Product Description:

The 07.F4.S1D-4B11 is an AC frequency inverter manufactured by KEB and assigned to the F4 Combivert Frequency Inverters series. It accepts a fixed mains input and synthesizes a variable-frequency, three-phase output, allowing controllers to match induction motor speed and torque to the real-time demands of conveyors, pumps, or small material-handling axes. By replacing mechanical throttling methods with electronic regulation, the unit minimizes energy losses, limits inrush currents during starts, and provides the fast ramp profiles required in modern industrial automation cells.

The inverter has an IP20 protection rating, so it must be mounted inside a closed control panel where contact with live parts is prevented. Reliable operation is permitted from -10 to 45 °C; staying within this range prevents thermal derating and keeps semiconductor junction temperatures within design limits. The power section can drive motors up to 0.75 kW, making the model suitable for light-duty feeders, indexing tables, or cooling fans. A carrier frequency of 2 kHz balances motor acoustic noise against switching losses and supports stable current control without excessive heat buildup in the inverter or connected motor windings.

The control algorithm operates in Standard mode, providing fixed-parameter V/Hz regulation that simplifies setup when advanced vector features are unnecessary. For networked installations, the drive includes an InterBus interface that enables set point transfer and status feedback over a single two-wire trunk. The Compact D-size housing fits narrow enclosures while providing space for the required wiring clearances. Dynamic deceleration of overhauling loads is handled by an internal braking transistor; an external resistor converts the resulting kinetic energy into heat. The design tolerates ambient relative humidity up to 95% without condensation, allowing the electronics to operate in non-air-conditioned production areas.
