Parameter Descriptions
14-41 AEO Minimum Magnetisation
Range: Function:
66 % [40 - Enter the minimum allowable magnetization
*
75 %] 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 - This parameter is available only when
% 200 %] parameter 1-10 Motor Construction is set to [2]
*
PM, salient IPM, non-Sat.
+
Normally, VVC
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 effect at high load.
Usually, decreasing this value improves the
efficiency. However, 0% means no optimization
and the d-axis current is 0 (not recommended).
14-51 DC-Link Voltage Compensation
Option: Function:
[0] Off Disable DC-link compensation.
[1] On Enable DC-link compensation.
*
14-52 Fan Control
Option:
[5] Constant-on mode
[6] Constant-off mode
[7] On-when-Inverter-is-on-else-off 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 filter 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:
[0] Trip
*
[1] Derate

14-63 Min Switch Frequency
Option: Function:
Set the minimum switch frequency allowed by
the output filter.
[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 [ 20 - Deadtime compensation level is reduced
related 1000 Hz] 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
Select the behavior when an option change is detected. This
parameter returns to [0] Protect Option Config. after an option
change.
Option: Function:
[0] Protect Option Config. Freeze the current settings and
*
prevents unwanted changes when
missing or defective options are
detected.
[1] Enable Option Settings can be changed when the
Change system configuration is being
modified.
14-90 Fault Level
Use this parameter to customize fault levels. Use the 8
to control the fault level of alarm 13, Overcurrent.
Option: Function:
[3] Trip Lock Alarm is set to trip-lock.
*
[4] Trip w. Alarm is configured into trip alarm, which
delayed reset can be reset after a delay time. For
example, if alarm 13, Overcurrent is
configured to this option, it can be reset 3
minutes after the alarm.
