Technical Specifications

Main Features and Advantages

Integrated functional safety for collaborative environments: The REXROTH DKC10.3-018-3-MGP-01VRS includes certified safety functions STO and SS1, eliminating the need for external safety relays in many applications. This reduces wiring complexity and panel space while ensuring rapid, reliable motor shutdown during emergency stops or access events—critical for human-machine collaboration in assembly cells or palletizing stations.

Compact, fanless design with high power density: Despite its small form factor (only 100 mm wide), the REXROTH DKC10.3-018-3-MGP-01VRS delivers robust performance without requiring forced air cooling. The absence of fans enhances reliability by removing moving parts prone to dust clogging or mechanical wear, making it ideal for food processing, pharmaceuticals, and cleanroom environments where contamination must be minimized.

Flexible communication and easy commissioning: The REXROTH DKC10.3-018-3-MGP-01VRS supports fieldbus independence through interchangeable communication modules. Whether your plant uses EtherCAT for high-speed synchronization or PROFINET for TIA Portal integration, this drive adapts without hardware changes. Commissioning is accelerated via auto-tuning algorithms and guided setup in IndraWorks, reducing engineering time and startup risk.

Built-in brake management and energy efficiency: Equipped with an internal brake chopper, the REXROTH DKC10.3-018-3-MGP-01VRS safely dissipates regenerative energy from decelerating loads—essential for vertical axes like lifters or robotic arms. Combined with efficient power conversion (>95%), it minimizes energy waste and thermal load in densely packed cabinets, contributing to lower total cost of ownership.

Application Field

The REXROTH DKC10.3-018-3-MGP-01VRS excels in applications requiring precise, responsive, and safe motion control across discrete and process industries. In packaging machinery—such as carton erectors, case packers, and labeling systems—the drive’s fast response and high bandwidth enable accurate registration and high cycle rates, even under variable load conditions. The integrated STO function allows safe access during jam clearing without full line shutdown, improving operational efficiency.

In robotics and automated guided vehicles (AGVs), the REXROTH DKC10.3-018-3-MGP-01VRS powers joint axes or traction drives where compactness and reliability are critical. Its support for EtherCAT enables tight multi-axis synchronization for path accuracy, while the fanless design ensures trouble-free operation in dusty warehouse environments. Similarly, in printing and converting equipment, the REXROTH DKC10.3-018-3-MGP-01VRS maintains web tension and register control through high-resolution feedback and low-latency current loops. Across all these sectors, the REXROTH DKC10.3-018-3-MGP-01VRS provides a balanced combination of performance, safety, and serviceability that meets the evolving demands of smart manufacturing.

Installation and Maintenance

Pre-installation preparation: Before installing the REXROTH DKC10.3-018-3-MGP-01VRS, verify that the mains supply matches the 3-phase 400 V specification and that proper grounding is established per IEC 60204-1. Ensure adequate spacing (minimum 20 mm above and below) for natural convection cooling. Mount the drive vertically on a DIN rail or directly to a backplate using the provided brackets. Connect motor, encoder, and brake lines according to the terminal labeling, observing polarity and shielding best practices. If using a communication module, insert it firmly into the side slot before powering up.

Maintenance recommendations: The REXROTH DKC10.3-018-3-MGP-01VRS requires minimal routine maintenance due to its fanless, solid-state design. Periodically inspect terminal tightness and check for dust accumulation on the heatsink fins—clean gently with dry compressed air if needed. Monitor the status LEDs: green indicates normal operation, while red signals overtemperature, overcurrent, or safety faults. Use IndraWorks to read detailed error logs and perform predictive checks on DC bus capacitors. When replacing a failed REXROTH DKC10.3-018-3-MGP-01VRS, transfer parameter backups via SD card or software to ensure seamless restart without re-engineering.
