Product Description:

The RD52.3-9C-160-W-V1-FW is a high-power drive controller produced by Bosch Rexroth Indramat for cabinet installation. It regulates torque, speed, and direction for large AC machines used in pumps, extruders, and heavy conveyor lines. By converting fixed-frequency mains power into controlled output for the connected motor, it supports automated processes that need stable electrical performance under changing load conditions. In large process systems, this allows upstream controls to adjust motor behavior smoothly during startup, loaded operation, and controlled deceleration.

The controller uses field-oriented vector control, which separates stator current into torque-producing and flux components for fast dynamic response. A continuous power rating of 160 kW makes it suitable for demanding industrial motors that operate under sustained load. Heat is removed by liquid cooling, which helps keep internal temperatures stable during extended operation and reduces the amount of heat released into the cabinet air. The unit is built in Design generation 3, indicating a third-generation hardware platform. It also uses externally supplied 24 V stand-by power so the control electronics can remain active while the main DC bus is disconnected.

The drive is configured for RD51 SFT mode, so its parameter structure and diagnostic display follow the RD51 platform. Its designation as an SFT inverter means the unit contains inverter sections for use in common DC bus systems. The required control software comes as a separate software package, so the selected version can be matched to the intended application. The unit also supports series-specific option cards, fieldbus interfaces, and engineering tools, and it keeps identical mechanical footprints for cabinet retrofits. This layout helps preserve panel fit and cable routing when the drive is integrated into existing equipment.
