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