TECHNICAL DATASHEET Absolute Motorfeedback Series AD 36 GENERAL INFORMATION For brushless servo motors Resolver size 15 compatible Through hollow shaft 8 mm Optical encoder with a true geared multiturn Interfaces: SSI, BiSS-B, BiSS-C The AD36 is an absolute encoder with a true geared Multiturn, optical sensing technology and 36 mm diameter. Unique is the through hollow shaft which enables an assembly that is compatible with resolver size 15. The mechanical design consists of two ball bearings and a flexible torque support. The AD36 complements the ACURO-DRIVE series and is appropriate for use within BLDC servo motors with small frame sizes. 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 AD36, however, provides fully digital position data up to 19 Bit (Singleturn) and 12 Bit (Multiturn) 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 va riant with SSI interface together with 2048 sine -cosine periods per revolution. Integrated diagnostic system The AD36 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. TECHNICAL DATA
