3. Core Features
  • Decentralized Near-motor Design

    Installed close to the servo motor, reduces cabinet wiring, saves control cabinet space and lowers system wiring costs.

  • IP65 High Protection

    Dust-tight and splash-proof, suitable for workshop, production line and harsh industrial on-site environments.

  • EtherCAT High-speed Bus Communication

    Supports real-time EtherCAT protocol, fast data transmission, strong anti-interference, perfect for multi-axis linkage and high-precision motion control.

  • 18A High Current Output

    Strong overload capacity, stable operation under frequent start-stop and variable load conditions.

  • 750V DC Bus Voltage

    Matches Rexroth standard DC bus system, good compatibility with the whole IndraDrive MI series.

  • Natural Convection Cooling

    No extra fan required, low noise, low failure rate and easy maintenance.

  • High-precision Closed-loop Control

    Cooperates with Rexroth servo motors to realize accurate speed, position and torque control.

  • Easy Installation & Expansion

    Supports daisy-chain connection via hybrid cables, convenient for multi-axis system expansion and on-site debugging.

5. Product Description

The Rexroth KMS02.1B-A018-P-D7-ET is a high-performance decentralized near-motor servo drive belonging to the Rexroth IndraDrive MI series, specially developed for high-precision motion control scenarios in industrial automation.

Adopting a decentralized installation concept, this drive is mounted near the servo motor instead of inside the control cabinet. It greatly simplifies complex cabinet wiring, reduces signal interference, and optimizes the overall layout of automation equipment. With IP65 protection level, it can work stably in dusty and splash-prone industrial workshops and production lines.

Equipped with standard EtherCAT communication, it ensures ultra-fast real-time data interaction between the drive and upper PLC or motion controller, which is ideal for multi-axis synchronous control. The design with 18A maximum current and 750V DC bus provides strong power output and excellent load adaptability, supporting frequent acceleration, deceleration and positioning actions.

Using natural convection cooling without a built-in fan, the product features low noise, high reliability and low maintenance cost. It is widely matched with Rexroth synchronous servo motors, forming a complete high-precision servo system, and is the preferred drive component for medium and high-end automation equipment.

6. Application Fields
  • High-precision automated assembly lines
  • Packaging machinery, labeling machines and filling equipment
  • Material handling, conveyor systems and logistics automation
  • CNC machine tools, processing equipment and robotic arms
  • Textile, printing, plastics and rubber industrial machinery
  • Multi-axis linkage automation equipment
  • All scenarios requiring EtherCAT high-speed communication and precision motion control
