Product Description:

The 12.F5.A1D-YBA3 axis drive is produced by KEB within the F5 Combivert Axis Drives series. The device functions as a field-oriented inverter that supplies regulated three-phase power to servo or induction motors in coordinated automation cells and other multi-axis machinery. It converts a constant DC link into variable amplitude and frequency output so connected axes can accelerate, decelerate, and hold process speeds under digital control. This role makes the unit suitable for material handling, packaging, and general motion stations that demand precise and repeatable profile execution throughout normal production cycles.

The inverter is designed for the 400 V AC/DC supply class and is identified by size code 12, making it suitable for machines that draw up to 5 HP under continuous load. For dynamic events, it can deliver a short-time current of 180% of its nominal value, allowing rapid torque surges without tripping. The IGBT bridge operates at a switching frequency of 16 kHz, which balances acoustic noise and semiconductor losses. Digital expansion is coordinated every 1 ms through the drive's I/O scanner, enabling close interaction with PLC cyclic tasks. These electrical parameters are handled by the internal inverter stage that follows the Combivert F5 control algorithms and supports stable response during commanded speed changes.

The enclosure carries an IP20 rating, so the drive is intended for installation inside a switch cabinet with controlled airflow and touch protection. Cooling is provided by convection, eliminating the need for forced fans. A factory-integrated braking transistor dissipates regenerated energy during deceleration, while the incremental and initiator encoder interface feeds back position to the Standard Board control section. The housing is classified as size D, and the terminal strip provides 17 connection points for power, logic, and fieldbus wiring in compact panel layouts.
