INTERFACE

nnnn

C€

nnnn

The AD36 is an absolute encoder with a true geared Multiturn, optical sensing technology

nnnn

and 36 mm diameter. Unique is the through hollow shaft which enables an assembly that is

nnnn

compatible with resolver size 15. The mechanical design consists of two ball bearings and a

nnnn

flexible torque support. The AD36 complements the ACURO-DRIVE series and is appropriate

nnnn

for use within BLDC servo motors with small frame sizes.

nnnn

Fully digital control loop

nnnn

The new and completely digital OptoAsic technology enables the transition to a truly digital

nnnn

drive system. The conventional absolute encoders still have analog sine wave signals for

nnnn

the feedback of speed and position data. The AD36, however, provides fully digital position

nnnn

data up to 19 Bit (Singleturn) and 12 Bit (Multiturn) over the BiSS interface with a variable

nnnn

clock rate up to 10 MHz. BiSS is the only open high speed bidirectional sensor interface

nnnn

available on the market. Backward compatibility to most of the existing drives is realized

nnnn

through the va riant with SSI interface together with 2048 sine -cosine periods per revolution.

nnnn

Integrated diagnostic system

nnnn

The AD36 has an integrated diagnostic system that controls and regulates the internal si-

nnnn

gnals. Maximum motor uptime is achieved through the pre warning in case of any system

nnnn

error or aging effects well before they affect the function of the encoder. A code plausibility

nnnn

check guarantees that the output data represents always the true position. Also the opera-

nnnn

ting temperature can be measured and read out with 8 Bit resolution. If programmable limits

nnnn

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