nnnnAPPLICATIONS
nnnnThe AC 36 is an absolute optical encoder with a true geared multiturn, optical sensing tech-
nnnnnology and 36 mm diameter. Equiped with a solid-shaft the AC 36 is mechanical compatible
nnnnwith all common inkremental encoders. The compact design allows to replace the adequate
nnnnincremental encoders directly. As a result the technical facilities of absolute encoders can
nnnnbe used for the first time in equipment engineering and also in medical engineering. The
nnnnmechanical design consists of two ball bearings supported mechanical shaft assembly. The
nnnnAC 36 complements the ACURO ®-industry series with small frame sizes and the same per-
nnnnformance as 58 mm versions.
nnnnBiSS-lnterface
nnnnUnique within his class the AC 36 provides fully digital position data up to 17 Bit (singleturn)
nnnnand 12 Bit (multi-turn) over the bidirectional synchronous interface with a variable clock
nnnnrate up to 10 MHz. This corresponds a singleturn resolution of more than 130 000 mesured
nnnnsteps. Backward compatibility is realized through the SSI interface together with 2048 sine-
nnnncosine periods per revolution.
nnnnIntegrated diagnostic system
nnnnThe AC 36 is based on latest OptoAsic technology with an advanced diagnostic concept. A
nnnncontinous plausibility check controls the internal signal processing for each increment. A
nnnncode check guarantees that the encoder signal represents bit by bit the mesured rotation.
nnnnAlso the operating temperature of the encoder can be measured, read out and monitored
nnnnover warn and alarm bits with 8 bit resolution (1°C). Monitoring and controlling of the ope-
nnnnrating temperature ensures a maximum lifetime of the LED. Eventual failures are indicated
nnnnearly over warn bits.
