Product Description:

The 18.F5.C1G-Y02F is an AC axis drive released by KEB and assigned to the Combivert F5 series. It serves as the power and control interface between a plant-level controller and an induction or synchronous motor, delivering regulated torque and speed for material handling, packaging, and forming machinery. In operation, the drive executes vector-control loops, processes encoder feedback, and manages regenerated energy through hardware already integrated in the unit. This arrangement lets the higher-level controller issue motion commands while the drive handles motor response directly at the axis. It can be used with either induction or synchronous motors, which supports different axis requirements within the same machine platform.

The auxiliary position or speed reference leaves the drive as a TTL square-wave signal, so counters or PLC inputs can accept it without extra level shifting. Rotor position returns through a Hiperface encoder interface, which supports absolute multi-turn data and automatic electronic nameplate exchange. When connected to a 480 V AC supply, the unit supports motors up to 30 HP. The inverter uses size code 18, which identifies the silicon current capacity and cooling surface assigned to this frame. The feedback channel allows the drive to read rotor information directly instead of relying only on an open-loop speed reference. These control and feedback features support closed-loop motion tasks that require both stable reference signaling and continuous position tracking.

Mechanical layout follows housing form factor code G. This housing sets the frame height, mounting hole pattern, and airflow direction so the module fits standardized control cabinet layouts, and it also fixes the cooling path used by this enclosure size. A factory-mounted braking transistor switches surplus DC-bus energy into an external resistor during fast deceleration cycles, helping control bus voltage during stopping and reversing. During rapid deceleration, this helps prevent excess regenerative energy from remaining on the DC bus for too long. The integrated braking hardware is useful in machines that see repeated speed changes, short cycle times, or frequent commanded deceleration.
