!
CAUTION!
This active front end has an earth leakage
current which does exceed 3.5 mA AC.
Therefore the minimum size of the protective
earth conductor must comply with the local safety
regulations for high leakage current equipment which
means that according to the standard IEC61800-5-1 the
protective earth connection must be assured by one of
following conditions:
PE conductor cross-sectional area shall for phase cable
size < 16 mm2(6 AWG) be >10 mm2Cu (16 mm2Al) or
use a second PE conductor with same area as original
PE conductor.
For cable size above 16 mm2(6 AWG) but smaller or
equal to 35mm2(2 AWG) the PE conductor cross-
sectional area shall be at least 16mm2(6 AWG).
For cables >35 mm2(2 AWG) the PE conductor cross-
sectional area should be at least 50 % of the used phase
conductor.
When the PE conductor in the used cable type is not in
accordance with the above mentioned cross-sectional
area requirements, a separate PE conductor should be
used to establish this.
!

2CG Drives & Automation 01-7318-01r1
Voltage tests (Megger)
Do not carry out voltage tests (Megger) on the motor, before
all the motor cables have been disconnected from the active
front end and variable speed drive.
Condensation
If the active front end or motor inverter is moved from a
cold (storage) room to a room where it will be installed,
condensation can occur. This can result in sensitive
components becoming damp. Do not connect the mains
voltage until all visible dampness has evaporated.
Incorrect connection
The Active front end or motor inverter drive is not protected
against incorrect connection of the mains voltage, and in
particular against connection of the mains voltage to the
motor outputs U, V and W. The Active front end or motor
inverter can be damaged in this way.
Power factor capacitors for improving
cosϕ
Remove all capacitors from the motor and the motor
outputs.
Precautions during Auto-reset
When the automatic reset is active, the motor will restart
automatically provided that the cause of the trip has been
removed. If necessary take the appropriate precautions.
Transport
To avoid damage, keep the active front end and motor
inverter in its original packaging during transport. This
packaging is specially designed to absorb shocks during
transport.
IT Mains supply
The Active front end can be modified for an IT mains
supply, (non-earthed neutral), please contact your supplier
for details.
Heat warning
DC-link residual voltage
Be aware of specific parts on the Active front
end and motor inverter having high
temperature.
WARNING!
After switching off the mains supply,
dangerous voltage can still be present in the
Active front end-AFR/AFG or motor inverter-
AC drive. When opening the equipment for installing
and/or commissioning activities wait at least 7 minutes.
In case of malfunction a qualified technician should
check the DC-link or wait for one hour before
dismantling the AFR/AFG or AC drive for repair.

2. General description
The Emotron active front end (AFE) is a regenerative active
front end unit designed to be used either in combination
with Emotron motor inverter (VSIs) i.e. VFX/FDU or
without Emotron motor inverter (VSIs). The main objective
of the Emotron AFE is to rectify the supply AC voltage into
DC voltage to be fed to or regenerated from the VSIs. This
is achieved with the minimal impact on the supply by the
control of the active rectifier module which provides
sinusoidal input currents with a very low harmonic content,
typically a THD(I) below 5%. Different variants of
Emotron active front end drives are:
AFR: Regenerative, low harmonic active front end
without Emotron motor inverter.
AFG: Regenerative, low harmonic active front end
without Emotron motor inverter. AFG offers full/
advance grid support functionality.
FDUL: Non-regenerative, low harmonic drive including
active front end (AFR) together with Emotron
motor inverter FDU.
VFXR: Regenerative, low harmonic drive including active
front end (AFR) together with Emotron motor
inverter VFX.
FDUG: Regenerative, low harmonic drive including active
front end for generation (AFG) together with
Emotron motor inverter FDU. FDUG offers full/
advance grid support functionality.
VFXG: Regenerative, low harmonic drive including active
front end for generation (AFG) together with
Emotron motor inverter VFX. VFXG offers full/
advance grid support functionality.
CAUTION!
Always consult CG Drives & Automation
before connecting an Emotron AFR/AFG to a
standard VSI.

2.1 AC drive types
2.1.1 Standard AC drive (as
comparison)
A standard AC drive consists of a rectifier module and an
inverter module. The rectifier module (front-end) consists of
a 6-pulse diode bridge, i.e. diode front-end (DFE) while the
inverter module (VSI) consists of IGBTs with anti-parallel
free wheeling diodes, see Figure 2. The main advantages of
DFEs are the simple and robust design together with their
high efficiency, i.e. low losses. The main disadvantages are
unidirectional power flow and the high harmonic content in
the line current, typically THD 30- 40%.
Fig. 2 Standard AC drive.
2.1.2 AC drive with AFR or AFG
(FDUL/VFXR/FDUG/VFXG)
An AFE unit is basically a VSI towards the supply (via a
filter) where the IGBTs are used as an active rectifier, see
Figure 3. The main advantages are inherent 4Q-operation,
i.e. bi-directional power flow, and sinusoidal supply
currents, i.e. low harmonics, regeneration and improved
power factor.
The AFE unit is controlled in such a way to keep the energy
between motor and supply in balance. This is achieved by
controlling the DC-link voltage (Udc). Other features are
the possibility for reactive power compensation and boosted
DC-link voltage.

2.1.3 AFR
AFR consists of Emotron power electronic module (AFE)
connected to grid through LCL filter as shown in Figure 4.
The main objective of the Emotron AFR is to rectify the
supply AC voltage into the DC voltage to be fed to or
regenerated from the VSIs (motor inverter). It also keeps the
harmonic content of the current exchanged with grid at low
level, maintaining the THD(I) below 5%. AFR offers
standard AFE functionality such as:
-Activepowercontrol.
- Reactive power control.
- Low harmonic operation.
Fig. 4 AFR
2.1.4 AFG
AFG is an AFE variant that offers full/advance grid code
functionality. This variant (AFG) is dedicated for generation
applications where generated energy (through DC-link) is
fed into the utility grid. AFG consists of Emotron power
electronic module (AFE) including voltage measurement
board and brake chopper switch (optional) connected to
grid through LCL filter as shown in Figure 5. Main objective
of AFG is to feed in generated power from DC-link to
utility grid fulfilling the grid code requirements. AFG offers
standard AFE functionality along with full grid support
features such as:
• Grid voltage and frequency (U, F) protection.
• Reactive power (Q) control.
• Anti-islanding protection.
• Grid fault ride through (FRT) capability.

The Emotron low harmonic and regenerative AC drive i.e.
FDUL/VFXR/FDUG/VFXG is comprised by an AFR or
AFG unit i.e. AFE and filters and a VSI, i.e. Emotron VFX
or FDU. The concept is designed as a cabinet solution, see
Figure 6.
Fig. 6 Single drive in cabinet
where
• Cabinet - IP54 cabinet with door fans
• Q1 - Main switch *
• K1 - Main contactor *
•RFI-EMCfilter
•LCL-LCLfilter
• F2 - MCB (Miniature circuit breaker) for pre-charge
circuit
• AFE - Emotron AFE module with 24V standby supply
board, voltage measurement board (optional), brake
chopper switch (optional) and integrated pre-charge
circuit (K2,D2,R2)
• AFR/AFG - Emotron AFE and filters
• VSI - DC-voltage fed VSI module, i.e. Emotron VFX or
FDU
• CB - Control board
• SBS - Standby supply board
• Lo - Output coil
* For larger units, Q1 Main switch and K1 Main contact are
replaced by Q1 Motorized circuit breaker.
2.2.2 Common DC-bus applications
For common DC-bus applications, the cabinet will contain
only the AFR/AFG part of Figure 6, i.e. all except the VSI &
Lo.

AFR/AFG = AFE + LCL
FDUL/VFXR = AFR + VSI (FDU/VFX)
FDUG/VFXG = AFG + VSI (FDU/VFX)
NOTE:
For AFG/FDUG/VFXG, supply voltage measurement
board (SVMB) is mandatory. It is mounted and
connected internally to K2.

2.3 Emotron AFR/AFG concept
Emotron also offers only AFR/AFG solution for the
applications where complete FDUL/VFXR/FDUG/VFXG
drive train is not required. In this concept, the DC power
load/source is connected to the DC-terminals of AFR/AFG.
AFR/AFG consists of AFE power electronic module and
LCL filters as main components along with other necessary
components. AFR/AFG concept is shown in Figure 7.

• Q1 - Main switch *
• K1 - Main contactor *
•RFI-EMCfilter
•LCL-LCLfilter
• F2 - MCB (Miniature circuit breaker) for pre-charge
circuit
• AFE - Emotron AFE module with 24V standby supply
board, voltage measurement board (optional for AFR
and mandatory for AFG), optional brake chopper switch
and integrated pre-charge circuit (K2, D2, R2)
• AFR/AFG - Emotron AFE and filters
• DC source/load - External DC power source or load
based on the application.
• CB - Control board
• SBS - Standby supply board
* For larger units, Q1 Main switch and K1 Main contact
are replaced by Q1 Motorized circuit breaker.
