The B&R 7DM465 is a high-performance single-axis servo drive designed for precision motion tasks in modular automation systems. Part of B&R’s X20 series, this drive integrates seamlessly with Powerlink and EtherCAT P real-time networks to deliver nanosecond-level synchronization in multi-axis applications. The B&R 7DM465 supports 650W continuous power output (1.2kW peak) and features advanced Space Vector Modulation (SVM) technology for ultra-smooth torque control. Its compact 32mm width minimizes cabinet space while supporting motors up to 3A RMS, with built-in safety functions (STO, SS1) certified to SIL 3/PLe. Engineered for flexibility, it accepts incremental/absolute encoders (Endat 2.2, BiSS-C, Hiperface DSL) and includes SynchroLink interfaces for daisy-chaining drives without additional switches.
Optimized for rapid deployment, the B&R 7DM465 leverages B&R’s Automation Studio engineering environment for centralized parameterization and diagnostics. Regenerative energy handling eliminates external resistors in most applications, while the drive’s -25°C to +60°C operating range ensures reliability in harsh industrial environments like plastics extrusion or automated warehousing.
