Product Description:
The 36.F5.A1P-90-D is a high-capacity axis drive manufactured by KEB as part of the F5 Combivert Axis Drives series for heavy industrial automation. The unit converts fixed three-phase mains power into a variable output that controls large induction or synchronous motors in material-handling systems, test stands, and process equipment. Acting as the power interface between the plant supply and motor, it regulates speed, manages regenerative energy, and receives motor position data through its incremental TTL encoder port. Its high-current power stage supports demanding machinery that requires controlled acceleration, steady operation under heavy loads, and coordinated motor feedback.
The drive accepts a three-phase input of 400 V AC, matching common factory power distribution and eliminating the need for an external transformer. Its rated current of 1150 A supports continuous operation and establishes the thermal requirements for connected busbars and cables. The power devices operate at a rated switching frequency of 2 kHz, balancing electrical efficiency with motor noise. An enclosure rating of IP20 provides protection against accidental finger contact but requires installation inside a suitable control cabinet. The drive also conforms to EMC class C2 requirements and includes short-circuit and ground-fault monitoring for the connected power circuit.
During transient load peaks, the inverter can supply 1438 A, providing additional current for rapid acceleration without an immediate overload trip. When lower motor noise is required, the carrier can be raised to its maximum switching frequency of 4 kHz, although the resulting thermal load must be considered. The power section can deliver 630 kW for high-horsepower compressors, extruders, cranes, and other large industrial machines. Cold-start operation is supported at temperatures as low as -10 °C, allowing installation in some unheated operating areas. An integrated braking transistor routes regenerated energy to an external braking resistor during motor deceleration. The housing uses size 3 × P for cabinet planning, while a TTL auxiliary signal output and the standard control board architecture support connection to the surrounding control system.
