Product Description:

The RD52.1-5B-160-F-L4-FW belongs to the RD 500 Drive Controllers series and serves as a drive controller for three-phase induction or synchronous motor systems in industrial automation. It converts fixed-frequency mains power into a variable waveform so production machinery can adjust speed and torque in real time for conveyor lines, pumps, and machine tools. It operates on a DC link derived from a Converter 3 x AC supply and is intended for 500 V class grids, so associated power components must match that voltage level.

The controller is rated for 160 kW of output, indicating the maximum continuous power it can deliver to the connected motor. Speed and torque are regulated through field-oriented vector control, which aligns stator current with rotor flux to improve dynamic response during acceleration and changing load conditions. A built-in brake chopper dissipates regenerated energy during deceleration, helping prevent DC-bus overvoltage and reducing the need for external braking hardware. This operating method supports applications that require stable closed-loop motor control across varying process demands.

Thermal management uses forced-air cooling with integrated liquid circulation; fans move cabinet air across an internal heat exchanger tied to a liquid loop, keeping semiconductor temperatures within operating limits even at full load. The controller uses firmware ordered as a separate subposition, allowing the same hardware platform to be matched to different motion tasks without board-level changes. Control functions are expanded by the Combination: L1 + V1 + W1 set, which combines line-commutated rectification, speed feedback processing, and diagnostic capability. The unit is design generation 1, which supports compatibility with first-generation RD52 I/O and fieldbus accessories.
