Product Description:
The 18.F5.L1G-340F drive is an axis inverter produced by KEB within the F5 Combivert Axis Drives series. It functions as a cabinet-mounted controller that rectifies incoming line power and modulates the output to operate servo or induction motors used in conveyors, packaging stations, and material-handling cells. Its integrated control loops allow automated equipment to coordinate torque, speed, or position without requiring additional motion modules.
For local signal processing, the inverter provides two analog inputs with a resolution of 12 bits and two analog outputs for proportional setpoints or diagnostic signals. Eight digital inputs, two digital outputs, and two relay outputs handle start, stop, and fault routing, while an auxiliary channel delivers a TTL-level square wave. Feedback from the motor arrives through the Hiperface encoder interface, allowing electronic nameplate reading and sinusoidal commutation. All I/O is scanned every 1 ms, and the connections are distributed across 29 control terminals to simplify wiring. A floating 24 V DC internal supply powers sensors and control electronics. An integrated braking transistor dissipates regenerated energy during rapid deceleration.
The inverter has a nominal output of 22 kW when connected to a three-phase 400 V mains supply. At the motor terminals, the unit can deliver up to 90 A during acceleration, while its 50 A continuous rated current supports sustained operation. The power stage switches at a nominal carrier frequency of 2 kHz, with a selectable ceiling of 8 kHz for machinery that requires lower audible motor noise. The mechanical layout uses inverter size code 18 and housing form factor G, allowing installation with compatible Combivert cabinet hardware. Its cabinet-mounted format supports orderly power and control wiring in high-density control panels while maintaining access to the terminals and cooling paths.
