Product Description:
The 18.F5.A1G-34-F is an AC axis inverter produced by KEB and assigned to the F5 Combivert Axis Drives series. In industrial automation, the drive converts fixed-frequency mains power into a regulated three-phase output whose frequency, voltage, and phase angle follow motion commands. This operation allows precise speed or torque regulation of induction or synchronous motors used in pick-and-place modules, conveyors, and material-forming stations. The inverter mounts vertically in a control cabinet and connects to higher-level controllers through standard fieldbus options.
Signal processing on this model is compatible with TTL auxiliary outputs, so incremental encoder channels can be monitored without extra level shifters. A factory-installed standard board provides the main processor, parameter EEPROM, and communication sockets required for closed-loop vector control. Rotor position feedback can also enter through the Hiperface interface, which carries absolute single-turn position data and high-resolution incremental signals to improve low-speed smoothness. This feedback arrangement helps the inverter maintain stable motor control during slow movement, acceleration, and changing mechanical loads. The mechanical depth, cooling surface, and terminal spacing correspond to inverter size 18, simplifying cabinet layouts where multiple F5 units are installed on a common backplate.
The housing code G indicates the frame height, mounting slots, and front-access terminal arrangement used for cabinet installation. Rapid deceleration energy is routed through the onboard braking transistor, so an external resistor can be connected when dynamic braking is required. This arrangement allows regenerated energy from the motor to be dissipated during controlled stops without adding a separate brake chopper. Within the Combivert F5 platform, the unit furnishes up to 30 HP at 480 V for pumps, mixers, gantry axes, and other motor-driven equipment. Its front-access terminals keep power, motor, and control wiring reachable after the inverter is mounted vertically in an enclosure.
