Basic setup
Operating modes
There are 12 operating modes available (mode 3 reserved)
See section 8.1.3
CT ratio
Ratio of an external CT, such as 600:5 etc. - configurable
CT position
Either on the grid or load side, must match the current CT
position
Power transformer
ratio
Ratio of an external transformer (configurable)
Compensation
mode
Intelligent mode, sequential mode or “All” mode
Hybrid parameter
Reserved
Slave module
quantity
Quantity of slave devices (configurable)
Total capacity
Total capacity of the system: corresponds to the sum of the
rated currents of the individual modules in parallel operation
Factory setting (not configurable)
Power On mode
Is used for setting the power on mode of the AHF.
“Auto” mode: The AHF automatically compensates the load
harmonics current.
“Manual” mode starts the compensation only once the power
on command has been received (Power ON).
Controller param-
eter I
Parameter of the internal control circuit. The larger the
parameter, the greater the stability. The power also increases
(not configurable)
Comp. rate
Set the harmonic compensation component;
1.0 shows 100%, etc.
Target power
factor
In the “Harmonic and power factor correction” mode, you can
set the PF value on the grid side. The AHF adjusts the intensity
and phase of the reactive current in accordance with its own
load share so that the grid PF reaches the target value.
Voltage
Factory setting of the AHF voltage level
(not configurable)
Config. of induc-
tance current
Used for selection of the inductive or capacitive
reactive power (not configurable)
Network configu-
ration
Network system of the AHF (3-phase and 3-conductor or
3-phase and 4-conductor) factory setting (not configurable)
External passive
filter
Reserved
CT secondary
connection
Selection of the connection on the CT secondary side (a series
connection is recommended)
Variable 1
Check the internal DSP variable;
(not configurable)
Variable 2
Check the internal DSP variable;
(not configurable)
