Absolute encoders - SSI / BiSS Shaft with clamping or synchro flange Single turn 9...19 bit, Absolute encoders - SSI / BiSS Mechanical Dimensions Cable/Connector Wiring, Part Number FNC AS 27 Series Terminal significance • Encoder single - or multiturn /SSI - BISS • Magnetic or optical sensing • Single turn resolution up to 21 bit • Synchro flange • System monitoring with error/warning messaging • Optional Prereset and direction input • Small form factor with sense position data Technical data - electrical ratings Technical data - mechanical design Voltage supply 8VDCto30VDC +Vs Encoder supply voltage. 0 V Encoder ground connection relating to +Vs Data+ Positive data output. Data- Negative data output. Clock+ Positive SSI clock input. Clock- Negative SSI clock input. Direction UP/DOWN counting direction input. This input is standart on High. UP/DOWN means ascending output data with clockwise shaft rotation when looking at flange. Preset Parameter for setting the encoder to a requested position value assigned to a defined shaft position of the system.The offset of encoder zero point and mechanical zero point is stored in the encoder. Output short circuit protection. Reverse polarity protection (except 5V version ) Shaft loading £20 N axial Consumption w/o load £80 mA (24 VDC) Interface SSI or BiSS Resolution (steps/turn) Magnetic: ^ bit _v K' Optic: 21 bit Absolute accuracy Magnetic.iOr ___Optic: ±0,01° Optoelectronic life time 100.000 (min) Starting torque Housing, Flange: Aluminium Shaft: Stainless steel Shaft diameter: Bearings lifetime: SSI differential clock Direction Electronic zero setting Operating temperature 6, 8, 10 mm (other diameters on request) 2x109 rev. at 100% of full rated shaft load (minimum) Output frequency Output circuit SSI data linedriver RS485 Pulse Diagram Clock frequency, f Code Status and parity bit Monoflop time tm 100... 4000 kHz for SSI up to 10MHz for BISS Binary or gray On request >5ps
