RD52.1-7N-075-L-V1-FW

The RD52.1-7N-075-L-V1-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers delivers a high-performance DC supply inverter designed for demanding industrial automation. The controller features a nominal connecting voltage of DC 530-670 V and a Rated Power of 75 kW, providing robust energy conversion matched to large servo motors. Equipped with a 32-bit signal processor, it handles complex motion profiles with precision and supports a 24 V standby power supply for continuous control retention. The module’s protection class of IP20 ensures safe operation in standard manufacturing environments.

Using forced air cooling, the unit dissipates heat effectively to maintain optimal internal temperatures even under peak loads. The converter integrates a flux vector control (FVC) algorithm that separates stator current into magnetization and torque-producing components, maximizing motor efficiency. A nominal tolerance of <±10%> on the DC link voltage secures stable performance across the <530–670 V> range, while radio interference suppression rated A1 meets industrial EMC standards. Environmental class 3k3 allows operation in moderate dust and moisture conditions, and the inverter’s compact dimensions of 380 x 320 x 405 mm combined with a weight of 38 kg simplify cabinet integration. The drive delivers a Rated Current of 135 A, with short‐term overload capacities of 230 A for 1 s and 270 A for 0.5 s to absorb transient torque spikes. The module ships without a built-in brake chopper, offering design flexibility in brake resistor selection.

Engineers trust the RD52.1-7N-075-L-V1-FW for seamless integration into multi-axis systems, leveraging its open interface and standardized control protocols. Its robust construction and forced-air cooling guarantee high reliability and long service life, minimizing unplanned downtime. Ideal for applications in material handling, automotive assembly, and heavy-duty packaging lines, the drive controller delivers precise torque and speed control where performance and uptime are critical.
