Danfoss VLT Midi Drive FC-280P4K0 [88/136] Notice

Danfoss VLT Midi Drive FC-280P11K [88/136] Notice
14-41 AEO Minimum Magnetisation
Range: Function:
66 %* [40 -
75 %]
Enter the minimum allowable magnetization
for AEO. Selection of a low value reduces
energy loss in the motor, but can also
reduce resistance to sudden load changes.
14-44 d-axis current optimization for IPM
Range: Function:
100
%*
[0 -
200 %]
This parameter is available only when
parameter 1-10 Motor Construction is set to [2]
PM, salient IPM, non-Sat.
Normally, VVC
+
PM control automatically
optimizes d-axis demagnetizing current based on
d-axis and q-axis settings. When
parameter 1-10 Motor Construction is set to [2]
PM, salient IPM, non-Sat, use this parameter to
compensate the saturation eect at high load.
Usually, decreasing this value improves the
eciency. However, 0% means no optimization
and the d-axis current is 0 (not recommended).
14-51 DC-Link Voltage Compensation
Option: Function:
[0] O Disables DC-link compensation.
[1] * On Enables DC-link compensation.
14-52 Fan Control
This feature is only available in frequency converters 11–75 kW
(14.8–100.6 hp).
Option: Function:
[5] Constant-on mode
[6] Constant-o mode
[7] On-when-Inverter-is-on-else-o
Mode
[8] * Variable-speed mode
14-55 Output Filter
Option: Function:
NOTICE
This parameter cannot be changed
while the motor is running.
Select the type of output lter connected.
[0] * No Filter
[1] Sine-Wave Filter
14-61 Function at Inverter Overload
When the frequency converter issues a frequency converter
overload warning, select whether to continue and trip the
frequency converter, or derate the output current.
Option: Function:
[0] * Trip
[1] Derate
14-63 Min Switch Frequency
Option: Function:
Set the minimum switch frequency allowed by
the output lter.
[2] * 2.0 kHz
[3] 3.0 kHz
[4] 4.0 kHz
[5] 5.0 kHz
[6] 6.0 kHz
[7] 8.0 kHz
[8] 10.0 kHz
[9] 12.0 kHz
[10] 16.0 kHz
14-64 Dead Time Compensation Zero Current Level
Option: Function:
[0] * Disabled
[1] Enabled If using a long motor cable, select this option to
minimize the motor torque ripple.
14-65 Speed Derate Dead Time Compensation
Range: Function:
Size
related*
[ 20 -
1000 Hz]
Deadtime compensation level is reduced
linearly versus output frequency from
the maximum level set in
parameter 14-07 Dead Time Compen-
sation Level to a minimum level set in
this parameter.
14-89 Option Detection
Selects the behavior when an option change is detected. This
parameter returns to [0] Protect Option Cong. after an option
change.
Option: Function:
[0] * Protect Option Cong. Freezes the current settings and
prevents unwanted changes when
missing or defective options are
detected.
[1] Enable Option
Change
Settings can be changed when the
system conguration is being
modied.
