Product Description:
The 07.F4.C1D-1280 is a frequency inverter produced by KEB and supplied within the F4 Combivert Frequency Inverters series. It rectifies single-phase mains power and recreates a controllable three-phase output so that induction or synchronous motors can follow precise speed references. In industrial automation, this conversion allows flexible acceleration ramps, energy-saving partial-load operation, and electrical deceleration without relying on mechanical brakes.
This inverter belongs to the 230 V AC voltage class and is fed from a single-phase line that it converts to a three-phase output rated at 4.0 A. The power section handles an apparent load of 1.6 kVA, which supports a continuous mechanical rating of 0.75 kW at the motor shaft. Carrier modulation lets the drive raise output frequency to 816 Hz, enabling high-speed spindles that exceed the motor’s base frequency. Regenerated energy produced during fast stops is routed through a GTR7 braking transistor to an external resistor. Analog command inputs are sampled with 10-bit resolution for proportional speed control, while single-phase AC on the line side and three-phase AC on the load side are maintained without an autotransformer.
During short-term overloads, the inverter can deliver 7.2 A for 30 s, and the supply may draw up to 8 A under these conditions. Internal processing uses 15-bit digital resolution to refine current loops, fault thresholds, and ramp parameters. The electronics are housed in an IP20 enclosure that measures 90 × 250 × 160 mm, and this profile fits standard control cabinets while relying on panel airflow for cooling. Continuous service is supported up to +45 °C, and a built-in PTC evaluation circuit monitors motor thermistors so the drive can limit torque or issue a trip when winding temperature approaches unsafe levels.
