RD52.1-4B-022-L-NN-FW

The Bosch Rexroth Indramat RD52.1-4B-022-L-NN-FW is a high-performance drive controller from the RD 500 Drive Controllers series designed for industrial motion control applications. This AC drive converter features a Nominal Connecting Voltage of 3 x AC 380-480 V and a Rated Power of 22 kW, delivering reliable power for automated systems. Its forced air cooling mechanism ensures consistent thermal management under continuous operation. The primary function of the RD52.1-4B-022-L-NN-FW is to provide field-oriented regulation, enabling precise speed and torque control in a wide range of manufacturing processes.

The RD52.1-4B-022-L-NN-FW excels in technical versatility, offering protection in an IP20 enclosure that meets 3K3 environmental specifications for dust and moisture resistance. It draws 43 A of rated current during continuous operation and can withstand overloads of 55 A for 60 seconds. Short-term overload capacity reaches 72 A at 170% load for 1 second and 85 A at 200% load for 0.5 seconds, ensuring the controller handles transient demands. A user-friendly control panel with an integrated LCD display simplifies configuration, monitoring, and maintenance. The built-in brake chopper supports continuous regenerative braking at 14 kW with a minimum resistance of 11.7 Ohm, and a peak braking power of 56 kW for 1 second.

Built for compatibility and efficiency, the RD52.1-4B-022-L-NN-FW supports firmware updates that enhance operational control and system reliability. Standard-sized cables are recommended for optimal signal integrity, and the forced air cooling fan must be positioned away from heat-sensitive components to maintain performance. Complete documentation, including a user manual and warranty policy, is provided, with warranty validity dependent on the use of approved devices. In industrial environments, this converter offers robust durability, streamlined commissioning, and improved energy efficiency, making it an ideal solution for automated drive systems seeking precise, reliable motion control.
