Errors and omissions excepted. Absolute encoders - parallel Shaft with clamping or synchro flange Singleturn encoder, capped gray code GXA1W - parallel Terminal significance UB GND Outputs D0-D11 UP/DOWN Encoder voltage supply. Encoder ground connection relating to UB. Up to 12 parallel output signals. 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. Input for activating the output drivers that are triggered by input level Low. Upon being on High (or less potential) the output drivers switch to high-impedance (Tristate). Input for output data storage. Upon a Low input level the encoder data are stored in the intermediate memory. Upon being on High (or less potential) the current encoder position data are switched to the output drivers. This line must be applied for reliable data readout in binary code.
