ACS 2000 – simple and reliable motor control
The ACS 2000 is the latest member of the ABB medium voltage
AC drives family providing reliable motor control for a wide range
of applications.
The ACS 2000 is designed for high reliability, easy installation
and fast commissioning reducing the total cost of ownership.
With the integration of an Active Front End (AFE), line side
harmonics are minimized without the use of expensive, spe-
cialized transformers and with the added benet of regeneration
and power factor correction.
With its compact footprint, the ACS 2000 can be retrofitted
to control standard induction motors via a direct connection
to 4.0 – 6.9 kV line supplies (direct-to-line). Alternatively, the
ACS 2000 can be operated with an input isolation transformer
to allow for flexible line side power voltages. It is available with
an integrated transformer or it can be connected to an external
two-winding transformer.
The ACS 2000 direct-to-line combines the cost savings of a
transformerless variable speed drive system with the benefits
of Voltage Source Inverters (VSIs), including excellent availability and reliability, high and constant power factor and
superior dynamic control performance.
The heritage of ABB’s VSI topology, along with a patented
IGBT-based multi-level control, provides a proven track
record for reliable and motor friendly medium voltage AC
drive solutions.

Key features
The ACS 2000 general purpose drive offers unique features
which provide superior application flexibility with a standard
solution.
Line supply connection flexibility
The ACS 2000 provides different line supply connection
options, each offering unique benefits. The ACS 2000 is
available for connection to an external input isolation
transformer, with an integrated input isolation transformer
or for use without a transformer. The latter allows a direct
connection to the industrial line supply (direct-to-line).
Direct-to-line
The ACS 2000 direct-to-line can lower investment costs substantially. Due to its compact size and lighter weight compared
to a drive requiring a transformer, it also results in lower transportation costs and needs less space in the electrical room.
The ACS 2000 can be easily retrofitted to fixed speed motors
while the direct-to-line technology results in quick and easy
installation and commissioning.
For operation with a transformer
External transformer
For applications where a voltage-matching input transformer
is needed or galvanic isolation from the power supply is
required, the ACS 2000 can be connected to a conventional
two-winding oil or dry-type converter transformer.
Integrated transformer
Alternatively, the ACS 2000 is also available with an integrated
input isolation transformer.

efficient operation
The ACS 2000 is available with an Active Front End (AFE)
which can be used in conjunction with a simple input isolation
transformer or for direct connection to 4.16 or 6.0 – 6.9 kV line
supply. It provides low harmonics and enables regeneration and
reactive power compensation.
Low harmonic signature
The AFE provides a low harmonic signature which meets the
most stringent requirements for harmonic distortion as defined
by relevant standards. This avoids the need for harmonic analysis
or the installation of network filters.
Regeneration
For applications with high braking energy, the ACS 2000 is
available with optional regeneration capability, which feeds back
braking energy to the line supply. This further reduces the overall
energy consumption.
Power factor correction
For applications where other loads connected to the same line
supply cause leading or lagging power factor, the ACS 2000 is
available with a static VAR compensation option. With static
VAR compensation, a smooth line supply voltage profile can
be maintained and reactive power penalties can be avoided.
Powerful performance with DTC
Precise and reliable process control, together with low energy
consumption, results in top performance. The ACS 2000 drive
control platform uses ABB’s award-winning Direct Torque Control
(DTC), resulting in the highest torque and speed performance
as well as the lowest losses ever achieved in medium voltage
AC drives. Control of the drive is immediate and smooth under all
conditions.
Motor friendly output waveform for use with new or
existing motors
The ACS 2000 provides near sinusoidal current and voltage
waveforms making it compatible for use with standard motors and
cable insulation. This is achieved with ABB’s patented multilevel
topology which utilizes one DC link enabling a multi-level output
waveform with a minimum number of power components.
