Product Description:

The 15.F5.A1E-354A is an axis inverter assembled by KEB for the F5 Combivert Axis Drives series. Designed for industrial automation cells, the unit converts a fixed mains supply into a pulse-width-modulated output that commands synchronous or induction motors up to 15 horsepower. By modulating voltage and frequency, the drive provides closed-loop speed and torque control required for packaging lines, material handling stations, and positioning tables. This operating method supports repeatable axis motion where stable acceleration and controlled low-speed performance are important.

This inverter is built around the standard board control platform and arrives in housing code E, a form factor that matches the size-15 power stage. It can draw energy from an AC or DC link and is optimized for a nominal 400 V bus. Under rated conditions, the drive delivers 24 A of output current, while momentary demands are covered by a 150 % short-term current reserve and a peak of 36 A. Switching devices may be pulsed up to 16 kHz, although the factory rating is 4 kHz to reduce losses. Overcurrent protection trips at 180% of rated current, safeguarding the power module and the standard forced-convection cooling path. With these margins, the unit operates motors up to 15 HP on 400 V systems and maintains the same horsepower on 230 V circuits when configured as Unit B.

Electromagnetic compatibility is reinforced by the C1 emission classification, allowing the drive to share cabinets with sensitive control electronics. Position feedback from motors is received through the TTL and SSI encoder interface, supporting closed-loop speed and position control during dynamic operation. A factory-installed GTR 7 braking transistor dissipates regenerated energy during rapid deceleration, which helps manage braking events on axes with frequent speed changes. Connection to a three-phase mains network completes the power path, so the inverter can be integrated into a wide range of industrial installations.
