Product Description:
The 18.F5.A1G-34DA is a three-phase inverter from KEB in the F5 Combivert Axis Drives series. This unit acts as the power stage between the line supply and an AC motor, converting fixed-frequency input voltage into variable voltage and frequency for position-controlled or speed-controlled machinery. In servo and vector applications, it regulates motor torque and speed by adjusting the output to match control commands. Variant D and housing code G place the drive in the medium-power class of the platform, making it suitable for packaging lines, material-handling axes, and other automation tasks that require accurate torque regulation.
On the supply side, the drive accepts three input phases at a rated input voltage of 400 VAC and draws 65 A continuously from the line. This current supports 30 HP operation at both 400 V and 480 V and matches size code 18 with an 80 A fuse. Heat-sink cooling keeps the module below 90 °C, while an overcurrent threshold of 90 A protects the IGBTs. The integrated EMC filter and standard control board help reduce electrical noise and simplify wiring. A built-in braking transistor can route up to 63 A into an external resistor of at least 15 Ω. The switching devices operate at 2 kHz to balance acoustic noise with switching losses.
Motor terminals deliver an output rated current of 50 A, which corresponds to an apparent power capability of 35 kVA in the 400 V class. For heavy acceleration or regeneration, the inverter can deliver a short-time current of 75 A for several seconds before thermal foldback begins. An LCD operator with serial and CAN connectivity and a peak-output display supports local parameter entry, diagnostics, and network integration. The interface gives direct access to status messages and operating values during use. The control firmware logs thermal and current events, providing a clear operating history for fault tracing. The consistent footprint helps the drive fit cabinet layouts where panel space is limited.
