Encoders feature DRIVE-CLiQ output

Encoders feature DRIVE-CLiQ output New from Renishaw are RESOLUTE true-absolute linear and rotary (angle) encoders with new compatibility for Siemens DRIVE-CLiQ - the innovative, powerful communications interface to connect encoder and direct measurement systems with SINUMERIK and SINAMICS drive components. Allowing machine builders to achieve higher performance and greater reliability, this product conforms to Category 2 in accordance with EN 13849 and so is suitable for use in safety-related axes such as linear motors and direct drive rotary (DDR) torque motors.

RESOLUTE's unique operating principle is analogous to an ultra-high speed digital camera, capturing images of the scale, enabling resolutions up to 1nm to be achieved (32-bit on rotary) even at speeds up to 100m/s (36,000 rev/min on rotary). Advanced optics mean the detection scheme also has intrinsic low Sub-Divisional Error (SDE) and very low noise (jitter), so users can benefit from lower velocity ripple and rock-solid positional stability.

Such high-fidelity motion control performance is normally only associated with much more fragile encoders, but RESOLUTE adds ruggedness and reliability, with sealed read heads and scales constructed from dependable shatter-proof engineering materials. The non-contact format eliminates bearings, seals, couplings and guideways from the encoder design, thereby also eliminating the most common causes of shock / vibration-induced encoder failure. Even if the main seals on the axis fail, RESOLUTE read heads are sealed against ingress of oil and coolant; simply wipe the read head and scale, then start working again. Downtime is minimised and servicing and repair are simplified. The non-contact format also helps to improve system metrology.
