Product Description:

The 16.F4.C1G-4001 frequency inverter is produced by KEB within the F4 Combivert Frequency Inverters series. Designed for three-phase AC motors, the unit converts fixed mains power into a variable-frequency output, allowing automated machines to regulate motor speed and torque as process demands change. By integrating with the DC-voltage link common to this series, the inverter supplies controlled energy to conveyors, pumps, and material-handling drives found in industrial manufacturing cells.

For signal-level integration, the inverter offers 2 analog inputs that accept speed or torque reference voltages and a complementary 1 analog output that can retransmit feedback such as actual current. Discrete control is handled through 4 digital inputs for start, direction, or preset selection, while a single 1 digital output can flag status to a PLC. Motor voltage is synthesized with pulse-width modulation, so switching edges regulate the effective RMS value without relying on mechanical tap changers. The internal DC bus follows a DC-voltage link topology, enabling built-in braking components and filtering, and the compact frame houses a dedicated brake transistor and DC braking circuitry to absorb regenerated energy during rapid stops.

The logic layer extends control flexibility through 2 relay outputs that isolate higher-level alarms or ready signals from the low-voltage electronics. Parameter design is structured into 11 parameter groups, and machine builders can store up to 8 parameter sets for rapid configuration changes between products or batches. Thanks to its compact construction and hardware current limit, the drive maintains a small footprint while helping prevent overcurrent faults when large inertial loads accelerate. These features allow the same unit to serve different motor duties while reducing panel space and wiring complexity.
