Product Description:
The RD52.2-5B-005-L-A2-FW is a drive controller manufactured by Bosch Rexroth Indramat and included in the RD 500 Drive Controllers series. As a closed-loop AC converter, the unit interfaces between a three-phase mains supply and induction or synchronous motors, delivering regulated current and frequency for speed and torque control. Within an automation cell, it coordinates motor motion, maintains process accuracy, and integrates with higher-level PLCs over standard control channels.
The drive uses a three-phase AC converter front end and operates across a nominal bus of 500 V, matching medium-voltage factory networks. An output rating of 5.5 kW states the maximum continuous motor power available under normal duty. Torque production is synchronized by an internal algorithm that uses field-oriented vector control, allowing rapid response to load changes and precise operation at low speed. Heat generated by the switching devices is removed through forced air cooling, so the unit requires a ventilated cabinet to keep internal temperatures within a safe range.
Application-specific safeguards are integrated at the hardware level. A built-in brake chopper dissipates regenerated energy during rapid deceleration and helps prevent DC-bus overvoltage. The controller belongs to generation 2, so installed option cards must match that release. Power management includes external standby power, which keeps the control electronics active from an auxiliary source while the main converter is isolated. A starting lockout circuit blocks unintended motor rotation after power-up.
