Product Description:
The 07.F4.F1D-3240 is an AC frequency inverter built by KEB as part of the F4 Combivert Frequency Inverters series. It works as a variable-speed drive that modulates output frequency and voltage to control induction or permanent-magnet motor torque in automated equipment. Integration with PLC-based control loops allows electronic speed regulation for conveyors, small pumps, and light processing axes, reducing the need for mechanical speed changes and supporting smoother process adjustment during operation.
In normal service, the inverter uses a three-phase mains supply and is rated for the 230 V class supply range. Field-oriented control governs the stator current vectors, which supports smooth low-speed operation and responsive torque behavior during acceleration and load changes. At the output, it delivers a continuous line current of 4 A, corresponding to a nominal apparent power of 1.6 kVA. The internal IGBTs switch at 8 kHz, which helps keep motor current ripple low even at slow shaft speeds. Protection functions include an overcurrent trip and an integrated braking transistor for handling regenerative energy, while housing type D provides the mounting footprint and airflow path used for this frame size.
Motor sizing for this drive reaches 0.75 kW, and the unit dissipates only 65 W of internal power during operation. When rapid stops are required, a brake resistor of 56 Ω can absorb regenerated energy while keeping the braking circuit within its intended operating range. The heat sink can reach a maximum of 85 °C before derating begins, so continuous operation depends on suitable panel airflow and ambient conditions. The control algorithm maintains stable torque across the speed range, and the compact footprint supports dense cabinet layouts where several drive modules must fit in limited space.
