Absolute encoders - SSI Solid shaft with clamping flange, stainless steel housing Optical singleturn encoders 14 bit GE244 Terminal significance Terminal assignment UB Encoder voltage supply. GE244 GND Encoder ground connection relating to UB. Connector Core colour Assignment Data+ Positive, serial data output of differential linedriver. Pin 1 brown UB Data- Negative, serial data output of differential linedriver. Pin 2 black GND Pin 3 blue Clock+ Pin 4 beige Data+ Pin 5 green Zero setting Pin 6 yellow Data- Pin 7 violet Clock- Pin 8 brown/yellow UBminOK Pin 9 pink UP/DOWN Pin 10 black/yellow – Pin 11-12 – – Zero setting UBminOK UP/DOWN Incremental Outputs 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. Input for setting a zero point anywhere within the programmed encoder resolution. The zero setting operation is triggered by a High impulse and has to be in line with the selected direction of rotation (UP/DOWN). Connect to GND after setting operation for maximum interference immunity. Impulse duration >100 ms. GE244 with inremental tracks Diagnostic output. Level low indicates the operating voltage has dropped below the minimum limit. 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. Incremental tracks A 90° B and inverted.
