Product Description:

The 16.F4.C1E-4M00 inverter is produced by KEB and belongs to the F4 Combivert Frequency Inverters series. As a frequency inverter, it modulates the voltage and frequency supplied to three-phase induction motors so conveyor lines, pumps, and fan drives can be matched closely to process demands. By adjusting the output waveform in real time, it supports energy savings and torque optimization across a wide speed range in industrial automation cells that require a compact cabinet-mounted drive. This operating method also helps smooth acceleration and deceleration, which can reduce mechanical stress on couplings, belts, and other connected machine components. Because motor speed can be varied electronically, the drive can help match airflow, fluid movement, or conveyor throughput to the actual needs of the machine instead of running the motor at a constant line frequency.

The drive is rated for 400 V supply lines across three input phases, and it draws a nominal input current of 36.5 A under full load. Conductors up to 10 mm² can be landed on the terminals, and upstream protection uses a 50 A mains fuse to limit fault energy. On the motor side, the inverter can deliver up to 15 kW of shaft power while generating output frequencies as high as 409.58 Hz. The three-phase input arrangement and terminal capacity make the unit suitable for medium-power cabinet installations where reliable wiring, stable motor control, and flexible speed adjustment are required. That combination is useful in applications where one drive platform may be assigned to different motor types or where process equipment needs both standard operating speeds and overspeed capability during specific production steps.

Further application flexibility comes from the integrated braking transistor, which allows a dynamic resistor to dissipate regenerative energy during rapid deceleration. The inverter has a nominal output current of 33 A, and its apparent power reaches 23 kVA, which supports demanding centrifugal loads and similar duty profiles. It can store 8 parameter sets internally, and its onboard I/O includes two programmable analog inputs, four digital inputs, one digital output, and two relay outputs for direct connection to sensors and contactors. Stored parameter sets let the drive switch between different operating profiles for separate products or motion sequences, while the built-in control points support direct signal exchange with local machine devices. The enclosure is rated IP20, so it is intended for installation inside a control cabinet where the electronics remain protected from accidental contact.
