14-30 Current Lim Cont, Proportional Gain
Range:
Function:
100 %
*
[0 - 500 %] Enter the proportional gain value for the
current limit controller. Selection of a high
value makes the controller react faster. Too
high a setting leads to controller instability.
14-31 Current Lim Contr, Integration Time
Range:
Function:
0.020 s
*
[0.002 - 2.000
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:
1.0 ms
*
[1.0 - 100.0 ms]
14-35 Stall Protection
Option:
Function:
Select Enable [1] to enable the stall protection in
field-weakening in flux mode. Select Disable [0] if
you desire to disable it. This might cause the motor
is active in flux
mode only.

3.15.5 14-4* Energy Optimizing
Parameters for adjusting the energy optimization level in
both Variable Torque (VT) and Automatic Energy Optimi-
zation (AEO) mode in
14-40 VT Level
Range:
Function:
66 %
*
[40 - 90
%]
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.
This parameter cannot be adjusted while the
motor is running.
14-41 AEO Minimum Magnetization
Range:
Function:
Application
dependent
*
[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.
14-42 Minimum AEO Frequency
Range:
Function:
10 Hz
*
[5 - 40 Hz] Enter the minimum frequency at which the
Automatic Energy Optimization (AEO) is to
be active.
14-43 Motor Cos-Phi
Range:
Function:
Application
dependent
*
[0.40 -
0.95 ]
The Cos(phi) setpoint is automatically
set for optimum AEO performance.
This parameter should normally not be
altered. However, in some situations it
may be necessary to enter a new value
to fine tune.
3.15.6 14-5* Environment
These parameters help the adjustable frequency drive to
operate under special environmental conditions.
14-50 RFI 1
This parameter is only available for FC 302. It is not relevant to the
FC 301 due to the different design and shorter motor cables.
Option:
Function:

Select
Off
[0] only if the adjustable frequency drive is fed
by an isolated line power source (IT line power).
In this mode, the internal RFI filter capacitors between
chassis and the line power RFI filter circuit are cut-out to
reduce the ground capacity currents.

14-51 DC Link Compensation
Option:
Function:
[0]
Off
Disables DC Link Compensation.

*
On
Enables DC Link Compensation.
14-52 Fan Control

[0] to run fan only when internal temperature in
adjustable frequency drive is in the range of 95°F [35°C] to approx-
imately 131°F [55°C].
Fan runs at low speed below 95°F [35°C], and at full speed at
approximately 131°F [55°C].
