Product Description:
KEB manufactures the 20.F5.M0R-56G0 as part of the F5 Combivert Axis Drives series. This unit is a DC-supplied inverter that processes control signals, modulates motor voltage, and coordinates feedback to run medium-power machines on automated lines. By placing power electronics, PLC-level I/O, and encoder interfaces in one housing, it simplifies cabinet layouts and supports coordinated motion for motors up to the 50 horsepower class.
The drive’s two analog input channels work at a resolution of 12-bit, allowing fine scaling of speed or torque commands from external sources. Eight discrete control channels are available through 8 digital inputs, and the internal processor completes a full I/O refresh every 1 ms. This short cycle helps maintain tight loop response even when multiple axes share the fieldbus. Power arrives on a DC bus rated at 400 V DC, and the inverter section can energize induction or permanent-magnet motors up to 50 HP. Two analog outputs echo operating variables for external indicators, while dual relay and dual transistor outputs forward status or fault flags to interlocking circuits. Encoder port 2 supports 300 kHz signal streams with a 150 Ω termination, and the base configuration relies on standard incremental encoders.
An overcurrent trip threshold set to 180% of nominal protects the power stage, and a short-time current margin of 150 percent permits brief acceleration surges without shutdown. Gate pulses switch at 8 kHz, balancing acoustic noise against thermal dissipation. The R-form housing measures 520 mm high, 340 mm wide, and 355 mm deep, matching inverter size code 20 for this frame class. Two transistor outputs and two relay contacts share the front terminal strip, and encoder port 2 includes a hardware disable to prevent unintended wiring when closed-loop control is not used.
