Beckhoff Enhances MDR Controllers for Modular Conveyors
New EtherCAT-based motor-driven roller controllers integrate safety and flexible motor control to improve efficiency and reduce wiring in intralogistics systems.

The new EP741x MDR controllers take the safety, efficiency, and modularity of automated material flow solutions to a new level.
Intralogistics, e-commerce distribution, and automated material handling systems require scalable and synchronised conveyor solutions to manage increasing throughput demands. Beckhoff Automation has introduced the EP741x MDR controller series, designed to improve control performance, modularity, and safety in motor-driven roller (MDR) conveyor systems.
EtherCAT Integration Enables High-Speed Synchronisation
The EP741x controllers integrate EtherCAT communication, enabling update rates in the sub-millisecond range. This allows precise synchronisation of conveyor zones and routing logic, even in large-scale systems with complex layouts.
Traditional bus systems can limit the responsiveness of MDR conveyors, particularly in zone-based operation. By contrast, EtherCAT-based communication supports real-time coordination between conveyor segments, improving throughput and reducing bottlenecks in automated material flow systems.
Flexible Motor Control Simplifies System Design
The controllers provide sensorless control of brushless DC (BLDC) motors in the 24 V to 48 V range. A key design feature is compatibility with motor rollers from multiple manufacturers, allowing system integrators to select components independently of the control hardware.
This flexibility reduces engineering constraints and simplifies spare parts management by avoiding vendor-specific dependencies. The product range includes 2-channel (EP7412) and 4-channel (EP7414) variants, enabling adaptation to different conveyor configurations.
Modular Design Reduces Wiring and Installation Effort
Built on the EtherCAT Box architecture, the EP741x modules feature a fully cascadable design with integrated connection cables and standard M8 or M12 connectors. The IP54-rated housing supports installation directly on conveyor systems, including mounting within conveyor rail profiles.
This approach reduces wiring complexity, minimises installation errors, and shortens commissioning time. The compact design also supports space-constrained installations typical in high-density intralogistics environments.
Integrated Safety Function Enables Decentralised Protection
An optional version of the controller introduces Safe Torque Off (STO) functionality via Safety over EtherCAT (FSoE). Unlike conventional systems that require complete power shutdown during emergency stops, this design disconnects the motor power stage while maintaining logic-level control.
This allows the system to remain operational at the control level while ensuring safe conditions at the drive level. The decentralised safety architecture enables the creation of independently controlled safety zones, reducing the need for additional safety hardware and complex wiring.
For applications with lower safety requirements, Beckhoff also offers variants without integrated safety functions, providing a cost-optimised alternative.
Comparison with Conventional MDR Control Solutions
Conventional MDR controllers often rely on centralised control architectures and proprietary motor compatibility, which can limit scalability and increase system complexity. Additionally, safety functions typically require external components and full system shutdown during emergency events.
In contrast, the EP741x series combines real-time EtherCAT communication, multi-vendor motor compatibility, and optional integrated safety in a distributed architecture. This enables more flexible system design, improved operational continuity, and reduced installation effort.
By integrating high-speed communication, modular hardware design, and decentralised safety, the EP741x MDR controllers address key challenges in modern intralogistics systems, where scalability, reliability, and efficiency are critical.
