Product Description:

The 14.F5.M1E-3AEA is an axis drive produced by KEB within the F5 Combivert Axis Drives series. It functions as a field-oriented inverter that regulates three-phase induction or synchronous motors in automated machinery, supplying variable frequency and voltage to match real-time load demands and motion profiles on production lines, conveyors, and process equipment. This operating method supports controlled acceleration, deceleration, and stable speed regulation across a wide range of machine duties.

This unit is built on inverter size code 14 and uses a heat-sink cooling arrangement that directs thermal energy into a finned aluminum base. The housing follows form factor code E for compact cabinet mounting, and the integrated braking transistor allows dynamic retardation when a discharge path of at least 25 Ω is provided. Under continuous operation, the drive can energize motors up to 10 HP. Rated switching takes place at 8 kHz, and carrier modulation can be increased to 16 kHz when lower acoustic noise or reduced torque ripple is needed. A minimum output frequency of 6 Hz keeps fan and pump shafts turning during idle cycles, while field-oriented motor control maintains accurate performance from zero speed to the maximum operating range. The heat sink may rise to 90 °C before thermal limits are reached, and its 320 W of internal dissipation must be removed by cabinet airflow. With a 400 V input, the converter supplies 11 kVA of apparent power and has an installed mass of 5 kg.

Cable routing can span up to 100 m between the drive and motor without exceeding reflected-wave voltage limits, which supports distributed layouts on large cells. Rated mechanical output is 7.5 kW, delivered through an RMS phase current of 16.5 A. Short-term transients are covered by a peak capacity of 29.7 A during acceleration or load shocks. This current reserve helps the drive handle temporary overloads while maintaining controlled motor operation.
