Product Description:
The RD52.2-5B-018-L-A2-FW drive controller is built by Bosch Rexroth Indramat within the RD 500 Drive Controllers series. It interfaces between a mains supply and three-phase motors by shaping output voltage and frequency to match load demand. In this role, the unit conditions incoming power and provides controlled output for variable-speed motor operation. This helps production equipment maintain stable torque regulation, efficient speed ramps, and coordinated motion in automated lines.
Rated output reaches 18.5 kW, indicating the continuous power available to the connected motor. This level suits medium-power industrial drive tasks where steady motor performance is required across changing load conditions. The DC link is derived from a three-phase supply centered on 500 V, which suits higher-voltage plant networks. Motor regulation uses field-oriented vector control, a method that separates flux and torque for responsive current control and accurate low-speed operation. A built-in brake chopper directs regenerated energy to an external resistor during deceleration or overhauling loads. Temperature is managed by forced-air cooling, so cabinet airflow helps keep power semiconductors within a safe operating range during continuous switching.
The unit is supplied as a 3 × AC converter, which means it rectifies and inverts three-phase mains power without an integrated transformer. It belongs to design generation 2, so the control card, power modules, and option slots follow the second-release layout used for this hardware platform. System auxiliaries benefit from external stand-by power, which keeps logic circuits energized from a small auxiliary source while the main bus is isolated. Together with a starting lock-out contact, this arrangement helps keep the power stage disabled until operating conditions are correct. Application firmware is not embedded, and firmware must be ordered as a separate subposition so the selected functions, communication options, and diagnostics match the intended use.
