Core colour Assignment GND Encoder ground connection relating to UB. brown UB Data+ Positive, serial data output of differential linedriver. white GND Data- Negative, serial data output of differential linedriver. green Clock+ grey Data+ blue Zero setting pink Data- yellow Clock- Clock- Zero setting Positive SS 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. black DATAVALID 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. red UP/DOWN violet DATAVALID MT 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. Trigger level SSI Circuit SSI-Clock Optocoupler SSI-Data Linedriver RS485 Control inputs Input circuit Input level High >0.7 UB Input level Low <0.3 UB Input resistance 10 kΩ 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. Output Linedriver RS422 Output level High >2.5 V (I = -20 mA) Output level Low <0.5 V (I = 20 mA) UP/DOWN Load High <20 mA Load Low <20 mA Diagnostic output. An error warning is given at level Low. Important: Interferences must be drained by the downstram electronics. 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.
