RS51.1-4G-006-L-V1-FW

The RS51.1-4G-006-L-V1-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers drive unit offers a high-performance solution for industrial motor control applications. It accepts a nominal connecting voltage of 380 to 480 V AC with a tolerance of ±10%, delivering precise regulation across the specified voltage range. The on-board built-in brake chopper and resistor efficiently manages regenerative energy during rapid deceleration or emergency stops, while a 24V standby power circuit maintains critical logic and communication channels. Designed with modular connectivity, this controller supports plug-in expansions for fieldbus interfaces and sensor integration without hardware modification.

Delivering a continuous rated power of 6kVA and a peak output capacity of 7.5kVA, the unit accommodates transient loads up to 125% of its nominal current. It provides a maximum current of 13A and a nominal current of 8A, enabling flexible scaling for diverse motor sizes. The forced air cooling system sustains optimal thermal management throughout the full 0 to 2000Hz output frequency range while operating within ambient temperatures from 0 °C to 40 °C. Encased in an IP20 enclosure, the controller ensures protection against solid objects and dust ingress, and it incorporates grounding terminals for secure chassis bonding and enhanced EMC immunity.

Seamless integration with Bosch Rexroth Indramat’s ecosystem enables real-time diagnostics, predictive maintenance, and synchronized multi-axis coordination. The robust construction, adherence to EMC standards, and vertical-mount design guarantee reliable operation even in harsh production environments. Ideal for machine tools, conveyors, robotic cells, and packaging lines, the RS51.1-4G-006-L-V1-FW delivers precise speed control, dynamic torque response, and reduced downtime for high-throughput manufacturing.
