The R-MOD ET EtherCAT Stepper Motor and Drive Combo Unit combines a stepper motor, digital drive, multi-turn absolute encoder and EtherCAT communication interface within a single compact assembly.

Integrating the motor and drive reduces control-panel space, simplifies machine wiring and allows the motion controller to be positioned close to the driven axis. This makes the R-MOD ET particularly suitable for decentralised and distributed automation architectures.

The multi-turn absolute encoder retains axis position information without requiring a homing routine after each power cycle. Closed-loop position control provides reliable positioning performance while monitoring the motor’s actual movement.

The range operates from a 24–48 V DC supply and is available with 56 mm and 60 mm motor flanges. Four motor configurations provide holding torques from 110 Ncm to 300 Ncm, allowing the required size and torque to be matched to the application.

EtherCAT communication supports integration into high-performance, synchronised motion systems. Industrial M12 and M8 connectors provide robust connections, while integrated Safe Torque Off helps support machine safety requirements.

Typical Applications

• Distributed machine automation
• Packaging and labelling equipment
• Assembly machinery
• Materials handling systems
• Pick-and-place equipment
• Printing and converting machinery
• Multi-axis EtherCAT systems
• Space-constrained machine designs

The HI-MOD ET/ETS EtherCAT Stepper Motor and Drive Combo Unit integrates a stepper motor, bipolar chopper drive, battery-less multi-turn absolute encoder and EtherCAT communication interface within a single compact assembly.

Its full closed-loop control system continuously monitors the motor’s actual position, providing reliable positioning and improved performance under changing load conditions. The absolute encoder retains position information without batteries and removes the need to repeat the homing process after every power cycle.

The HI-MOD range provides holding torque up to 920 Ncm and supports supply voltages from 48 to 140 V DC. Higher-voltage operation helps improve torque availability at medium and high motor speeds for demanding dynamic applications.

HI-MOD ET models provide EtherCAT motion control without integrated Safe Torque Off. HI-MOD ETS versions add a SIL3-rated Safe Torque Off function with Error Detection Monitor for applications requiring an integrated machine safety function.

M12 connectors provide robust industrial connections for power, EtherCAT and digital I/O. Additional features include multiple operating modes, two digital inputs, two digital outputs, a touch-probe hardware input and RTA’s Auto-Sync function.

Front brake and planetary gearbox options are also available, allowing the integrated unit to be configured for vertical axes, increased torque or reduced output speed.

Typical Applications

• Distributed machine automation
• Packaging and labelling machinery
• Assembly equipment
• Materials handling systems
• Vertical positioning axes
• Printing and converting machinery
• Multi-axis EtherCAT systems
• High-torque positioning applications
