Product Description:

KEB manufactures the 16.F6.A12-3511 as part of the F6 Combivert Inverter Drives series. The unit is an AC inverter drive that converts fixed-frequency mains power into a variable-frequency, variable-voltage output so that an automation controller can adjust induction or synchronous motor speed and torque in real time. It targets conveyors, pumps, extruders, and similar equipment that demand compact motor control at the cabinet level while sharing mechanical options with other frames in the modular F6 platform. Its cabinet-mounted format also suits installations where motor control must fit into limited panel space without moving power electronics onto the machine.

At the electrical interface, the drive is designed for a three-phase supply of 400 V, matching standard industrial grids. Its power stage supports a rated apparent output of 22.9 kVA, which corresponds to continuous shaft power of 15 kW when a four-pole motor is connected. Under these conditions, the output can deliver up to 33 A rms while switching at a carrier frequency of 4 kHz to limit motor acoustic noise. The internal circuitry includes the Application control board, allowing user-defined logic blocks and fieldbus links to reside inside the inverter. The unit uses inverter size 16 within the series, giving a footprint suitable for medium-power cabinets without resorting to the larger frame 17.

The mechanical enclosure uses housing size 2, allowing size-16 power modules to share common mounting holes and airflow paths in multi-axis cabinets. For personnel protection, the unit integrates a safety module classified as Type 1, enabling basic safe torque off functionality through dedicated terminals. During motor acceleration, the power stage dissipates 329 W, and when the machine is inactive but still energized, the standby circuitry draws only 27.10 W. These values are useful for enclosure cooling calculations and for estimating standby energy use in continuous-duty installations.
