Product Description:
The 09.F5.B3A-RN01 axis drive is built by KEB and belongs to the F5 Combivert Axis Drives series. It serves as the inverter section between the plant supply and an AC motor, converting fixed mains power into regulated motor voltage and current. This conversion allows the drive to control shaft speed and torque according to commands from the connected automation system. The unit is suitable for pumps, fans, conveyors, and other material-handling axes that require adjustable motor operation. Its enclosure is intended for installation in a closed control cabinet with the necessary ventilation and electrical protection. Standardized fieldbus connectivity allows the drive to exchange commands and operating data with compatible machine controllers.
The drive operates from a nominal input of 480 V three-phase power and accepts an input range of 305 to 528 V AC. This range allows the unit to operate with supported industrial power systems while accommodating normal line-voltage variation. Compatibility with regional power networks is supported by a frequency rating of 50/60 Hz ±2 Hz. Motor magnetizing current is calculated through BASIC open-loop flux vector control, which estimates rotor flux without requiring encoder feedback. This control method reduces feedback wiring while improving torque regulation at lower motor speeds compared with basic voltage-to-frequency control. The drive adjusts its output in response to speed and torque commands while monitoring internal operating conditions. Protective functions can respond to unsuitable supply conditions or excessive loading before the power stage is damaged.
Excess kinetic energy returned by a decelerating motor is handled through an integrated braking transistor, which permits connection to the appropriate braking circuit. Conducted electrical noise is reduced by the onboard EMI filter, helping limit interference transferred through the supply wiring. The unit uses frame code A, providing a slim housing with a consistent mounting-hole pattern and heat-sink depth for multi-axis cabinet layouts. On the motor side, the inverter produces a three-phase output from 0 V to the supply voltage. Its output voltage reaches up to 528 V, allowing operation across the supported supply range when paired with a compatible motor. The narrow housing helps conserve panel width, while the rear heat sink transfers operating heat away from the internal power electronics. Cabinet airflow and installation clearances must remain sufficient to prevent excessive temperature around the drive.
