Product Description:
The 12.F5.B3D-1A0A is an axis inverter manufactured by KEB for the F5 Combivert Axis Drives series. It regulates the speed and torque of induction or synchronous motors in automated machinery such as positioning tables, conveyors, and process lines. A dedicated braking stage and electromagnetic interference suppression are housed within the same frame, allowing the drive to manage dynamic stopping without external modules. This integrated layout also helps conserve panel space in compact machine installations.
During operation, the drive is fed from a three-phase 230 V AC/DC supply and maintains its electronics through a separate 24 V DC control supply. The power channel delivers a continuous motor current of 16.5 A and switches at a carrier frequency of 8 kHz to reduce audible noise and torque ripple. For short acceleration peaks, it tolerates up to 180 % of rated current, and the built-in GTR 7 braking transistor helps dissipate regenerated energy during deceleration. Five digital inputs accept limit switches or start commands, while two relay outputs send status signals to the master controller. The unit is assembled in size code 12, provides 17 screw terminals, and includes a wired EMI filter. No encoder interface is present, so closed-loop encoder feedback is not available directly at the drive.
For safety, the overcurrent trip engages at 216 % of nominal current to help prevent semiconductor damage during stalls or external faults. The drive scans its fieldbus and discrete I/O every 2 ms, which supports fast response to control changes in coordinated motion tasks. Its housing carries an IP20 rating, so it must be installed inside a switchgear cabinet while remaining accessible for wiring. A varnished protective coating shields the electronics from condensation, and the thermal design supports motors up to 5 HP. Filtering, rapid current sensing, and onboard parameter memory are integrated into the same chassis.
