
Function:
[1 - N/A] Set the actual number of power units.
