The B&R 50LS03.1000-00 is a high-performance, compact servo drive within the ACOPOS P3 family from B&R Industrial Automation—now fully integrated into ABB’s automation portfolio under the ABB Ability™ ecosystem. Designed for demanding multi-axis applications in packaging, robotics, printing, and machine tooling, the B&R 50LS03.1000-00 delivers precise motion control across three independent motor axes from a single, space-saving unit. Operating from a 400–480 VAC supply, it provides up to 3 kW continuous output per axis (with peak capabilities higher), enabling rapid acceleration, tight synchronization, and energy-efficient operation through shared DC bus technology.
As part of B&R’s modular ACOPOS P3 platform, the B&R 50LS03.1000-00 leverages real-time Ethernet POWERLINK for deterministic communication with the central controller (e.g., X20 or APC systems), achieving cycle times as low as 400 µs. It supports a wide range of feedback systems—including EnDat 2.2, Hiperface, BiSS C, and incremental encoders—and automatically identifies motor parameters for quick commissioning via Automation Studio. Critically, the B&R 50LS03.1000-00 integrates certified safety functions such as Safe Torque Off (STO) and Safe Stop 1 (SS1) per IEC 61800-5-2 and ISO 13849 (up to PL e / SIL 3), making it suitable for collaborative robotics and human-machine interfaces where functional safety is non-negotiable. Its robust design, diagnostic depth, and scalability position it as a cornerstone of modern, flexible production lines seeking both agility and reliability.

Main Features and Advantages
Three-axis integration in a single compact footprint
The B&R 50LS03.1000-00 eliminates the need for three separate drives by consolidating control of up to three servo motors into one housing. This reduces cabinet size by up to 40%, simplifies wiring, and lowers total cost of ownership—ideal for space-constrained machines like cartoners, delta robots, or small CNC routers.
Shared DC bus for regenerative energy efficiency
Unlike standalone inverters that dissipate braking energy as heat, the B&R 50LS03.1000-00 features an integrated DC bus that allows kinetic energy from decelerating axes to be reused by accelerating ones. In cyclic applications (e.g., pick-and-place), this can reduce net energy consumption by 15–30% and minimize heat buildup in control panels.
Native support for advanced feedback and motor types
The B&R 50LS03.1000-00 auto-detects connected motors and encoders during startup, supporting both synchronous (permanent magnet) and asynchronous (induction) servos. With full compatibility for absolute encoders like EnDat 2.2, it enables “zero-position” startup without homing—critical for food packaging lines requiring hygiene-compliant, no-contact initialization.
Integrated functional safety without external modules
Safety is built directly into the power stage of the B&R 50LS03.1000-00, with dual-channel STO circuits that cut torque-generating current within milliseconds. This eliminates the need for external safety relays or contactors, reducing component count while meeting the highest safety integrity levels for collaborative automation.
Comprehensive diagnostics and remote maintenance
Via Automation Studio, users can monitor real-time current, temperature, and error logs for each axis. The B&R 50LS03.1000-00 also supports predictive maintenance through vibration analysis (when paired with compatible motors) and lifetime tracking of power semiconductors—enabling proactive service before failures occur.
Application Field
The B&R 50LS03.1000-00 is widely deployed in industries requiring synchronized, high-speed motion with minimal footprint and maximum uptime. In flexible packaging lines—such as vertical form-fill-seal (VFFS) or horizontal flow wrappers—the B&R 50LS03.1000-00 controls film feed, sealing jaws, and product indexing axes with micron-level precision, adapting instantly to format changes via recipe management. Its ability to synchronize multiple axes over POWERLINK ensures consistent package quality at speeds exceeding 200 cycles per minute.
In industrial robotics, particularly SCARA and delta configurations used in electronics assembly or pharmaceutical handling, the B&R 50LS03.1000-00 enables smooth path interpolation and rapid direction changes while maintaining safety compliance through integrated STO. Similarly, in digital printing and converting machinery, it drives unwind/rewind tension control, web guiding, and print cylinder registration—all coordinated to prevent material stretch or misregistration.
The B&R 50LS03.1000-00 also serves in machine tool auxiliary systems, such as automatic tool changers, pallet shuttles, and coolant pumps, where reliability and fast response are essential. Because it seamlessly integrates into ABB’s broader automation architecture—including ABB robots and process controllers—it is increasingly specified in smart factories pursuing unified engineering, data transparency, and predictive maintenance under the ABB Ability™ platform.

Installation and Maintenance
Pre-installation preparation: Before mounting the B&R 50LS03.1000-00, ensure adequate ventilation with minimum 50 mm clearance above and below for convection cooling. Verify that the 480 VAC supply includes proper fusing and meets harmonic distortion limits. Use shielded, twisted-pair cables for motor and encoder connections, grounding shields at the drive end only. Confirm that all safety circuits (STO inputs) are wired per ISO 13849 Category 3/4 requirements using dual-channel architecture. Perform a dry-run communication test with the POWERLINK master before energizing motors.
Maintenance recommendations: Schedule biannual inspections of the B&R 50LS03.1000-00 to clean dust from heat sinks using dry, oil-free compressed air (<30 PSI). Check terminal tightness on power and motor connectors (torque to 1.2 Nm). Monitor internal temperature and DC bus voltage trends via Automation Studio to detect early signs of capacitor aging or cooling degradation. If an axis exhibits jitter or overheating, validate motor insulation resistance and encoder cable integrity. Replace the B&R 50LS03.1000-00 if error logs indicate repeated overvoltage or I²t overload events—do not attempt internal repair. Keep a tested spare unit on-site to minimize MTTR in high-availability production environments.
