Absolute encoders - SSI Shaft with clamping or synchro flange Optical multiturn encoder 13 bit ST / 12 bit MT GXP2W - SSI Terminal significance Terminal assignment UB Encoder voltage supply. Connector Core colour Assignment GND Encoder ground connection relating to UB. Pin 1 violet Data+ Data+ Positive, serial data output of differential linedriver. Pin 2 brown/white Data- Data- Negative, serial data output of differential linedriver. Pin 3 green/white – Pin 4 yellow/white TxD Clock+ Positive SSI clock input. Clock+ together with clock- forms a current loop. A current of approx. 7 mA towards clock+ input means logic 1 in positive logic. Pin 5 grey/white RxD Pin 6 pink/white Clock+ Pin 7 blue/white Clock- UP/DOWN Preset input for setting a preset anywhere within the programmed encoder resolution. The preset operation is triggered by a High impulse and has to be in line with the selected rotating direction UP/DOWN. Connect to GND for maximum interference immunity. Impulse duration >100 ms. UP/DOWN counting direction input. This input is standard on High. UP/DOWN means ascending output data with clockwise shaft rotation when looking at flange. UP/DOWN-Low means ascending values with counterclockwise shaft rotation when looking at flange. The rotating direction may also be altered by programming. TxD Encoder transmitter output for RS232 programming interface. RxD Encoder receiver input for RS232 programming interface. Pin 8 red/white Output 1 Pin 9 black/white Output 2 Pin 10 green/brown Output 3 Pin 11 green/grey Output 4 Pin 12 blue GND Pin 13 yellow Preset Pin 14 brown UP/DOWN Pin 15 red UB Pin 16 pink GND-PRG 11 10 16 9 15 8 12 7 1 2 13 3 14 6 Please use cores twisted in pairs (for example clock+ / clock-) for extension cables of more than 10 m length. 4 5 Trigger level SSI Circuit SSI-Clock Optocoupler Outputs 1, 3, 4 Special outputs.

Preset Negative SSI clock input. Clock- together with clock+ forms a current loop. A current of approx. 7 mA towards clock- input means logic 0 in positive logic. 30/10/2008 Clock- Absolute encoders - SSI Shaft with clamping or synchro flange Optical multiturn encoder 13 bit ST / 12 bit MT GXP2W - SSI Dimensions GXP2W clamping flange 10 20 57 10 20 15 ø58 10 20 57 10 20 15 ø10 h6 9 ø58 ø53 ø36 f8 9 59 ø10 h6 15 3 20 ø53 3 3 57 ø58 3 3 48 ±0.1 M3x7 (3x120°) ø53 ø10 h6 9 11.5 ø58 ø53 ø10 h6 ø36 f8 9 15 20 ø36 f8 15 ø36 f8 57 48 ±0.1 M3x7 (3x120°) 3 3 3 16 16 ø58 ø52 59 58 3 4 www.baumerivo.com Subject to modification in technic and design.
