Product Description:
The 14.F5.M1E-3AJA axis drive is produced by KEB and belongs to the F5 Combivert Axis Drives series. This inverter converts fixed mains energy into variable voltage and frequency so that three-phase induction or synchronous motors follow programmed speed and torque profiles inside automated production cells. Its control electronics handle power conversion, protection, and fieldbus communication in a single enclosure that mounts directly in a control cabinet. This layout lets the drive manage motor output and protective responses without requiring separate power-conversion modules for the same axis.
The drive accepts a three-phase supply of 400 VAC and draws a rated input current of 23 A. It delivers 16.5 A of continuous current, which corresponds to 11 kVA of apparent power at the motor terminals. Gate drivers operate at a rated switching frequency of 8 kHz, and an optional setting raises the carrier to 16 kHz when lower motor noise is needed. The synthesized output frequency reaches 599 Hz, which supports high-speed spindle operation. A short-time current limit of 29.7 A supports acceleration peaks, and the integrated braking transistor routes regenerative energy to an external resistor. That braking path helps control bus voltage when the motor decelerates or an overhauling load feeds energy back into the drive. Under typical loading, the E-form-factor housing dissipates 320 W of thermal loss, so cabinet airflow must carry that heat away from adjacent components.
Motor sizing guidelines rate the unit for 10 HP on a 230 V network when it is wired as a Unit B inverter. Two differential analog channels provide 12 bit resolution against a 10 VDC reference, and an analog PWM output is available at 3.4 kHz for external regulators. Eight digital inputs present 2.1 kΩ impedance and are scanned every 1 ms to capture fast edge transitions. These input and output channels let the drive exchange reference, status, and control signals with surrounding automation hardware. At full load, direct-current conduction losses rise to 295 W while short-term switching events remain within the nominal margin. The unit uses a size-14 power stack and includes an installed braking transistor.
