Product Description:

The 14.F5.K1E-3A5A is an axis drive from the F5 Combivert Axis Drives series manufactured by KEB. As a field-installed inverter, it interfaces between a plant controller and an induction or synchronous motor so torque, speed, and braking energy can be managed electronically during automation cycles. Within the series hierarchy, this unit’s size code 14 and housing form factor E indicate the mechanical envelope used to mount the drive in IP20 switchgear cabinets. This arrangement lets the controller manage acceleration, steady running, and controlled stopping through the same power electronics.

The drive is equipped with a Safety Board that adds certified STO functions directly on the power stage, and all control wiring lands on a 32-pole terminal strip to simplify cabinet routing. It can supply up to 10 HP of motor power on 230 V systems, a rating suitable for mid-range pumps, conveyors, and process mixers. Dynamic deceleration is handled by an internal braking transistor that channels excess DC-bus energy while limiting regeneration to a maximum of 21 A. For variable-torque loads, pulse-width modulation can be increased to a maximum of 16 kHz, which can improve current quality while increasing switching losses.

The thermal impact of those losses is capped by a total dissipation of 320 W, so forced-air cooling inside the panel is usually sufficient. Environmental ingress protection is limited to IP20, which means the drive must be installed in a clean electrical enclosure. During normal duty, the converter operates at a rated carrier frequency of 8 kHz, and this lower setting reduces switching stress while maintaining acceptable current ripple. To match the integrated chopper, the braking resistor network must not drop below 36 Ohm. Final safety wiring is completed through a 10-pole connector, and the wiring layout remains straightforward inside enclosed control cabinets.
