Product Description:
The 14.F4.F1E-4019 is an AC frequency inverter manufactured by KEB for the F4 Combivert Frequency Inverters series. As a COMBIVERT F4 unit, it converts fixed three-phase mains power into a modulated output that regulates induction motor torque and speed. By adjusting output frequency and voltage, it allows conveyor, pump, or fan speed to be controlled without mechanical throttling, reducing energy consumption and startup stress in automated equipment.
Closed-loop regulation is achieved with field-oriented control, a vector algorithm that continuously aligns stator current with rotor flux to maximize torque response. The electronics reside in the E-size housing, a mechanical frame that provides additional space for high-power components and simplifies wiring access. The inverter supports a motor output of up to 7.5 kW under the rated cooling conditions and with the appropriate wire sizes. Finger-safe terminals and the enclosure design provide an IP20 protection rating, limiting access to live conductors while keeping the inverter suitable for installation in a ventilated cabinet. The output stage uses a carrier frequency of 2 kHz, balancing acoustic noise, motor heating, and electromagnetic compatibility during operation.
Dynamic deceleration is handled by an internal braking transistor, so a separate chopper module is not required when the machine demands rapid stops or regenerative braking. The inverter supports continuous operation from -10 to 45 °C, allowing use in most production areas without auxiliary cooling, although output derating is required above this temperature range. Moisture tolerance reaches 95% relative humidity without condensation, supporting operation in humid industrial areas when the cabinet prevents direct exposure to water and allows sufficient ventilation. The drive’s parameter structure supports consistent configuration across compatible Combivert equipment, while its fieldbus options allow integration with industrial control networks. Proper cabinet spacing and airflow help remove heat from the power electronics during sustained motor loads.
