Connector Assignment GND Encoder ground connection relating to UB. Pin 1 UB Data+ Positive, serial data output of differential linedriver. Pin 2 GND Data- Negative, serial data output of differential linedriver. Pin 3 Clock+ Pin 4 Data+ Pin 5 Zero setting Pin 6 Data- Pin 7 Clock- Pin 8 DATAVALID Pin 9 UP/DOWN Pin 10 DATAVALID MT Pin 11 – Pin 12 – Zero setting 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. 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. 8 7 2 3 5 11 Please use cores twisted in pairs (for example clock+ / clock-) for extension cables of more than 10 m length. 4 Trigger level 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 10 12 6 Diagnostic output. An error warning is given at level Low. Important: Interferences must be drained by the downstram electronics. 9 1 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. 3 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 Diagnostic outputs Output circuit Push-pull circuit-proof Output level High >UB -3.5 V (I = -20 mA) Output level Low <0.5 V (I = 20 mA) Load High <20 mA Load Low <20 mA www.baumerivo.com Subject to modification in technic and design. Errors and omissions excepted. Clock- 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. 14/11/2008 Clock+ Absolute encoders - SSI Shaft with clamping or synchro flange Optical multiturn encoders 14 bit ST / 12 bit MT GE400, GE401 - SSI Dimensions GM400 clamping flange 48±0.1 M3x7 (3x120°) 10 20 15 ø58 ø53 ø36f8 9 59 ø10h6 57 3 3 16 GE401 Synchro flange ø58 ø52 59 10 9 ø6f8 ø50h7 Subject to modification in technic and design.
