Product Description:
The 12.F5.B1D-1A0A is an AC axis drive module produced by KEB and supplied within the F5 Combivert Axis Drives series. This inverter regulates induction or synchronous motors used in machine tools, packaging lines, and material-handling cells by varying output voltage and frequency according to real-time command signals. By integrating power electronics with field-oriented control, the unit supports closed-loop speed or torque control without requiring mechanical gear changes.
The inverter accepts a 230 V AC input in either single-phase or three-phase form and delivers a rated motor current of 16.5 A, while overloads up to 35.6 A are tolerated for short acceleration periods. Pulse-width modulation is produced at a factory-set nominal switching rate of 8 kHz and can be elevated to 16 kHz when acoustic or control demands require finer resolution. Output frequency can be adjusted from zero to 800 Hz, allowing high-speed spindle operation beyond fundamental line frequency. The drive resides in a compact IP20 housing and includes an integrated braking transistor that dissipates regenerated energy into an external resistor to protect the DC link.
Control and feedback signals are processed on a dedicated 24 V DC logic rail. The control electronics achieve an I/O scan of 2 ms, coordinating up to five digital inputs, two relay outputs, and a single analog channel with 11-bit resolution for speed or torque references. The analog capture pairs with an EMC category C1 filter set to minimize conducted emissions on public networks. With frame size 12, the drive can energize motors up to 5 hp from the same 230 V bus, while its auxiliary circuitry remains powered by a stabilized 24 V DC supply during maintenance or fieldbus downtime.
