RR52.1-7N-003-P-V1-FW

The Bosch Rexroth Indramat RR52.1-7N-003-P-V1-FW from the RD 500 Drive Controllers series by Bosch Rexroth Indramat provides precision DC supply inversion with a 2.2 kW motor output and a variable 0-500 Hz output frequency. This unit operates as an inverter without a built-in brake chopper and features a robust heat conducting plate for effective thermal management. A pulse frequency of 4 kHz ensures low-harmonic switching, while the absence of a line filter and input throttle reduces component count. The control must be mounted in a vertical orientation by qualified personnel to preserve the integrity of its electrostatically sensitive components.

Reliability is enhanced through a double overload capability of 0.5 seconds and a protected discharge path that limits residual voltage with a discharge current over 3.5 mA per DIN VDE 0160. The device supports a 24 V standby power supply and high-voltage operation, with a protective conductor requiring a minimum 10 mm² cross-section. The modular design, including a size code of A and compact dimensions of 445 x 90 mm, simplifies installation in control cabinets or closed housings. Sufficient ventilation around the rear-cooled power section is essential to maintain performance at up to 55 °C ambient temperature.

Maintenance is streamlined by the unit’s standardized form factor and global shipping support, backed by a comprehensive one-year warranty. With a rated output current of 4.9 A and a dedicated rear-cooling heat dissipation panel, the RR52.1-7N-003-P-V1-FW offers dependable operation in demanding textile engineering and industrial automation environments.
