TECHNICAL DATASHEET Absolute Encoder AC 36 - BiSS / SSI For equipment engineering and industry Up to 17 Bit Resolution Singleturn + 12 Bit Multiturn Solid shaft 6 mm (Hollow shaft version: AD 36) Optical encoder with a true geared multiturn Interfaces: SSI, BiSS-B or BiSS-C The AC 36 is an absolute optical encoder with a true geared multiturn, optical sensing tech- nology and 36 mm diameter. Equiped with a solid-shaft the AC 36 is mechanical compatible with all common inkremental encoders. The compact design allows to replace the adequate incremental encoders directly. As a result the technical facilities of absolute encoders can be used for the first time in equipment engineering and also in medical engineering. The mechanical design consists of two ball bearings supported mechanical shaft assembly. The AC 36 complements the ACURO ®-industry series with small frame sizes and the same per- Unique within his class the AC 36 provides fully digital position data up to 17 Bit (singleturn) and 12 Bit (multi-turn) over the bidirectional synchronous interface with a variable clock rate up to 10 MHz. This corresponds a singleturn resolution of more than 130 000 mesured steps. Backward compatibility is realized through the SSI interface together with 2048 sine- cosine periods per revolution. Integrated diagnostic system The AC 36 is based on latest OptoAsic technology with an advanced diagnostic concept. A continous plausibility check controls the internal signal processing for each increment. A code check guarantees that the encoder signal represents bit by bit the mesured rotation. Also the operating temperature of the encoder can be measured, read out and monitored over warn and alarm bits with 8 bit resolution (1°C). Monitoring and controlling of the ope- rating temperature ensures a maximum lifetime of the LED. Eventual failures are indicated early over warn bits. TECHNICAL DATA
