RZW01.1-055-NNN

RZW01.1-055-NNN, Bosch Rexroth Indramat, RZW Braking Resistors model delivers high-performance braking energy dissipation in industrial automation environments. Weighing just 3.5 kg, it integrates seamlessly into compact drive cabinets without adding undue mass. It accommodates a broad 24V DC to 48V DC input range to support diverse drive topologies, from low-voltage conveyors to mid-range servo systems. Engineered to protect sensitive power stages, it reduces thermal stress and guards against system downtime caused by braking-induced overvoltage.

This resistor supports a continuous current rating of 40A and endures peak currents up to 73A to absorb sudden energy surges without compromising structural integrity. Its Natural convection cooling architecture eliminates moving parts, reducing maintenance intervals in dusty or oil-mist environments. An integrated incremental encoder with Hall sensors provides real-time mechanical feedback to drive controllers, enabling adaptive braking profiles and fault detection. Dual communication interfaces via RS232 and RS485 facilitate remote parameterization, status monitoring, and integration into PLC or SCADA systems. Certified to protection class IP20 and suited for rotational speeds up to 7500 rpm, the compact 3.5 kg housing balances thermal performance and space efficiency in multi-axis machine designs.

Engineered for seamless pairing with RD 500 Bosch Rexroth drive systems, the RZW01.1-055-NNN simplifies commissioning and drive performance tuning through plug-and-play configuration. Its robust ceramic insulation provides exceptional dielectric strength and thermal resilience, ensuring stable operation under fluctuating ambient conditions. Ideal for dynamic braking applications across packaging, material handling, and gantry systems, it optimizes energy management while reducing thermal stress on critical components, thereby extending overall system service life.
