Product Description:

The 14.F5.A1D-38GA is an AC inverter drive manufactured by KEB and assigned to the F5 Combivert Axis Drives series. It regulates the speed, torque, and braking of induction or synchronous motors used in automated machinery. In operation, it converts a fixed three-phase supply into the controlled output needed for variable-speed motor duty. The unit is intended for compact motor-control applications in conveyors, pumps, and positioning axes where braking and protective functions are needed in one package.

During normal operation, the drive accepts a three-phase input of 400 V AC at a rated line current of 23 A. Internally, the IGBT bridge switches at 2 kHz, producing the controlled output used to supply a continuous motor current of 16.5 A and an apparent power of 11 kVA. The standard control board handles the basic control functions and available fieldbus options. Size code 14 identifies the mechanical envelope, and the mounted unit measures 296 mm in height and 90 mm in width, which helps conserve cabinet space in this power range. This combination of current capacity and enclosure size suits cabinet installations where usable panel area is limited.

Dynamic events are handled by the integrated braking transistor, which can sink up to 15 A through an external resistor no smaller than 56 Ω. This braking path dissipates regenerated energy during deceleration and supports controlled stopping on loads with repeated speed changes. Short acceleration bursts are supported by a maximum current of 29.7 A, and the drive disconnects at an overcurrent threshold of 35.6 A to protect the power stage. The protective trip point limits stress on the switching components if the motor or wiring draws excessive current. A 25 A gG main fuse is recommended on the supply side. The assembly weighs 2.8 kg, so it adds little load to cabinet mounting hardware and fits compact enclosure layouts.
