The modules have plug-in connector, meaning fast
and easy assembling.
Standard resistors are also available, but non-standard
resistors can used, how ever they must checked
case-by-case.1 110 kW,
and all the powers from 2000 are different
configurations R8i units, single parallel.
In the diode supply units (DSU) only four different
types unit, either single parallel, cover the
pow range 145 4200 380 690 V. Common
braking includes the possibility for regenerative braking
and motor-to-motor braking depending the motor
loads the line-up.
Product range
Invertermodules
Inverter modules are available different frame sizes. passive ode the converter
operates the rectifier.2009 Drive modules 19
.7.
Harmonic content remains extremely low due DTC
control and LCL filtering.Multidrive modules, ACS800
The ACS800 multidrive module product series includes
rectifier- and DC-supplied inverter modules and
accessories especially designed for integrators, OEMs
and panel builders.
This concept also allows pre-installation the power
cables the empty cabinet. The
voltage range covers 380 500 and 690 V. power control gives the same firm
and gentle perform ance DTC gives motor control.
The power module hardware com patible with
the inverter module.
The thyristor supply unit (TSU) used regenerative
drive systems.
Supplymodules
Supply modules are available diode-, thyristor- or
IGBT- based solutions.
The ACS800 multidrive principle based com on
DC bus arrangement enables single pow entry and
com braking resources for several drives. the active ode the IGBTs
are controlled keep the voltage constant and the
line current sinusoidal.
The basic features the diode rectifier unit include
automatic adaptation 12-pulse operation and
automatic control charge the inverter capacitor
banks during start-up.
The pow range from 1975 in
380 690 Modules are single parallel connected. This means limited
number different module sizes and fewer spare parts.
Frame sizes R2i R7i start from 1.
The mechanical dimensions are the same each
module, making engineering and assembling very easy.
Braking choppers and resistors
In resistor braking henever the voltage the
intermediate circuit frequency converter exceeds a
certain limit, braking chopper connects the circuit to
a braking resistor. contains two 6-pulse thyristor bridges
in antiparallel connections.
Special design for system integrators
The design these modules based much smaller
inverter modules.
Besides the com pact design, the new ACS800 DC-
supplied inverter and rectifier units include an
extensive selection options. The modules are also equipped
with heels, they can easily pulled out the
cabinet and pushed back for aintenance purposes. The pow range from 470 to
3150 380 690 V.
3A FE68404592 REV 3.
An Supply unit (ISU) used fully regenerative
drive systems.
Inverter and diode modules can freely connected
parallel for higher output current. 12-pulse units can also be
configured.
The modularity, com pact size and simplicity the
modules means lot savings for cabinet builders in
terms minimizing the num ber cabinets and the
widths
