It is available with a 8 mm hub shaft and and a resolution up to 22 Bit Singleturn. The mechanical design consists of two ball bearings and a flexible torque support.

The AD35 complements the ACURO-DRIVE series and is appropriate for use within BLDC servo motors with small frame sizes. Further fields of Application: Medical Measuring instrument Military Robotics Fully digital control loop The new and completely digital OptoAsic technology enables the transition to a truly digital drive system. The conventional absolute encoders still have analog sine wave signals for the feedback of speed and position data. The AD35, however, provides fully digital position data up to 22 Bit over the BiSS interface with a variable clock rate up to 10 MHz. BiSS is the only open high speed bidirectional sensor interface available on the market.

Backward compatibility to most of the existing drives is realized through the variant with SSI interface together with 2048 sine -cosine periods per revolution. Integrated diagnostic system The AD35 has an integrated diagnostic system that controls and regulates the internal si- gnals. Maximum motor uptime is achieved through the pre warning in case of any system error or aging effects well before they affect the function of the encoder. A code plausibility check guarantees that the output data represents always the true position. Also the opera- ting temperature can be measured and read out with 8 Bit resolution.

If programmable limits are exceeded or under run this is indicated over warn and alarm bits.
