La serie GD350-UL include High-performance vector invertersfor any type of electric motor and industrial application.
The result of more than 5 years of R&D work, the GD350 series is designed to meet any type of application requirement, even the most complex.
Innovative vector management algorithm with direct current control "I/F mode" (with or without sensor)the ability to control any type of motor (asynchronous or synchronous)and advanced torque control functions and the integrated positioner; allow the devices in this series to be used successfully in highly complex applications.
Infinite expansion possibilities
Built-in expansion slots allow you to increase the functionality of GD350 high performance vector inverters with communication extension boards (Ethernet, CANopen, Profibus, Profinet, EtherCAT, DeviceNet), feedback interfaces (incremental encoder, absolute encoder, resolver), I/O modules, integrated PLC board.
The Bluetooth module allows the inverter to be accessed and programmed by smartphone.
The integrated USB port allows simple and immediate connection to a PC for drive programming and monitoring.
Energy saving with ECO-MODE
The innovative ECO-MODE mode of operation available in the GD350 series can contribute, along with other interventions, to achieving the energy-saving goals set forth in the Transition 5.0 Plan, offering a noticeable advantage, in terms of consumption, over control modes with traditional Inverters.
ECO-MODE optimizes the efficiency of the motor-inverter system in a fully automatic way, acting directly and independently on the voltage/frequency curve and establishing the optimal V/F ratio for maximum motor efficiency under any load and speed conditions.
ECO-MODE allows the greatest energy savings in machines that do not require frequent acceleration and deceleration, allowing the system to self-regulate and, if necessary, autonomously shut down in the face of sudden changes in frequency and/or load.
Activation of the ECO-MODE function is done with a single parameter, no complex programming, no detailed knowledge of system dynamics. If the application allows it, ECO-MODE will allow the system to reduce its consumption totally autonomously, without impacting machine operation.
