1. General
This application is not kept backwards compatible. See chapter Compatibility issues before you
update the application. The Grid Converter application is used to make AC grids with a possibility to
operate in parallel with other power sources. The Grid Converter application has 3 different operation
modes:
- Standard AFE mode.
- Island mode.
- Micro Grid mode.
1.1 AFE Control
AFE function keeps constant DC voltage. AFE mode transfers power between DC and AC. AFE
cannot create grid by itself, it needs to be connected to existing grid.

1.2 Island (Static Power Supply)
Island mode generates constant voltage and frequency. In island mode DC Voltage is not controlled.
Island mode cannot operate in parallel with other power sources in AC side, because the drive will
not balance reactive or active power with other power sources.
DC voltage level needs to be considered to have correct voltage on AC side in different load
situations, considering voltage losses in LCL filter and in transformer.

1.3 Micro Grid
Micro Grid mode controls the grid voltage and frequency. It functions like an ordinary generator.
Micro Grid mode does not control DC Voltage.
With the help of voltage droop and frequency droop, more than one Micro Grid and/or Generators
can work together.

1.4 Shaft Generator
The shaft generator is a system where the generator is connected to the main engine shaft that also
runs the main propulsion. The disadvantage is that the main engine must run at nominal speed even
if full power to the propeller is not necessary.
With the shaft generator system power goes through the drives. One converts power from the
generator to DC link, and the other makes a ship grid with constant 50 Hz or 60 Hz, thus there is no
direct connection to the generator. The main engine can run at a more efficient speed without
changing grid frequency.
One drive operates as an AFE on the generator side and the other operates on Island mode or Micro
Grid mode on the grid side.
- The start command to generator side drive.
- Both drives can make DC charging if powered by +24 Vdc.
- When DC is at an 80% of nominal, the generator side and the grid side breakers close.
- The generator side AFE is started to boost DC first.
- The grid side Grid Converter is started and will synchronise to grid.
- The drives take power from the bypass, and the PMS opens the SG contactor.
- You can decrease the speed of the main diesel engine to be more economical.
NOTE! If it is necessary to have these systems in parallel, the system bus communication is
reserved for parallel Micro Grid units on the grid side. The control must be arranged separately for
each drive.

1.6 Compatibility issues in parameters between versions
Update Note 1: This application parameters are not kept backwards compatible if new features or
improvements would be difficult to implement by doing so. Read this change note and chapter
“Compatibility issues in parameters between versions” from manual before updating the application.
Update Note 2: It’s recommended to use compare function for parameter changes when updating
application, especially in cases when version number change is considerably high.
Application is constantly developed; this includes changing parameter default values, and if
parameters are directly downloaded to drive improved default values may be lost.
Update Note 3: If OPT-D7 PI voltage control is needed in uGrid mode, do not use versions V082 or
V083.
V092
• Major Compatibility Issue: P2.1.7 System Nom. DC is initialized to unit nominal DC value.
▪ 500 Vac unit: 675 Vdc
▪ 690 Vac unit: 931 Vdc
o When the transformer ratio was other than 1:1: MCB closing limit and DC-Link Voltage
reference values were based on grid voltage after transformer. This was causing reference
handling problems when given AC values were in range of different voltage class unit.
o DC Voltage Reference in AFE mode is based always to System Nom DC parameter.
V089
o Compatibility Issue: Voltage MotPot is adjusting now field weakening point voltage. Units have
been changed from [V] to [%]. This enables more accurate adjustment and adjustment rate.
V087
o Minor Compatibility Issue: FB Actual Speed signal changed to use Filtered DC-Link Voltage
signal (ID1108) instead of unfiltered DC Voltage signal.
V081
o Compatibility Issue: Parameters “PID Activation” and “FreqScaleMinAO” had same ID1807.
“FreqScaleMinAO” DI changed to ID1809.
o Major Compatibility Issue: Fieldbus State Machine
o See full details from latest manual.
o Not Used -> Basic, As in Fieldbus manual
o Standard –> NEW Standard, Application level state machine, this was Basic in earlier
versions than V081 i.e. as in Fieldbus manual.
o FB Status and FB Control word modified to be more suitable for AFE use, following
idea of ProfiDrive standard.
V080
o Minor compatibility issue: Monitoring and parameter values unified with other premium drive
applications.
V128
o Minor compatibility issue: P2.7.8 Control Options2 B1 is no longer available, this has been
replaced with P2.9.1.15 FaultWarnIndicat parameter.

2. Quick start and operation principles
NOTE! Before you start the commissioning, read the safety instructions in the user manual of your
product.
To use the Island, Micro Grid, or Shaft generator operation, you need a licence key. The AFE mode
is available without a licence.
This application requires an NXP3 control board VB761 or newer.
The control place (P3.1) of the Micro Grid drive is Keypad as a default.
The basic I/O configuration of the Grid Converter drive consists of OPT-A1, OPT-A2, and OPT-D7
option boards. The basic I/O configuration is described in Table 1.
OPT-D7 is required when the Grid Converter unit is needed to start with zero power to the grid. If
grid frequency is not monitored with OPT-D7, the unit may go generator side or directly to full power
because different reference frequency and grid frequency.
The Grid Converter is utilised by using AFE hardware with special software. An external LC(L)-filter
and charging circuit is needed. This unit is selected when low harmonics are required. The principle
connection of AFE drive has been described in Figure 5.
The external 24 Vdc is recommended for control board(s). It enables the setting of parameters even
when the power unit itself is not powered. This is important also when software updates are made.
Some default I/O configuration of the application can cause unexpected DO operation. When the
control board is powered, the drive can give information from the status of the system if, for example,
the drive I/O is used for an overall system monitoring.
The external 24 Vdc is required for the drives in cases where the start command starts the control
board-controlled precharging operation.
2.1 Quick start instructions
1. Connect the unit according to the Figure 5.
2. Power up the control unit with 24 Vdc.
3. Set the basic parameters (G2.1)
4. Check that the digital input parameters (G2.4.2) have been set according to the connections.
5. Change the control place according to the system requirements.
6. Charge the unit.
2.2 In case of parallel AFE:
1. Set P2.1.5 Parallel AFE to Yes. This will also set DC Drooping to 3.00% (Default).

2.3 Pre-Charging of DC
This AFE application has its own charging control, P2.5.1.13 DC Charge (24 Vdc required for control
board) and charging protection in case the external charging cannot get DC voltage to required level
within set time P2.9.1.6 Charge Max Time (provided that the DC Voltage reaches the under voltage
fault level).
The charging function is activated when P2.5.1.13 DC Charge is A.1 or higher. When the control
place is IO, Keypad or NCDrive, charging is started from the start command.
Charging is not started if:
- Drive is in fault state.
- P2.4.2.26 Enable CB Close is FALSE
- P2.4.2.8 Run Enable is FALSE
- P2.4.2.19 Quick Stop is FALSE
Charging is also stopped if above conditions occur during charging or if the start command is
removed.
For fieldbus control, charging is started with B0 of FB Control Word on the supporting FB profiles.
Charging is also stopped if B0 goes low. Also MCB is opened if already closed.
DC Charge (F80) is given if 85 % of DC Nominal is not reached within P2.9.1.6 Charge Max Time
and charging is stopped.
DC Charging is stopped when the drive receives feedback from P2.4.2.4 MCB Feedback.
NOTE! Use suitably sized DC Charging resistor. To select the correct size, check Pulse loadability
for time duration set in for Max Charge Time parameter.

2.4 Main circuit breaker control (MCB)
The Grid Converter application controls the circuit breaker of the system with the relay output RO2.
When the DC bus is charged, the MCB will be closed. The status of the MCB is monitored via a
digital input. The digital input used for monitoring is selected with parameter P2.3.1.3. Faults can be
set to open the MCB by selecting a response to a fault to be 3=Fault, DC OFF.
An external charging circuit is necessary to charge the DC bus but drive can control this circuit if 24
Vdc is provided for the control board.
Closing limit is 85% of the nominal DC Voltage.
Opening limit is 75% of the nominal DC Voltage.
Nominal DC Voltage = Grid Nom Voltage (P2.1.1) * 1.35.
Over Current (F1), Hardware IGBT (F31) and Software IGBT (F41) faults will open MCB immediately
to protect the drive.
NOTE! The MCB feedback is necessary for the correct operation of the Grid Converter application.
NOTE! Only the drive controls its own MCB. If additional interlocks or opening commands are
needed, these commands must go through the drive.
NOTE! UPS may be needed during short circuit situation to keep MCB closed if control voltage is
taken from the grid where the short circuit occurs.
NOTE! Missing feedback signal prevent drive going to ready state. MCB Feedback can be monitored
from Status Word B10.
NOTE! If feedback is not used there will be three second forced delay on internally generated MCB
feedback signal. MCB Feedback can be monitored from Status Word B10.

2.8 Operation principle: Droop Speed Control Mode
When the power demand increases, all generators on the grid allow frequency to droop. This will
balance the load between all the generators on the grid. Then the power management system gives
all generators a command to increase frequency so that the grid frequency is maintained at its
nominal value.
When the load is reducing on the grid, the frequency of the generators will increase, and the power
management system gives a command to decrease frequency.

2.9 Operation principle: Isochronous Speed Control Mode
In the isochronous speed control mode, the Micro Grid frequency reference is kept the same as the
grid frequency with help of OPT-D7. This will keep power at zero regardless of grid frequency. While
drive operates in drooping mode, the actual power is controlled by base current reference. This
reference needs to be controller by power management system (PMS) that will handle power sharing
between different machines on the grid.

2.10 Voltage compensation
Grid Converter system will have voltage losses. Depending on the system, the losses may be more
than 50 Vac when operating close to Grid Converter nominal currents with low power factor between
points U3 and U5. This voltage loss needs to be compensated so that the grid voltage stays at
nominal. This also sets requirements for the needed DC link voltage.

Figure 9. Voltage compensation
The normal operation voltage range in a land-based grid is usually between 80% and 115% of the
grid nominal voltage.
The voltage losses compensation is handled separately for Active power (kW) and Reactive power
(kVar), the latter being more significant. The Active power voltage losses are compensated with
Inductor Losses parameter (P2.2.6.6) and Reactive power voltage losses are compensated with
Inductor Size parameter (P2.2.6.5).
Uncompensated system may result in unnecessary reactive power circulation in a grid between the
different power sources and wrong grid voltage.
OPT-D7 can be used to compensate the voltage losses (closed loop voltage compensation) but it is
recommended to do an open loop voltage compensation tuning in case of OPT-D7 failure. When the
OPT-D7 measurements exceed the set limit values, the voltage compensation falls back to open
loop control.
Inductor Size and Losses affect
Grid Nom. Voltage: 400 Vac, Reactive Current: 30%, Active Current 50%, Inductor
Size: 15%, Inductor Losses: 15%, Voltage Correction: 0 Vac.
Reactive Increase: 400 Vac×30%×15%=18 Vac
Active Increase: 400 VacIncrease:or Losses: 15% 400 Vac×50%×15%×15%=4.5 Vac
Total increase: 18 Vac+4.5 Vac =22.5 Vac

2.11 OPT-D7
OPTD7 is an AC sinusoidal voltage measurement board. Using this board, the drive measures the
line voltage, the frequency and the voltage angle information.
The drive can compare this information with its output voltage angle when it runs. This feature can
be used to make synchronisations to a grid that is measured. For example, for line synchronisation
purposes you can use APFIFF44 LineSynch II Application. That will work as a smooth starter.
In Grid Converter application this can be used:
- To synchronise to existing external grid while the drive is running to enable bumpless transfer
from a generator operation to a shore powered operation in a ship.
- To control the grid voltage (Voltage losses compensation).
- To enable a zero power connection to an existing grid.
- To help in the commissioning of drive active power and reactive power voltage losses
compensation when the actual grid voltage is visible in NCDrive.
The OPT-D7 board is delivered with the transformer which is suitable for a voltage range up to 690
Vac. The transformer cannot be used with a pulse width modulated (PWM) voltage input.
It is possible to use a customised transformer when the input voltage to be measured is not within
the OPT-D7 transformer voltage range. The transformation ratio parameter can be adjusted
according to the transformer primary to secondary ratio. See details in the OPT-D7 user manual.
Synchronisation to the grid can be made without the OPT-D7 when the drive operates in the AFE or
the Micro Grid mode. This requires that the output terminals of the drive are connected to the
existing grid when the drive is in the STOP state. When a start command has been given in AFE or
Micro Grid mode, the drive will make standard AFE synchronisation. Depending on the operation
mode, the drive will start to keep constant DC voltage (AFE) or start to share power based on grid
frequency (Micro Grid). Using OPT-D7 for synchronisation will make the start of the drive smoother.
If the drive does not detect an existing line voltage or frequency in Micro Grid mode, the output
voltage is raised defined time (VoltageRiseTime). In the Island mode, the detection of the grid is not
made and the voltage is raised from zero in the set time (VoltageRiseTime).
NOTE: The OPT-D7 board (in slot C) is mandatory for the Grid Converter unit.

2.12.1 General
In master follower modes master is sending control word and DC Voltage reference to follower
drives. Follower drives send a status word to master including some command see details from
monitoring values description.
Start command is synchronized
Master sends run request to followers when all drives indicates that MCB is closed.
o Status is monitored even if follower do not have own MCB or status from the MCB.
If any of the drive goes state where MCB is needed to open all drives will open the MCB.
Control signals to follower drives
o DC voltage reference, can be selected in follower drive if used master or own reference.
2.12.2 Grid Converter Standard master follower In standard master follower mode modulation is not synchronized in any way through system bus
communication. This mode can be used when all the units can work independently but e.g. start and
DC-Link voltage reference is only wanted to give master drive and only four units are needed for
parallel operation.
3-LCL-filters are needed to use
Up to 4 parallel units.
2.12.3 Grid Converter DriveSynch In DriveSynch master follower modulation is synchronized between the drives, basically all follower
will do exactly what master will do.
3-pole LC-filters or standard sine-filters can be used instead of LCL-filters when common point
is connected to transformer.
Up to 4 parallel units.
2.12.4 Grid Converter D2-Synch In D2-Synch each unit operate independently only modulation switching is synchronised to eliminate

3.2 Terminal To Function (TTF)
The programming principle of the input and output signals in the Grid Converter Application is
different compared to the conventional method used in other VACON® NX applications.
In the conventional programming method, Function to Terminal Programming Method (FTT), you
have a fixed input or output that you define a certain function for. The applications mentioned above,
however, use the Terminal to Function Programming method (TTF) in which the programming
pro¬cess is carried out the other way round: Functions appear as parameters which the operator
defines a certain input/output for.

3.3 Defining inputs and outputs
Connecting a certain input or output with a certain function (parameter) is done by giving the
parameter an appropriate value. The value is formed of the Board slot on the VACON® NX control
board (see VACON® NX User Manual) and the respective signal number, see below.
Function name
Slot Terminal number
Terminal type
Example: You want to connect the digital output function Reference fault/warning (parameter
2.3.3.7) to the digital output DO1 on the basic board NXOPTA1 (see VACON® NX User Manual).
First find the parameter 2.3.3.7 on the keypad. Press the Menu button right once to enter the edit
mode. On the value line, you will see the terminal type on the left (DigIN, DigOUT, An.IN, An.OUT)
and on the right, the present input/output the function is connected to (B.3, A.2 etc.), or if not
connected, a value (0.#).
When the value is blinking, hold down the Browser button up or down to find the desired board slot
and signal number. The program will scroll the board slots starting from 0 and proceeding from A to
E and the I/O selection from 1 to 10.
Once you have set the desired value, press the Enter button once to confirm the change.

3.4 Defining a terminal in NCDrive
If you use the VACON® NCDrive Programming Tool for parametrizing you will have to establish the
connec¬tion between the function and input/output in the same way as with the control panel. Just
pick the address code from the drop-down menu in the Value column (see the Figure below).

Be ABSOLUTELY sure not to connect two functions to one and
same output in order to avoid function overruns and to ensure
flawless operation.

The drive output voltage.
V1.1.12 Line Frequency D7 Hz ID 1654
The measured line voltage frequency when using the OPT-D7 option board in slot C.
When the OPT-D7 board is not used, it is possible to use Analogue Input 3 and 4 ID
write function to give the grid the Line Frequency and Line Voltage. This enables use of
grid PI voltage controller without the OPT-D7 board. Note that both line frequency and
line voltages needs to be given. By activating Control Options 2 B2 these analogue
inputs can be used also to grid protection.
V1.1.13 Line Voltage D7 V ID 1650
The measured line voltage rms value when using the OPT-D7 option board in slot C.
When the OPT-D7 board is not used, it is possible to use Analogue Input 3 and 4 ID
write function to give the grid the Line Frequency and Line Voltage. This enables use of
grid PI voltage controller without the OPT-D7 board. Note that both line frequency and

4.2.2 Monitoring 2 values
V1.2.1 DC Voltage V ID 44
The measured DC voltage, unfiltered.
V1.2.2 Operation Mode ID 1615
The active Grid Converter operation mode.
0 = AFE operation
1 = Island operation
2 = Micro Grid Operation
V1.2.3 Used Current Ref % ID 1704
The used current reference. The value is negative to the set parameter to make the
monitoring easier in NCDrive since Active Current shows negative value when power
direction is from DC-Link to AC Line When the Current Reference mode is not used this
will show Active Current.
V1.2.4 D7 Synch. Error ID 1659
An error on voltage angles between the drive and the measurement taken by OPT-D7.
-3072...+3071 = -180...180 degrees.
If the value is not near to zero when running in AFE mode, the phase order may be
wrong even if the OPT-D7 frequency is correct (Error about 2047 = 120 degree). If the
measurement is after the Dyn11 transformer, the error is usually about 512 (30.0
Degrees).
V1.2.5 CosPhiActual ID 1706
The calculated Cos Phi.
V1.2.6 Unit Temperature °C ID 1109
The heatsink temperature of the drive.
V1.2.7 Frequency Reference Hz ID1752
The used frequency reference. In AFE mode, the frequency reference is determined
internally when the synchronisation is made. In Island and Micro Grid mode, the
reference is used for a static power supply, and a power drooping in Micro Grid mode.
V1.2.8 Current A ID 1113

2.1.1 Grid Nominal Voltage V ID 110
This parameter sets the incoming line voltage for the regenerative drive at the OPT-D7
connection point, drive terminal voltage is calculated internally.
Set this parameter to the nominal line voltage at the installation site. Used also as a
reference point for grid voltage protection functions. Use G2.2.8 Voltage Correction for
static voltage correction.
In Grid Converter Application Grid Nominal Voltage is not used as reference point for DC
Voltage Reference, therefore set also System Rated DC correctly P2.1.7 ID1805. This is
needed that AFE operation will work correctly and MCB is closed at correct voltage level.
See chapter Transformer Parameters.
Depending on system, transformer and especially selected start synchronization,
acceptable AC Voltage level may differ from normal when using Grid Code functions or
operating as a single power source for the grid.
2.1.2 Grid Nominal Frequency Hz ID 1532
Micro Grid and Island mode frequency set point. In Micro Grid mode used as a reference
point for the Base Current reference and drooping. In AFE mode used as a reference
point for frequency protection functions. Use G2.11 FreqDroopOffset for static frequency
adjustment.

2.1.3 System Rated Current A ID 113
Drive system rated current, recommended to keep default to have optimum control.
Grid Converter unit default values are fine tuned to its matching LCL filter and default
controls settings should not be changed unless using non-standard LCL filter.
The active current and the reactive current are scaled to this parameter as is the current
cutter level.
2.1.4 System Rated Cos Phi ID 120
Enter the system rated Cos Phi.
2.1.5 System Rated kVA ID 213
Enter the system rated kVA.
2.1.6 System Rated kW kW ID 116
Set the the rated active power of the system.
2.1.7 Nominal DC ID 1805
This value is used as a reference point for DC Voltage reference. Grid Nominal Voltage
is not used because System Nominal DC may not be connected to Grid Nominal
Voltage.
Recommended to set to highest DC Source voltage of the system to have common
reference point.
Based on:
Grid voltage: Grid Nominal Voltage * 1.35
Generator Voltage: Motor/Generator nominal voltage * 1.35
DC-DC Converter: Maximum battery DC voltage.
2.1.8 Parallel AFE ID 1501
Set this to 1 if more than one unit is connected to same DC bus.
0 = Single AFE
1 = Parallel AFE
When you select parallel AFE, DC drooping is set to 3.00% and modulation is
synchronised to reduce circulating current if the drives are in a common DC bus.

6.1.1 Transformer parameters These parameters are used to scale voltage so that the parameter P2.1.1 Grid Nominal Voltage can
be given a value as actual grid voltage. The drive will calculate the actual drive terminal voltage
based on these values.
NOTE: When ration is different than 1:1 also P2.1.7 System Nominal DC parameter must be given
so that MCB is closed at correct voltage level and AFE mode DC Voltage reference will give correct
DC-Link Voltage.
2.1.9 Transformer GC Side Voltage ID 1850

2.1.11 Transformer Phase Shift ID 1852
Set the transformer phase shift. Difference in angle, between U3 and U5. When OPT-D7
measurement is connected to U5 (i.e. to ship grid). This information is used if OPT-D7
assisted AFE start synchronization is activated. Usually Dyn11 transformer has 30.0

6.2 Reference handling
2.2.1 DC Voltage Reference ID 1462
This parameter sets the DC Voltage reference in % of the P2.1.7 System Nom. DC.
Final DC Voltage Ref (V1.1.2) = System Nom. DC * DC Voltage Reference
The DC Voltage will be maintained at this level when Grid Converter is running in AFE
mode.
There is internal limitation to reference: For 500V units the maximum limit is 797 Vdc and
for 690V units the maximum limit 1099 Vdc.
The maximum limit can be monitored from V1.1.15 DC Ref Max Lim.
NOTE! If DC voltage exceeds the values below in STOP state, the drive will lose READY
state:
• 797 Vdc for 500V unit, trip limit 911 Vdc
• 1099 Vdc for 690V unit, immediate trip limit 1200 Vdc, U2t protection above 1100 Vdc.
• 1136 Vdc for LC 690V voltage class 8 (Order code example: NXA15008_ _ _ _ _W)
NOTE! When transformer ration is different than 1:1 also P2.1.7 System Nominal DC
parameter must be given so that MCB is closed at correct voltage level and AFE mode
DC Voltage reference is giving correct DC-Link Voltage.
By default the internal DC voltage reference is kept the same as the actual DC voltage
when the drive is in STOP state, or the operation mode is Island or Micro Grid. This is to
make the change to the AFE mode smoother when the change is done on the fly.
2.2.2 Reactive Current Reference ID 1459
This parameter sets the reference for the reactive current in % of the System Rated
Current.
This can be used for power factor correction of AFE system or reactive power
compensation. Positive value gives inductive compensation whereas negative value
gives capacitive compensation.
In uGrid mode 100.0 % reactive reference will decrease voltage by set voltage drooping
value.
NOTE: Reactive Current reference does not affect voltage in island mode operation.

6.2.1 DC Reference Tuning
2.2.3.1 DC Drooping ID 620
When AFEs are used in parallel in independent mode, drooping can be used for current
balancing. The DCV voltage reference drooping is set as % of the active current
reference.
For example, if drooping is 3.00% and active current is 50%, the DC voltage reference is
reduced by 1.5%. With drooping, paralleled units can be balanced by adjusting the
DCVoltReference to slightly different values.

2.2.3.2 DC Voltage Ramp Rate ID 1199
This parameter defines the ramp rate for the DC voltage reference change. The rate is
defined as %/s. Firmware has separate fixed ramp rate 50 %/s.
By default the internal DC voltage reference is kept the same as the actual DC voltage
when the drive is in STOP state, or the operation mode is Island or Micro Grid. This is to
make the change to the AFE mode smoother when the change is done on the fly.

2.2.3.3 DC Voltage Reference Filter TC ID 1760
By default the internal DC voltage reference is kept the same as the actual DC voltage
when the drive is in STOP state, or the operation mode is Island or Micro Grid. This is to
make the change to the AFE mode smoother when the change is done on the fly.
This will prevent over current and current spikes when the control mode is changed.

2.2.3.4 DC Reference Offset ID 1776
Offset for DC Reference, used to balance parallel unit active current while using same
DC Reference P2.2.1. in all units.
6.2.2 Power / Frequency reference
2.2.4.1 Frequency Drooping Offset ID 1791
This parameter is used to adjust the base frequency for drooping purposes. For example,
if drooping is set to 2 Hz this parameter can be set to 1 Hz so that when the load is 50%,
the frequency will be at the nominal point. The offset can also be set by the supply
frequency parameters. However, in that case the grid frequency protection function will
also use this increased value as a reference point and makes the protection function
activate at the wrong frequency.
When you use this parameter for drooping purposes, the supply frequency can be left to
the nominal value.
Final frequency reference is also limited by G2.9.7 frequency warning limits.

P2.2.4.5 Freq. Max Adjust ID 1558
Maximum adjustment that Frequency MotPot function (ID417 & ID418) can make to
frequency reference.
2.2.4.6 Base Current Reference ID 1533
The Base Current Reference determines offset for frequency reference within Frequency
Drooping. For example, if frequency drooping is set to 2.000 Hz and grid frequency is
constant 50 Hz with very small or nonexistent changes (isochronous or strong grid), and
if 100% of Base Current Reference is given, the drive will feed 100% power to the grid.
The situation is the same with the frequency reference set to 52 Hz and with 2.000 Hz
drooping.
Base current reference can be used together with selection 3 of P2.11.5
StartPowerMode: Isochron.Gen. This selection will keep the drive frequency reference
same as the grid frequency, and the power that is fed or taken from the drive is solely
defined by the Base Current Reference parameter.

Island and Micro Grid: Not used.
P2.2.6.5 Inductor Size % ID 1461
AFE:
This parameter defines voltage losses in percentage of the nominal voltage at 100%
active current. This value is internally added to the reactive current reference thus giving
power factor 1 on the grid side, if set correctly together with Capacitor Size. The
transformer and feeding cables can be compensated by increasing this value.

2.4.2.9 NET Synchronisation ID 1602
This input is used to the synchronisation of the external network when the drive is
already generating network but in a different phase. It can be used only when OPT-D7
board is installed and measurements are on the external network side.
When the input is activated, the drive uses line frequency as a frequency reference and
adjusts the voltage angle to correspond with the line voltage angle with given hysteresis.
When there are parallel unit’s synchronization needs to be done by upper system. e.g. by
controlling Frequency Up and Down commands to all units (and other power sources in
the same grid).
2.4.2.10 NET Close Enabled ID 1705
An interlock for the NET contactor (shore). Used as information from Shore side if NET
close is allowed.
If the interlock is not used in the system, the option 0.2 = TRUE must be selected.
2.4.2.11 NET Close Request ID 1604
A command to close NET (shore) contactor. The closing will take place only when the
drive is synchronised to the grid (shore).
This function is needed when the drive is already making a grid and needs to be
synchronised to another grid that cannot be synchronised to the grid that the drive is
making.

The signal inversion function is useful for example in a situation where PLC sends power
limit to the drive by using analogue inputs. If PLC is unable to communicate to the drive,
the power limit is normally zero. When an inverted signal logic is used, a zero value from
PLC means maximum power limit. This allows you to run the drive, for example, from the
keypad without changing the power limit parameters.

Example:
All option board inputs are already in use, but you want to give a DI: DC Brake
Command (ID416). You also have a fieldbus board in the drive.
Set parameter ID891 (Fieldbus Digital Input 1) to 416. Now you are able to control DC
braking command from the fieldbus by Profibus control word (bit 11).
It is possible to control any parameter in the same way if values 0 = FALSE and 1 =
TRUE are significant for that parameter. For example, P2.6.5.3 Brake Chopper (ID504)
can be switched on and off using this function (Brake Chopper: 0 = Not Used, 1 = On,
