14-31 Current Lim Ctrl, Integration Time
Range: Function:
0.020 s* [0.002 - 2 s] Controls the current limit control
integration time. Setting it to a lower
value makes it react faster. A setting too
low leads to control instability.
14-32 Current Lim Ctrl, Filter Time
Range: Function:
5 ms* [1 - 100 ms] Sets a time constant for the current limit
controller low-pass lter.
14-40 VT Level
Range: Function:
66 %
*
[40 -
90 %]
NOTICE
This parameter cannot be adjusted while
the motor is running.
NOTICE
This parameter is not active when
parameter 1-10 Motor Construction is set to
options that enable PM motor mode.
Enter the level of motor magnetization at low
speed. Selection of a low value reduces energy
loss in the motor, but also reduces load
capability.
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 eect at high load.
Usually, decreasing this value improves the
eciency. 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.
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 If using a long motor cable, select this option to
minimize the motor torque ripple.
