09.F5.B3A-RN01 by KEB

The 09.F5.B3A-RN01 is an axis drive module produced by KEB in the F5 Combivert Axis Drives series. It is intended for cabinet installation, where it conditions three-phase mains power and delivers regulated output to induction or synchronous motors, allowing motor speed and torque to be matched to changing process demands. The device supports material-handling lines, pump arrays, and coordinated multi-axis assemblies that require precise electrical control instead of mechanical throttling. Its regulated output also provides the controlled acceleration and deceleration needed in machinery with varying production cycles or fluid-flow requirements.

The drive employs a BASIC control structure based on open-loop flux vector control, so motor slip is compensated electronically without encoder feedback. Incoming power can vary from 305-528 V AC, allowing operation when feeder voltages fluctuate or regional mains standards differ. At its nominal supply level, the unit uses a 480 V three-phase input and maintains rated performance. The electronics support a line frequency of 50/60 Hz with a tolerance of ±2 Hz, helping the DC link remain within its intended operating range under either utility standard. These input ranges allow the drive to accommodate common industrial power networks while providing stable power conversion for the connected motor.

A compact housing with form factor code A keeps the footprint small, allowing multiple axis drives to be installed side by side in the same cabinet. The output stage can reproduce a three-phase voltage ranging from 0 V to 528 V, allowing drive parameters to match compatible motor ratings without external transformers. Integrated hardware includes a braking transistor that supports dynamic deceleration by directing regenerative energy to a compatible braking resistor. An internal EMI filter suppresses conducted electrical noise at the cabinet terminals and helps reduce interference with nearby control equipment. These integrated components reduce the need for separate filtering hardware and simplify the power connections required inside the enclosure.
