Product Description:
The 18.F5.K1G-345F is a three-phase inverter drive produced by KEB within the F5 Combivert Axis Drives series. The unit serves as the central speed and torque regulator for induction or synchronous motors on automated lines, allowing a PLC to modulate frequency and voltage at the motor terminals. Integrated power electronics, feedback ports, and application-specific control boards allow the unit to manage medium-power motion axes while keeping command and position signals within the drive architecture. This configuration supports coordinated motor operation in machinery that requires controlled acceleration, steady speed regulation, and accurate response to changing loads.
The auxiliary signal port transmits incremental position data as TTL-level pulses, ensuring direct compatibility with standard PLC high-speed counters. A dedicated safety board occupies the control slot, so the drive can execute safe torque off and related stop functions without separate safety relays. Rotor feedback enters through the Hiperface protocol, providing single-cable transmission of absolute position data and encoder power for position referencing after startup. The rated output is 30 HP, which is the maximum continuous motor shaft power available when the inverter is supplied from a 480 V bus. To dissipate regenerated energy during deceleration, an internal braking transistor is installed. This semiconductor diverts excess DC-link voltage into an external resistor, helping prevent an overvoltage condition when the connected motor slows rapidly or operates with an overhauling load.
The mechanical footprint uses the 18 inverter size code, which sets the frame height, mounting-hole pattern, and cable entry locations. Within that frame, the cabinet depth corresponds to the G housing form, allowing uniform airflow paths across drives that have the same physical arrangement. This layout supports consistent cable routing among multiple axes and keeps the power conductors separated from lower-voltage feedback and control wiring. Connector placement reserves accessible space for the encoder, I/O, and communication interfaces without requiring the power terminals to be disturbed. The organized terminal layout also helps maintain suitable bend radii for incoming cables and preserves cooling clearances around the drive inside the control cabinet.
