Product Description:
The 20.F5.A1H-340A is an axis drive inverter produced by KEB and assigned to the F5 Combivert Axis Drives series. It is intended to regulate induction or synchronous motors in automated machinery, providing speed and torque control from a compact housing that mounts inside centralized or distributed electrical panels. By matching motor characteristics with programmed parameters, the unit supports precise acceleration, deceleration, and holding functions in conveyors, winders, and material-handling cells. It can be used where coordinated motion must stay stable during changing load conditions, repeated starts, and controlled stopping cycles. This makes it practical for packaged machine sections where cabinet space is limited.
This model is equipped with a Standard Board control card, so parameter handling and fieldbus connectivity follow the baseline feature set for the platform. Its general maximum motor output is rated at 50 HP, allowing the drive to energize medium-frame machines without external paralleling modules. The mechanical outline follows housing form factor code H, which sets the heat sink length, mounting hole pattern, and terminal spacing. An integrated braking transistor diverts regenerated energy into an external resistor during rapid deceleration to help prevent DC-link overvoltage. The descriptor Inverter Size Code groups the unit's electrical and dimensional classification in a simple format that is easier to read.
Within size designation 20, this drive carries a secondary output rating of 50 HP at 230 V for low-voltage mains operation. The marking Unit B identifies this rating variant within the enclosure family and separates it from versions intended for a different supply class. Keeping the size and voltage-related rating together makes the enclosure assignment clearer when the same basic housing is used across more than one electrical version. It also keeps the low-voltage entry distinct within the range while the drive continues to provide the same core motor-control functions.
