Product Description:

The 09.F4.T60-1009 is a frequency inverter manufactured by KEB and assigned to the F4 Combivert Frequency Inverters series. The device converts fixed line power into a variable-voltage, variable-frequency output so that the speed of three-phase induction motors can be matched to process demands in automated machinery. Within industrial automation, it serves as a front-end controller that interacts with PLC commands, enabling energy-efficient acceleration, deceleration, and steady-state operation across diverse load profiles.

Its power section accepts a supply of 3 x 500 V AC and can deliver a continuous motor current of 8 A. Because the unit is wired to a 3-phase mains network, torque ripple at the motor shaft remains low and dynamic response stays linear over the full frequency range. Input harmonics are attenuated through an integrated HF filter, while the additional designation 460 V Class identifies differential-mode filter elements sized for use near North American 480 V systems. These filtering components reduce conducted noise and help protect adjacent drives, sensors, and communication hardware from electromagnetic interference that can corrupt signals or trip protection circuits.

Electromagnetic compatibility on the installation floor is further supported by compliance with EN 55011/B, a limit that permits placement in environments where residential-grade emission thresholds are required. When the inverter is connected to the motor with a shielded lead up to 30 m, reflected-wave voltage remains within safe limits and helps prevent premature insulation breakdown. Mechanical integration is simplified by the submount housing coded D, which aligns with modular heat-sink plates and allows rear cooling through a cabinet wall to conserve space. This layout helps move heat away from internal control components, and the unit remains consistent with the design approach used in KEB drives.
