Product Description:

The 19.F6.A33-3511 is an AC inverter drive manufactured by KEB as part of the F6 Combivert Inverter Drives series. Designed for induction and synchronous motors in automated machinery, the unit converts fixed mains voltage into variable-frequency, variable-amplitude output power, allowing closed-loop speed and torque regulation. The drive supports vector control, energy savings, and coordinated motion sequences without requiring a separate frequency converter. Its control capabilities make it suitable for demanding machinery that requires accurate motor response under changing speed and load conditions.

The drive connects to a three-phase supply at 400 V AC, drawing a rated input current of 66 A under nominal conditions. The unit delivers a continuous output current of 60 A, corresponding to an apparent power rating of 42 kVA and supporting motors rated up to 30 kW. When connected to a 480 V line, it has an input current of 57 A and an output current of 52 A. A transistorized GTR7 brake stage routes regenerated energy to a compatible braking resistor during deceleration, helping keep the DC-link voltage within safe operating limits. Two incremental encoder channels transmit rotor position data to the control card, enabling precise feedback for speed and torque regulation. The power semiconductors can operate at a high carrier frequency to reduce current ripple and audible motor noise.

System integration is handled by the EtherCAT fieldbus, enabling fast cyclic communication for command words, actual values, and safety telegrams. Functional safety is provided through a Type 3 module that implements Safe Torque Off and Safe Stop 1 functions directly in the drive. The enclosure measures 170 × 340 × 261 mm, providing a compact cabinet footprint for hardware in the 30 kW power class. The switching frequency can be set to 16 kHz, supporting smoother motor current and quieter operation when application conditions permit. Heat generated by the inverter is transferred through the integrated heat sink, while the cabinet must provide suitable airflow and installation clearances. The available encoder inputs, safety functions, and fieldbus connection allow the drive to coordinate motor operation with higher-level machine controls.
