RD52.1-7N-015-L-NN-FW

The Bosch Rexroth Indramat RD52.1-7N-015-L-NN-FW from the RD 500 Drive Controllers series is a robust DC supply inverter designed for demanding industrial applications. This inverter without a built-in brake chopper operates on a nominal connecting voltage of DC 530-670 V and delivers a rated power of 15 kW. The unit’s forced air cooling mode ensures efficient heat dissipation, supported by a minimum airflow requirement of 0.05 m³/s. With a compact size class B profile and a weight of 11.3 kg, it balances high performance with manageable installation demands.

The RD52.1-7N-015-L-NN-FW can be configured to run at four selectable pulse frequencies—notably at 4 kHz, 8 kHz, and 12 kHz—altering its output characteristics for different motor requirements. At 4 kHz, the drive supplies a rated current of 30 A and sustains the full 15 kW output, while at 8 kHz it produces 11 kW at 25 A, and at 12 kHz it provides 18 A for precision applications. Encased in an IP20 enclosure conforming to EN 60529 and classified in environmental category 3K3, it withstands typical factory conditions across a 0 to 40 °C ambient temperature range. The inverter’s design also accommodates accessory cooling options, though this model comes standard with the forced air system.

Commissioning the RD52.1-7N-015-L-NN-FW requires separate firmware ordering to match specific feature sets, ensuring tailored functionality for each machine. Installation and integration into motion control setups should be performed by trained personnel to maintain safety and performance integrity. Backed by a one-year warranty from Wake Industrial, this drive controller offers reliable operation and flexible configurability for a wide range of automation and drive tasks.
