Vector Inverter, Field Oriented

Crompton Greaves’ CG Drive SV Series represents an innovative field oriented Vector Inverter concept, capable of incorporating the needs of OEMs, system integrators and panel builders in order to make them more innovative and competitive in international markets. Thanks to its advanced functions, high level of precision and ultimate performance, CG drive SV is at the cutting edge of any application are where maximum motor performance and regulating sophisticated control architectures are an absolute must. It is extremely adaptable to every technical requirement of state-of-the-art process and control systems, not to mention that its extensive range and a series of specialised configurations successfully guarantee virtually universal automation solutions. Brief specifications: power range – 5.5 kW – 315 kW 230 V… 480 V 50/60 Hz; type of control – flux vector closed-loop with feedback, flux vector open-loop without feedback (sensorless), Scalar V/T; overload capacity – 150 Percent for 60 sec., programmable overload up to 200 Percent; switching frequency – up to 37 kW – 8 kHz (default)/15 kHz (programmable), 45 kW to 132 kW – 4 kHz (default)/8 kHz (programmable), 160 kW and 200 kW – 4 kHz (default), 250 kW and 315 kW – 2 kHz (default); output frequency – 500 Hz; braking module – integrated up to 55 kW; and optional above – 55 kW. General characteristics: off-line self tuning – of speed-current-flux regulators and motor data identification; on-line self-tuning – motor parameters compensation according to the temperature variation; torque control – with or built in function, for the gradual commutation, between speed and torque regulators; simplified start-up menu, motor and drive I2t thermal protection, multi-speed function, motor potentiometer function, flying restart function, droop function, double motor parameters setting, PID block function; and virtual and remote I/O management. Optional module: configurable I/O expansion cards, expansion cards for the management of auxiliary encoders, field bus interface cards on board or in “stand alone”, and configuration – Profibus, CANopen, DeviceNet, programmable application card.
