APPLICATIONS

nnnn

The AC 36 is an absolute optical encoder with a true geared multiturn, optical sensing tech-

nnnn

nology and 36 mm diameter. Equiped with a solid-shaft the AC 36 is mechanical compatible

nnnn

with all common inkremental encoders. The compact design allows to replace the adequate

nnnn

incremental encoders directly. As a result the technical facilities of absolute encoders can

nnnn

be used for the first time in equipment engineering and also in medical engineering. The

nnnn

mechanical design consists of two ball bearings supported mechanical shaft assembly. The

nnnn

AC 36 complements the ACURO ®-industry series with small frame sizes and the same per-

nnnn

formance as 58 mm versions.

nnnn

BiSS-lnterface

nnnn

Unique within his class the AC 36 provides fully digital position data up to 17 Bit (singleturn)

nnnn

and 12 Bit (multi-turn) over the bidirectional synchronous interface with a variable clock

nnnn

rate up to 10 MHz. This corresponds a singleturn resolution of more than 130 000 mesured

nnnn

steps. Backward compatibility is realized through the SSI interface together with 2048 sine-

nnnn

cosine periods per revolution.

nnnn

Integrated diagnostic system

nnnn

The AC 36 is based on latest OptoAsic technology with an advanced diagnostic concept. A

nnnn

continous plausibility check controls the internal signal processing for each increment. A

nnnn

code check guarantees that the encoder signal represents bit by bit the mesured rotation.

nnnn

Also the operating temperature of the encoder can be measured, read out and monitored

nnnn

over warn and alarm bits with 8 bit resolution (1°C). Monitoring and controlling of the ope-

nnnn

rating temperature ensures a maximum lifetime of the LED. Eventual failures are indicated

nnnn

early over warn bits.
