Absolute encoders - parallel Hollow shaft max. ø14 mm Multiturn encoder 12 bit ST / 12 bit MT Terminal assignment UB Encoder voltage supply. Connector Core colour Assignment GND Encoder ground connection relating to UB. Pin 1 white Output D0 Outputs D0-D23 24 parallel output signals. For PNP it is recommended to utilize pulldown resistors for every data line, for NPN pull-up resistors of 4.7 kΩ. Pin 2 brown Output D1 Outputs D19 - D23 Zero setting UP/DOWN ENABLE STORE Special outputs With inferior resolutions these outputs may be configurated as special outputs. 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. UP/DOWN counting direction input. Without potential this input is on High. UP/DOWN High means ascending output data with clockwise hollow 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.
