Product Description:
The 19.F5.C0R-760A is an AC inverter drive produced by KEB as part of the F5 Combivert Axis Drives series. Serving industrial automation, the unit converts fixed mains energy into a variable three-phase output so machine builders can match motor speed and torque to changing load conditions. By coordinating acceleration, steady-state motion, and controlled braking, the drive allows conveyors, extruders, and positioning axes to operate efficiently with tighter process control. Because output frequency and voltage are controlled together, the drive can respond to changing load conditions without abrupt speed shifts that could disturb upstream or downstream machine sections.
Rated for a three-phase input of 230 VAC, the inverter channels this supply through IGBT modules that switch at 8 kHz, producing a sinusoidal output current of 115 A under continuous duty. At this rating, the power delivered to the motor reaches 46 kVA, which is adequate for medium-frame machines supplied from this input class. Dynamic deceleration is handled by a built-in brake chopper that can conduct up to 132 A into an external resistor, helping manage regenerated energy during stopping. The IGBT switching stage gives the controller fast command response, which is useful in applications that alternate between constant-speed running and repeated acceleration or deceleration. Heat generated by the switching devices is removed through a dedicated heat-sink assembly, so cabinet ventilation must dissipate the thermal load effectively.
With a mechanical output ceiling of 40 HP, the model supports start-up surges to 172 A for brief acceleration profiles before settling at its nominal load. Those peaks require a braking resistor no lower than 3.0 Ω and a 160 A gG main fuse for protection. The internal heat sink may rise to 90 °C during operation, provided ambient air can move freely around the housing, and typical installations use 50 mm² motor leads suited to inverter size code 19 and compact housing code R. Proper airflow around the mounting area is important because accumulated heat can affect nearby electrical components. Even at full speed, only 1200 W of dissipation needs to be removed, and the enclosure has an IP20 rating that helps deter accidental contact with live parts.
