GXA1W Datasheet, PDF (3/4 Pages) Baumer IVO GmbH & Co. KG – Absolute encoders - parallel

Absolute encoders - parallel
Shaft with clamping or synchro flange
Singleturn encoder, capped gray code
GXA1W - parallel
Terminal significance
UB
Encoder voltage supply.
GND
Encoder ground connection relating to UB.
Outputs
D0-D11
Up to 12 parallel output signals.
UP/DOWN
UP/DOWN counting direction input.
This input is standard on High. UP/DOWN
means ascending output data with clock-
wise shaft rotation when looking at flange.
UP/DOWN-Low means ascending values
with counterclockwise shaft rotation when
looking at flange.
ENABLE
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).
STORE
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.
