Product Description:

The 07.F5.B3A-0A0A is an AC axis drive module produced by KEB and supplied in the F5 Combivert Axis Drives series. As a stand-alone inverter, it regulates motor speed and torque for conveyors, packaging lines, and other motion tasks common in industrial automation cells. The unit belongs to the BASIC control category, so it executes standard V/F or sensorless vector routines without expanded application software. It is delivered in the compact A housing, which permits mounting with other F5 modules.

During continuous operation, the drive outputs 0.75 kW of mechanical power, aligning it with small induction motors used on auxiliary axes. The corresponding thermal design supports a steady motor current of 4 A, ensuring winding temperature remains within limits under rated load. Input energy is taken from a 1-phase 230 V AC or DC supply, allowing the same frame to be powered from rectified DC busbars when regenerative power is present. The IGBT bridge switches at 8 kHz, which reduces audible noise and improves current resolution at low speed. For fault ride-through events, the protection firmware permits an instantaneous overload up to 216%, giving the application brief torque boosts without triggering shutdown.

The rear aluminum fins form a heat sink, so cabinet airflow must remove the dissipation generated by high-frequency switching. Peak conduction capability reaches 8.6 A before the hardware current limiter acts, and a programmed short-time ceiling of 180% delivers extra torque margin during rapid acceleration. Electromagnetic emission is categorized as C1, meaning the integrated EMI filter meets limits for public low-voltage networks. A braking transistor is installed on the power board, enabling dynamic stopping without an external chopper. With no encoder interface provided, the drive relies on open-loop or sensorless algorithms to estimate rotor position, which simplifies wiring.
