Offering a control drive system with a U/f curve, the unit has a type-1 design and a nominal voltage accommodating 380-480 Volts at a margin of +/-10%. With a pulse frequency of 4 kHz, the unit covers an output frequency range of 0-250 Hz, extending to 0-500 Hz at 8 kHz. Equipped with a PROFIBUS-DP communication interface, it efficiently controls electric motors with effective monitoring. Ideal for assembly systems, machine tools, packing machines, and process technology, it shouldn't be used in extreme or inconsistent temperature conditions or underwater. While it lacks an integrated brake chopper, it includes a 24 Volts external standby power unit. It uses a forced air-cooling mechanism for cooling and complies with the EN 61800-3 standards for noise immunity, with an IP protection class of 20. It should be handled by accredited professionals due to its high-voltage nature. Comes with a one-year global warranty.
