SM50-100LN by Bosch Rexroth Indramat

The SM50-100LN servo module from Bosch Rexroth Indramat is a robust addition to the SM AC Inverters series, engineered for demanding industrial automation environments. This Product Type features a Construction transistor system and delivers a Rated Current of 50 A with a Peak Current capacity of 100 A for dynamic acceleration and precision control. The module operates on a DC Link Voltage Range of 460–700 V, accommodating diverse high-voltage platforms. Thermal management is achieved through Cooling Method forced ventilation driven by a Ventilator Supply of 24 V DC, 100 mA, ensuring consistent performance under continuous operation. Compact yet powerful, the SM50-100LN balances high output with streamlined integration into automation cabinets.

Performance is optimized by a Speed Regulation Ratio exceeding 1:10,000, enabling fine-grained speed and torque adjustments across a wide dynamic range. The device handles up to Max Power Loss of 350 W through its efficient cooling system without compromising reliability. When ambient temperatures exceed Operating Temperature thresholds, the module applies a Current Derating Above 45 °C of 1.2% per K to protect internal components. It maintains functionality from 0 °C to +55 °C and can be stored between -25 °C and +70 °C, preserving readiness and reducing downtime. The integrated transistor architecture supports rapid response times and stable output, making the servo module ideal for high-speed machining and robotics.

Designed for seamless integration, the SM50-100LN holds an Ingress Protection rating of IP00 (DIN 40050, IEC 144) and meets Insulation Class F (DIN 40040) standards, requiring installation in enclosed cabinets for maximum safety. It withstands altitudes up to Max Operating Altitude of 1000 m amsl, maintaining reliable operation in varied plant topographies. The module’s compact footprint and standardized interfaces simplify integration with PLCs, CNC controls, and safety systems. With proven performance in industrial automation, packaging, material handling, and precision assembly, the SM50-100LN delivers dependable motion control in challenging production environments.
