DM 45K 6311-D

The Bosch Rexroth Indramat DM 45K 6311-D drive is part of the Servodyn-D series, designed for precise motion control in industrial automation systems. This DM Servo Drive operates at an input voltage of 670V and features a high-resolution Resolver encoder for accurate position feedback. Equipped with a PROFIBUS-DP interface, this drive ensures seamless integration into distributed control architectures and real-time data exchange. Its primary function is to regulate and control the speed and torque of synchronous and asynchronous motors in demanding production environments.

In detailed operation, the DM 45K 6311-D utilizes a regulated DC 670V supply (or up to DC 715V with non-regulated input) derived from a three-phase AC power source. It employs a digital closed-loop control algorithm to maintain precise one-axis positioning and dynamic response. The built-in 12-bit Resolver encoder delivers high accuracy in actual position values, while the PROFIBUS-DP interface supports multi-drop communication and high-speed data throughput. Natural convection cooling manages a maximum power loss of 205W in the three-phase module, ensuring stable performance without auxiliary fans.

Designed for robust industrial use, the DM 45K 6311-D features an IP20 protection class and can be installed up to 1000 meters above sea level (derated to 3000 meters), making it suitable for diverse factory environments. Weighing approximately 6.7 kg, it balances compactness with durability. The drive’s compatibility with standard 24V control supplies and its global shipping options, backed by a one-year warranty, underscore its reliability and serviceability. By delivering precise control, high integration flexibility, and rugged construction, this servo drive enhances operational efficiency and reduces downtime in modern automated production lines.
