UB Encoder voltage supply. GND Encoder ground connection relating to UB. Data+ Positive, serial data output of differential linedriver. Data- Negative, serial data output of differential linedriver. 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. Clock- 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. Zero setting 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. DATAVALID Diagnostic output. An error warning is given at level Low. Important: Interferences must be filtered by the downstram electronics. DATAVALID MT Diagnostic output for monitoring the multiturn sensor voltage supply. Upon dropping below a defined voltage level the DV MT output is switched to Low. UP/DOWN UP/DOWN counting direction input. This input is standard on High. UP/DOWN means ascending output data with clock- wise shaft rotation when looking at flange. UP/DOWN-Low means ascending values with counterclockwise shaft rotation when looking at flange.
