Product Description:
The RD52.2-2B-003-L-A1-FW is a drive controller produced by Bosch Rexroth Indramat for the RD 500 Drive Controllers series. It is intended to regulate three-phase induction or synchronous motors in factory automation where precise torque and speed control are required. By processing feedback from the connected machine, the unit modulates power to the motor and coordinates with higher-level PLCs to maintain commanded motion profiles. This supports repeatable movement on conveyors, mixers, and positioning axes. It also helps reduce sudden mechanical stress during start-up, speed changes, and deceleration.
This controller uses a three-phase AC converter supply and operates within a line voltage range of 200 to 230 V. Motor flux and torque are regulated through field-oriented vector control, which helps the drive stay stable during rapid load changes and low-speed operation. The power section provides 3.0 kW of continuous output for small-to-medium motor sizes. Internal heat is removed by forced-air cooling, with airflow directed across the heat sink to support installation in compact cabinets. The cooling path keeps heat away from the power electronics during sustained operation.
A built-in brake chopper diverts regenerated energy to an external resistor, helping prevent DC-bus overvoltage during deceleration or overhauling loads. For machine safety, the logic supports external standby power with starting lockout, so control circuits and fans can remain active while the main inverter is disabled. The unit is built to design generation 2, which matches second-generation option cards, terminal layouts, and diagnostic functions used in this product line. This arrangement allows the drive to stay available for control and monitoring functions even when motor power is blocked. It also supports controlled stopping behavior on axes that return energy to the drive during braking.
