Product Description:
The RD52.1-4B-200-F-V1-FW is a drive controller produced by Bosch Rexroth Indramat within the RD 500 Drive Controllers series. The unit serves as the central power and regulation stage between plant mains and an AC motor, delivering vector-based torque commands that support tightly regulated speed and position loops in industrial automation. This arrangement is suited for high-power axes that must respond smoothly to changing loads during continuous production. The control structure also supports stable motor behavior during acceleration, deceleration, and constant-speed operation while helping keep cabinet layouts compact and wiring straightforward.
At its core, the RD52.1 hardware of design generation 1 employs field-oriented vector control, allowing the inverter stage to separate flux from torque so current response remains stable during rapid load changes. The controller accepts a three-phase AC converter supply within a line window of 380 to 480 V, and component tolerances allow operation within ±10% of those nominal values without derating. Once energized, the power electronics can support motor output up to 200 kW. This capacity suits conveyors, process lines, mixers, and other heavy-duty applications that need steady torque across a wide speed range and dependable speed regulation under varying load conditions.
A built-in brake chopper dissipates regenerated energy during deceleration and helps control DC-bus voltage when the motor is driven by an overrunning load. Temperature rise is limited by forced-air cooling with integrated liquid circulation, which combines airflow and internal coolant channels to remove heat from the power section during sustained operation. Line-side disturbances are reduced by an integrated mains filter, while the control electronics remain available through 24 V standby power supplied externally when the main supply is off. This arrangement allows the control section to remain active for monitoring and control readiness without requiring the main power stage to stay energized.
