Product Description:

The 20.F5.A1H-340F is an axis inverter manufactured by KEB and supplied as part of the F5 Combivert Axis Drives series. It converts a three-phase mains supply into a regulated output waveform so that induction or synchronous motors can be started, accelerated, and held at commanded speeds in automated machines, material-handling cells, and process equipment. The standard control board in the size-20 hardware platform manages coordination between the control interfaces and the three-phase input network.

The drive accepts a line supply of 400 V. This matches typical plant distribution levels and avoids the need for step-down transformers. A continuous output rating of 75 A is available without thermal derating, while the general motor capacity of 50 HP refers to the largest standard motor size that can be controlled at 230 V in housing code H. Switching devices inside the inverter can be pulsed up to 8 kHz, which can smooth the current waveform but increases switching losses; this parameter can be reduced when efficiency is prioritized. The product meets electromagnetic compatibility requirements for installations classified as C1, and it provides two analog inputs, eight digital inputs, two analog outputs, and two transistor outputs for speed references, limit switches, and proportional commands. A braking transistor is mounted to absorb regenerated energy during rapid deceleration.

During acceleration bursts, the unit can source a peak current of 112 A, permitting short-term overload without tripping the drive. When lower noise and precise torque control are needed, the nominal switching frequency can be set to 2 kHz. All motor feedback, I/O, and safety circuits terminate on 29 control terminals, and the integrated encoder interface supports Hiperface for absolute position data exchange through a single hybrid cable. Auxiliary signal routing is completed through TTL-level outputs.
