nnnnINTERFACE
nnnnC€
nnnnThe AD36 is an absolute encoder with a true geared Multiturn, optical sensing technology
nnnnand 36 mm diameter. Unique is the through hollow shaft which enables an assembly that is
nnnncompatible with resolver size 15. The mechanical design consists of two ball bearings and a
nnnnflexible torque support. The AD36 complements the ACURO-DRIVE series and is appropriate
nnnnfor use within BLDC servo motors with small frame sizes.
nnnnFully digital control loop
nnnnThe new and completely digital OptoAsic technology enables the transition to a truly digital
nnnndrive system. The conventional absolute encoders still have analog sine wave signals for
nnnnthe feedback of speed and position data. The AD36, however, provides fully digital position
nnnndata up to 19 Bit (Singleturn) and 12 Bit (Multiturn) over the BiSS interface with a variable
nnnnclock rate up to 10 MHz. BiSS is the only open high speed bidirectional sensor interface
nnnnavailable on the market. Backward compatibility to most of the existing drives is realized
nnnnthrough the va riant with SSI interface together with 2048 sine -cosine periods per revolution.
nnnnIntegrated diagnostic system
nnnnThe AD36 has an integrated diagnostic system that controls and regulates the internal si-
nnnngnals. Maximum motor uptime is achieved through the pre warning in case of any system
nnnnerror or aging effects well before they affect the function of the encoder. A code plausibility
nnnncheck guarantees that the output data represents always the true position. Also the opera-
nnnnting temperature can be measured and read out with 8 Bit resolution. If programmable limits
nnnnare exceeded or under run this is indicated over warn and alarm bits.
