Product Description:
The RD52.1-4B-011-L-NN-NN-NN-FW is a Bosch Rexroth Indramat unit from the RD 500 Drive Controllers series. Engineered for industrial automation, the controller converts three-phase mains power into regulated motor voltage and current so that induction or synchronous motors can be driven with precise torque and speed. Installed inside a control cabinet, it coordinates motion sequences, reports status data to higher-level PLCs, and protects connected machinery from electrical faults. This makes it suitable for applications that need repeatable acceleration, controlled deceleration, and dependable feedback to the main control system. Typical uses include conveyor lines, metal-forming equipment, and packaging stations where dynamic drive response and stable speed regulation are required during changing load conditions.
For its input source, the drive expects a three-phase AC supply and tolerates line levels between 380 to 480 V. A permissible deviation of ±10% allows continuous operation during common plant voltage swings without interrupting normal motor control. Motor regulation is handled by field-oriented vector control, an algorithm that separates flux and torque components to improve low-speed accuracy, startup smoothness, and transient response. Excess kinetic energy during deceleration is routed to the internal resistor through the built-in brake chopper, shortening stop times and helping the drive manage regenerated energy during frequent speed changes.
Thermal stability is maintained with forced-air cooling; axial fans push air across heat sinks to keep semiconductor junctions within rated limits during continuous duty. An integrated mains filter suppresses conducted emissions, enabling installation on networks sensitive to electromagnetic interference and helping reduce noise returned to the supply. The option card slots are not equipped, so the controller ships in its base configuration without additional application-specific functions. The controller is classified as design generation 1, indicating an early hardware revision within the RD 500 platform.
