Product Description:

KEB manufactures the 09.F5.B1B-UK05 as part of its F5 Combivert Axis Drives series. This drive regulates induction or synchronous motors in multi-axis machinery, supplying adjustable frequency power so that speed, torque, and direction follow the command profile generated by a PLC or motion controller. By integrating control, protection, and braking circuitry in a compact module, it provides a single component that handles both motor excitation and feedback interfacing within automated production lines.

Low-level control resources are available on a 24 V auxiliary bus. The port supplies 24 VDC and can deliver up to 100 mA, which is enough for sensors or encoder reference channels. Two differential analog inputs have an 11-bit resolution and are refreshed every 2 ms, allowing the drive to react quickly to setpoint changes. The analog output stage has a source resistance of 100 Ω, so external controllers can measure actual speed without excessively loading the circuit. Digital control lines are protected by 2.1 kΩ input resistors that limit current during wiring faults. A built-in braking transistor dissipates regenerated energy, while relay contacts rated to 1 A at 30 VDC offer galvanically isolated status feedback to supervisory equipment.

Power handling is sized for machinery axes up to 1.5 kW, and the inverter can modulate output frequency from 6 Hz to 1600 Hz, so both low-speed positioning and high-speed spindle tasks are supported. Continuous apparent power is 2.8 kVA, which matches typical three-phase supply sections in compact cabinets. Heat is transferred through an aluminum heat sink that may reach 90 °C before the unit derates, so the cabinet must provide adequate airflow clearance during operation. The motor line terminals accept 1.5 mm² cable to minimize installation space while still carrying the required current. An analog output channel can source 5 mA for tachometer loops, and the relay driver is energized by the same 24 V bus used for the control electronics.
