Accessories Absolute encoders - parallel Shaft with clamping or synchro flange Singleturn encoder, capped gray code GXA1W - parallel Terminal significance Terminal assignment UB Encoder voltage supply. Connector Core colour GND Encoder ground connection relating to UB. Pin 1 violet Output D0 Output D0 Outputs D0-D11 Up to 12 parallel output signals. Pin 2 white/brown Output D1 Output D1 UP/DOWN 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. Pin 3 white/green Output D2 Output D2 Pin 4 white/yellow Output D3 Output D3 Pin 5 white/grey Output D4 Output D4 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. Pin 6 white/pink Output D5 Output D5 Pin 7 white/blue Output D6 Output D6 Pin 8 white/red Output D7 Output D7 Pin 9 white/black Output D8 Output D8 Pin 10 green/brown Output D9 Output D8 Pin 11 green/grey Output D10 N.C.
