The Siemens DRIVE-CLiQ is an innovative and powerful communication interface for connecting gratings and direct measuring systems to SINUMERIK and SINAMICS drive components. RESOLUTE's true absolute encoders feature the DRIVE-CLiQ interface to help machine builders achieve higher performance and greater reliability. The product is positionable immediately after opening, making it ideal for high-performance lathe spindles and direct-drive rotary (DDR) torque motors that require the highest levels of precision and motion control.
RESOLUTE DRIVE-CLiQ has excellent motion control performance. RESOLUTE's unique working principle is similar to that of ultra-high-speed digital cameras. When capturing scale images, even with motion speeds of up to 100 m/s (up to 36 000 rpm on a circular grating), the resolution can reach 1 nm (in a circular grating). Up to 32 bits). The advanced optical system means that the detection mode itself has ultra-low electronic subdivision error (SDE) and extremely low noise (jitter) characteristics, so users can benefit from lower speed ripple and superior position stability. .

Typically, such grating products with high fidelity motion control are very susceptible to damage, but RESOLUTE uses a sealed readhead and scale made of reliable and shock-resistant engineering materials for increased durability and reliability. The non-contact grating design eliminates the need for bearings, seals, couplings and rails, thus eliminating the most common grating failures due to impact/vibration. Even if the main seal on the shaft fails, the sealing design of the RESOLUTE readhead prevents oil and coolant from entering; just wipe the readhead and scale clean and continue to use; this minimizes downtime and simplifies maintenance / maintenance work.
The contactless design also helps to improve system measurement performance. The rugged RESOLUTE circular encoder is locked to the shaft, thus avoiding problems such as mechanical backlash, shaft twisting errors and coupling errors that affect conventional sealed gratings. Circular encoders are available in a variety of models, such as models with an accuracy better than ±1 centiseconds or low moment of inertia models with grating sizes from 52 mm to 550 mm and custom sizes. In addition, the large through-hole design allows the grating to be mounted closer to the point to be measured without increasing the complexity of the installation and maintenance process. As a result, the system has stronger dynamic functions, shorter reset times, and improved repeatability.
Linear encoders made of stainless steel and ZeroMetTM (low-expansion nickel-iron alloy) also have the above advantages and can be mounted directly on machine structures or rails. Due to the unique precision scribe line single-channel absolute position code, the accuracy of the linear grating is better than ±1 micron, and the length of the steel tape scale can reach 10 meters.
RESOLUTE
The detection mode is inherently reliable with both advanced cross-checking and high redundancy. When the raster receives the location request, the location is calculated immediately, so each time the true absolute position is determined, this means that no counting errors or "lost counts" will occur. RESOLUTE's unique built-in position checking algorithm further enhances safety. Each time the raster receives a location request, RESOLUTE uses an algorithm to determine the location and then validates the result using a separate location checking algorithm. Therefore, any errors can be flagged on the controller before any servo control issues are formed. As a true absolute encoder, RESOLUTE can instantly determine position after opening, so it can fully control the motion axis without any movement, return to the reference position, and no backup battery. RESOLUTE is widely used in the medical, defense, and aerospace fields, and the most important consideration in these areas is the reliability of position data, and the safety features of RESOLUTE can be seen.
For machine tool builders, RESOLUTE offers a quick and easy installation experience. The scale is designed with ease of installation. The readhead has large mounting tolerances and a built-in LED mounting indicator on the readhead that displays the detected signal strength by color and issues a coded error alarm by flashing. . The LED indicator (also available at the remote DRIVE-CLiQ interface) also provides simple diagnostics throughout the entire raster application, eliminating the need for a dedicated test cartridge.
Please note that the RESOLUTE series can also be connected to a variety of industry-standard drives and controllers using several other serial protocols.
