GXN1W Datasheet, PDF (3/4 Pages) Baumer IVO GmbH & Co. KG – Absolute encoders - parallel

Absolute encoders - parallel
Shaft with clamping or synchro flange
Multiturn encoder 12 bit ST / 12 bit MT / 250 cams
GXN1W
Terminal significance
UB
Encoder voltage supply.
GND
Encoder ground connection relating to UB.
Outputs
D0-D15
16 programmable cams outputs.
For PNP it is recommended to utilize pull-
down resistors, for NPN pull-up resistors
of 4.7 kΩ.
Outputs
D17-D19
Outputs less any function.
There must not be any external circuit.
Outputs
D19 - D23
Special outputs.
These outputs may be assigned to special
functions.
Zero setting
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
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).
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).
