3.10.4 14-3* Current Limit Control
Parameters for conguring the current limit controller,
which is activated when the motor current exceeds the
preset current limits (see parameter 4-18 Current Limit).
These parameters are used to reduce torque as quickly as
possible without losing control of the motor.
14-30 Current Lim Ctrl, Proportional Gain
Range: Function:
100 %
*
[0 - 500 %] Enter the proportional gain value for the
current limit controller. A higher value
makes the controller react faster. Excessive
value setting leads to controller instability.
14-31 Current Lim Ctrl, Integration Time
Range: Function:
0.020 s
*
[0.002 - 2 s] Control 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] Set a time constant for the current limit
controller low-pass lter.
3.10.5 14-4* Energy Optimization
Parameters for adjusting the energy optimization level in
both variable torque (VT) and automatic energy optimi-
zation (AEO) mode.
Automatic energy optimization is only active if
parameter 1-03 Torque Characteristics is set for [3] Auto
Energy Optim.
14-40 VT Level
Range: Function:
90 %
*
[40 -
90 %]
NOTICE
This parameter cannot be adjusted
while the motor is running.
Enter the level of motor magnetization at low
speed. Low values reduce energy loss in the
motor, but also reduce load capability.
14-41 AEO Minimum Magnetisation
Range: Function:
66 %
*
[40 - 75 %] Enter the minimum allowable magnetization
for AEO. Low values reduce energy loss in
the motor, but also reduce resistance to
sudden load changes.
14-44 d-axis current optimization for IPM
Range: Function:
100 %
*
[0 - 200 %] Parameter group for conguring special
frequency converter functions.
3.10.6 14-5* Environment
These parameters help the frequency converter to operate
under special environmental conditions.
14-50 RFI Filter
This parameter is only valid for frequency converters of the
following enclosure sizes:
•
IP20, 3x200–240 V, enclosure sizes H6–H8
•
IP20, 3x380–480 V, enclosure sizes H6–H8
•
IP54, 3x380–480 V, enclosure sizes I6–I8
•
IP20, 3x525–600 V, enclosure sizes H6–H10
Option: Function:
[0] O Select [0] O only if the frequency converter is fed by
an isolated mains source (IT mains).
In this mode, the internal RFI lter capacitors between
chassis and the mains RFI lter circuit are cut out to
reduce the ground capacity currents.
[1]
*
On Select [1] On to ensure that the frequency converter
complies with EMC standards.
14-51 DC-Link Voltage Compensation
Option: Function:
[0] O The overmodulation for output voltage is o to avoid
torque ripple on the motor shaft.
[1]
*
On Enables the overmodulation for output voltage to
obtain an output voltage up to 15% greater than the
mains voltage.
14-52 Fan Control
This parameter is only valid for frequency converters of the
following enclosure sizes:
•
IP20, 3x200–240 V, enclosure sizes H6–H8
•
IP20, 3x380–480 V, enclosure sizes H6–H8
•
IP54, 3x380–480 V, enclosure sizes I6–I8
•
IP20, 3x525–600 V, enclosure sizes H6–H10
Option: Function:
[0]
