RD42.1-5R-026-L

RD42.1-5R-026-L, Bosch Rexroth Indramat, RD 500 Drive Controllers delivers a robust 26 kW power stage at 3-phase AC 400 V with a rated current of 50 A. This module features a regenerative device variant and advanced drive logic to regulate and recover braking energy in high-performance production lines. Engineered with forced air cooling, it maintains optimal operating temperatures under continuous load and supports a 32-bit floating-point signal processor for precision control. Compliance with both American and European standards ensures consistent performance in global installations.

Detailed specifications include a wide supply voltage window of 530 to 670 V and an ambient temperature range from 0 to 40 °C, with storage tolerance up to 75 °C. The controller’s leakage current is limited to 3.5 mA, requiring secure grounding for safety. Connectivity is extensive: built-in interfaces support SERCOS, Profibus DP, Interbus S, CAN bus, and RS-232 communications for seamless integration into diverse automation networks. The compact electro-mechanical design prioritizes reliability, with metal-rich construction for enhanced durability and recyclability.

Integration into machine control architectures is straightforward thanks to flexible parameterisation via standard industrial buses and front-end access to diagnostic data. The regenerative variant’s energy feedback capability lowers overall system power consumption and heat generation, improving plant efficiency and reducing cooling requirements. Ideal for packaging, material handling, and processing machinery, the RD42.1-5R-026-L drive controller combines precision, robustness, and serviceability in a global one-year-warranty package.
