Absolute encoders - parallel Shaft with clamping or synchro flange Optical 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. If there is an offset being entered by programming interface the offset will be activated by the zero input. 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. GND-Sense Internally connected to GND and serves together with UB-Sense for measuring the encoder voltage supply. UB-Sense Internally connected to UB. In case the sensor line is not utilized the connection must be isolated (danger of short circuit). 3 Pin 3 green Output D2 Pin 4 yellow Output D3 Pin 5 grey Output D4 Pin 6 pink Output D5 Pin 7 black Output D6 Pin 8 violet Output D7 Pin 9 grey/pink Output D8 Pin 10 red/blue Output D9 Pin 11 white/green Output D10 Pin 12 brown/green Output D11 Pin 13 white/yellow Output D12 Pin 14 yellow/brown Output D13 Pin 15 white/grey Output D14 Pin 16 grey/brown Output D15 Pin 17 white/pink Output D16 Pin 18 pink/brown Output D17 Pin 19 white/black Output D18 Pin 20 brown/black Output D19 Pin 21 grey/green Output D20 Pin 22 yellow/grey Output D21 Pin 23 pink/green Output D22 Pin 24 yellow/pink Output D23 Pin 25 – – Pin 26 – – Pin 27 yellow/blue Zero setting Pin 28 brown/blue ENABLE Pin 29 brown/red STORE Pin 30 green/blue UP/DOWN Pin 31 – – Pin 32 – – Pin 33 – – Pin 34 white/blue GND-Sense Pin 35 white/red UB-Sense Pin 36 red UB Pin 37 blue GND www.baumerivo.com 29/10/2008 Terminal significance Subject to modification in technic and design.
