Product Description:
The 10.F5.B1B-3A0A is a three-phase inverter drive manufactured by KEB within the F5 Combivert Axis Drives series. Classified as an axis drive, it converts a fixed mains supply into a variable output for positioning and speed-controlled induction or synchronous motors in automated machinery. It is intended for applications that need adjustable acceleration, controlled deceleration, and stable motor response during changing load conditions. This makes it suitable for motion axes that must respond predictably to start, stop, and speed-change commands. With a maximum motor power of 3 HP, the unit fits medium-duty conveyors, small extruders, and similar motion tasks in automated systems.
Under rated operating conditions, the drive accepts a three-phase line of 400 V and draws an input current of 8 A through a 16 A gG main fuse. At this operating point, it delivers 5.8 A RMS to the motor, equivalent to 4.0 kVA of apparent power, while the insulated-gate bipolar transistors switch at 8 kHz. This combination supports continuous motor operation for routine duty cycles without forcing the inverter into overload operation. Thermal losses are 120 W, and the standby state draws 17 W when the control electronics remain energized. The unit includes an integrated braking transistor, so an external resistor no smaller than 82 Ω can be added for controlled deceleration. A minimum full-load output frequency of 6 Hz allows low-speed torque production, and inverter size code 10 is used for this model.
For transient events, the controller supports a maximum output of 12.5 A and a short-time current limit of 10.4 A, and it can operate at a switching frequency of up to 16 kHz when derating is acceptable. Reliable service is maintained while the heat sink temperature stays below 90 °C, and the IP20 enclosure provides finger-safe access while requiring cabinet installation. Cabinet mounting also helps shield the power section from accidental contact during normal machine use. When an 82 Ω braking resistor is fitted, the internal protection path routes regenerated energy to the dissipative load and keeps the DC bus within safe limits.
