High-Accuracy DRIVE‑CLiQ Encoder for CNC Machine Tools

The Magnescale RU97 is a high-performance absolute rotary encoder designed for precision CNC machine tool applications, delivering accurate and reliable rotation position feedback via Siemens DRIVE‑CLiQ communication.

Built with a robust magnetic sensing system, the RU97 operates reliably in harsh industrial environments, including exposure to oil, condensation, and vibration, making it ideal for demanding machining conditions.

Key features

High‑accuracy angular positioning – Provides ±2.5 arcsecond accuracy for precise rotary feedback
Ultra‑high resolution output – Up to 25‑bit resolution (33,554,432 pulses per revolution)
Compact enclosed design – Robust housing protects internal components while enabling easy integration
Resistant to harsh environments – Magnetic system ensures reliable operation in oil, coolant and condensation
Flexible mounting with internal coupling – Simplifies installation and accommodates alignment tolerances
Direct CNC integration (SIEMENS) – Supports DRIVE‑CLiQ communication for seamless integration into SIEMENS control systems

How the RU97 Absolute Encoder works

The RU97 uses a single-turn absolute magnetic measurement system, which determines the shaft position without requiring a reference or homing cycle.

Outputs absolute position data on startup
Maintains position accuracy even after power loss
Uses a serial DRIVE‑CLiQ signal interface for real-time communication

This makes it ideal for modern high-performance CNC machines requiring consistent and reliable positioning feedback.

Compatible Systems

The RU97 is designed primarily for:

SIEMENS DRIVE‑CLiQ systems

Output is provided via absolute serial communication, removing the need for additional signal processing hardware.

Designed for CNC Machine Tool Applications

CNC rotary axes and indexing systems
Precision machine tool spindles
Compact rotary positioning systems
Automated production equipment
Applications requiring high resolution in limited space

Why choose the RU97

Combines compact size with extremely high resolution
Designed for harsh industrial conditions
Simplifies system integration with direct DRIVE‑CLiQ output
Ideal for high‑precision rotary applications with limited space

Compared to traditional optical or incremental encoders, the RU97 offers key advantages:

RU97 Absolute Encoder	Conventional Encoders
Absolute position on startup	Requires homing
Resistant to oil and contamination	Sensitive to dirt and coolant
Non-optical magnetic system	Optical components prone to failure
Reliable in harsh environments	Requires cleaner operating conditions

The magnetic system ensures consistent performance in real-world CNC environments where contamination is unavoidable.
