Product Description:

The 09.F5.CBB-3A0A belongs to the F5 Combivert Axis Drives series engineered by KEB for closed-loop speed and torque regulation on small-to-medium induction or synchronous motors in industrial automation cells. Classified by KEB as a compact axis drive, it integrates a heat-sink cooling section so that it can be panel mounted without additional airflow hardware. Its role is to translate higher-level control commands from a PLC into the pulse-width-modulated voltage pattern that the connected motor requires for precise acceleration, deceleration, and continuous running. This operating role makes it suitable for indexing tasks, feed control, and repeatable speed regulation in compact machine layouts.

For power entry, the unit accepts a three-phase 400 VAC/DC supply, and that line voltage is converted into a rated apparent power flow of 2.8 kVA toward the motor terminals. Under continuous duty, the inverter supplies a rated output current of 4.1 A, with switching devices operating at a carrier frequency of 8 kHz to keep current ripple low. The drive can modulate the output to any frequency up to 599 Hz, allowing operation of high-speed spindles or servo motors that demand extended field-weakening ranges. That range allows one unit to cover both steady conveyor duty and faster rotary applications when it is paired with an appropriate motor.

During transients, the drive supports a maximum motor rating of 1.5 kW and a short-time phase current ceiling of 7.4 A. Dynamic stops are supported through the braking IGBT, which can sink up to 7.5 A into an external resistor no smaller than 120 Ω. Braking energy is therefore diverted outside the drive, so the resistor must match the deceleration demand of the application. The heat-sink path keeps semiconductor junctions below 90 °C. The compact housing measures 90 × 220 × 161 mm, leaving room in the enclosure for the 16 A mains fuse, control wiring, and any required contactors.
