Product Description:
The 04.F5.S3A-2I2B is an axis drive module manufactured by KEB for the F5 Combivert Axis Drives series. Intended for synchronous motor control, it conditions incoming power and commands motion profiles so that machine axes follow precise speed and torque references in automated production lines. Its protective hardware and communication channels allow the unit to link a central controller with the motor while providing fault handling and energy dissipation through its built-in braking circuit.
The drive accepts a single- or three-phase 230 V AC or DC supply, making it suitable for utility feeds or plant power buses. Its output stage operates at a carrier frequency of 8 kHz, which limits torque ripple while controlling conduction losses. Control algorithms are refreshed every 1 ms, so the current, velocity, and position loops receive frequent updates for tight regulation. Protective electronics trigger at an overcurrent threshold of 480% of the nominal rating. The inverter can also sustain a short-term current of 400% of the nominal rating to accommodate rapid acceleration or impact loads. An installed braking transistor dissipates regenerated energy, while the integrated EMI filter helps limit conducted electrical interference without requiring separate external components.
Position feedback is processed with a 32-bit resolution, providing fine interpolation when both encoder inputs are used. Each channel accepts an incremental TTL signal through terminal connectors, supporting common rotary or linear encoders. Five digital inputs receive discrete control signals, while one analog input and one analog output exchange continuously varying commands and process values with connected equipment. Actuators or indicators can be driven by two open-collector outputs, and a separate relay contact provides an additional switching interface. Heat is removed through the flat, varnished rear cooling design, permitting dense back-panel mounting without external air ducts and protecting the treated surface from contaminants commonly found inside industrial control cabinets.
