Absolute encoders - parallel Shaft with clamping or synchro flange Multiturn encoder 12 bit ST / 12 bit MT / 250 cams Terminal assignment UB Encoder voltage supply. Connector Core colour Assignment GND Encoder ground connection relating to UB. Pin 1 white Output D0 Outputs D0-D15 16 programmable cams outputs. For PNP it is recommended to utilize pulldown resistors, for NPN pull-up resistors of 4.7 kΩ. Pin 2 brown Output D1 Outputs D17-D19 Outputs D19 - D23 Zero setting UP/DOWN ENABLE GND-Sense UB-Sense Outputs less any function. There must not be any external circuit. Special outputs. These outputs may be assigned to special functions. 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. 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). Internally connected to GND and serves together with UB-Sense for measuring the encoder voltage supply. 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 – Pin 18 pink/brown – Pin 19 white/black – 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 – – 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.
