Product Description:
The 20.F5.A1R-76-A is an AC axis drive module manufactured by KEB for the F5 Combivert Axis Drives series. It functions as an inverter that converts three-phase mains power into a variable-frequency, variable-voltage waveform for a connected motor. Under PLC command, the drive adjusts motor speed and torque during acceleration, steady operation, deceleration, and controlled holding. In industrial automation systems, it serves as the power stage for conveyors, spindles, positioning axes, and other motor-driven equipment that requires regulated motion. The drive processes control commands and supplies the corresponding motor current without requiring a separate inverter stage between the control system and the load.
The drive delivers up to 50 HP at 230 V when connected to the designated supply network. Its installed Standard Board provides the baseline I/O set, encoder interfaces, and logic functions without optional expansion cards. Housing code R indicates a slim, book-style enclosure that conserves panel width and supports side-by-side mounting with compatible drive modules. During deceleration, the internal braking transistor switches regenerative energy to an external resistor rather than returning that energy to the mains. This braking arrangement helps prevent excessive DC-bus voltage during short stopping cycles while keeping the heat-producing resistor outside the drive enclosure. Appropriate cabinet airflow must pass through the designated cooling clearances so heat from the inverter power stage can dissipate during continuous operation.
The inverter carries size code 20, which corresponds to the busbar dimensions, electrical connections, and cooling clearances used for this frame. Its modular architecture centers on a pluggable Control Board that houses command processing, encoder interfaces, and configurable input and output circuits. Separating the control electronics from the power section keeps low-voltage signal connections organized while leaving mains conversion within the primary chassis. The controller receives commands from the connected PLC and processes motor feedback to regulate current throughout the commanded motion profile. Standard connection points also support orderly routing of motor, control, and braking conductors within the installation panel.
