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 MT Diagnostic output. Multiturn sensor supply control. Upon dropping below a defined voltage level the DV MT output is switched to Low. UP/DOWN Trigger level SSI Edgeboard connector, 12-pin with litz 300 mm 2 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. www.baumerivo.com Subject to modification in technic and design. Errors and omissions excepted. 0 29/10/2008 GCM2K.
