Product Description:
Bosch Rexroth Indramat’s RD52.1-8N-045-L-V1-FW belongs to the RD 500 Drive Controllers series and is specified for variable-speed operation of three-phase motors in automated machinery. The unit functions as a drive controller that converts regulated DC energy into a commanded AC waveform. This allows motion axes to accelerate, hold a set speed, or decelerate under closed-loop control within process lines, packaging equipment, and material-handling cells.
The controller delivers a rated output of 45 kW, a power level suited for mid-range pumps, blowers, and conveyor drives. Its DC link accepts up to 700 V, allowing the inverter stage to synthesize high peak phase voltages while maintaining a compact bus capacitor. Regulation is handled by field-oriented vector control, which separates torque-producing and magnetizing currents so dynamic speed or position loops can be tuned with minimal steady-state error. Thermal energy is removed through forced air cooling; an internal fan drives cabinet air across the heat sink to keep semiconductor junction temperatures within limits and prevent derating at typical plant ambient conditions. For applications that dissipate kinetic energy, an external braking resistor can be added because the unit is supplied without a built-in brake chopper.
The DC bus is sourced from an inverter DC supply, so the controller is integrated downstream of a rectifier module rather than tied directly to the three-phase line. Control electronics remain powered during mains outages by an auxiliary feed that provides 24 V standby power, letting fieldbuses, encoders, and stored drive parameters remain active while the main converter is de-energized. Hardware details correspond to Design Generation 1, which matches first-generation RD 500 option cards. The operating software must be ordered as a separate subposition.
