Product Description:
The RD52.1-5B-005-L-NN-FW drive controller is manufactured by Bosch Rexroth Indramat as part of the RD 500 Drive Controllers series. Designed for panel mounting inside machine control cabinets, the unit interfaces with line reactors, contactors, and feedback sensors to command three-phase motors used in packaging, printing, and material-handling stations. It translates motion profiles generated by higher-level automation systems into inverter pulses, allowing rapid acceleration, constant running speed, and controlled deceleration while protecting the connected motor and mains supply. This cabinet-mounted arrangement keeps the power electronics close to external switching and feedback components without requiring the controller to be installed directly on the machine.
Its input section accepts a three-phase AC supply and is rated for grids up to 500 V, matching the power distribution used in heavier industrial equipment. The inverter can deliver 5.5 kW, and the control core uses field-oriented vector control to keep motor flux aligned during transient load changes. Heat generated by the IGBT modules is removed through forced-air cooling, so airflow clearances around the heat sink must be maintained for stable thermal performance. No auxiliary application-specific macros are listed, so the general-purpose parameter set remains available for direct control from a supervisory PLC. This makes the controller suitable for installations where motion sequences and timing are handled by the machine’s central automation logic.
A built-in brake chopper dissipates regenerative energy during abrupt deceleration, which can eliminate the need for an external resistor module in many applications. The unit belongs to design generation 1, so cabinet layouts that already use earlier RD52 versions can keep the same mounting geometry. Functional option slots are not equipped, leaving those positions open for future I/O or communication expansion. The base hardware can be installed without additional option cards when only the standard control and power functions are required.
