Product Description:

The 09.F5.B1B-3A0A is an axis drive module from the F5 Combivert Axis Drives series manufactured by KEB. The unit converts fixed mains power into a regulated output for AC servo and induction motors, enabling closed-loop speed and position control in packaging lines, conveyor zones, and pick-and-place stations. By integrating power electronics and a braking transistor, the drive holds regenerated energy within safe levels during fast deceleration events, supporting precise motion profiles in industrial automation.

Electrically, the drive accepts a three-phase supply of 400 V and delivers a rated apparent power of 2.8 kVA. With a continuous motor output of 1.5 kW at a rated current of 4.1 A, it matches small to medium axis requirements. The integrated braking transistor is paired with a minimum external resistor of 120 Ω to dissipate surplus kinetic energy. Heat produced by normal operation is quantified at 80 W of overall power dissipation, while DC supply loss stands at 75 W. The electronics switch at a nominal carrier frequency of 8 kHz, and wiring is accommodated by a 1.5 mm² motor cable cross-section. A compact footprint of 90 × 220 × 160 mm and an IP20 enclosure allow installation inside protected cabinets without additional shielding.

For brief overload conditions, the inverter can supply a peak phase current of 7.4 A, providing additional torque for acceleration or shock loads. When higher dynamic response is required, the pulse-width modulator can be configured up to 16 kHz, trading lower acoustic noise for increased switching losses. Thermal design limits the heat-sink surface to a maximum of 90 °C; above this threshold the unit will derate or shut down to prevent damage. During idle periods, the electronics draw only 17 W, minimizing standby energy consumption. The internal losses are carried away through the rear finned cooler, maintaining operation within normal limits.
