GXP1H Datasheet, PDF (3/4 Pages) Baumer IVO GmbH & Co. KG – Absolute encoders - parallel

Absolute encoders - parallel
Hollow shaft max. ø14 mm
Multiturn encoder 12 bit ST / 12 bit MT
GXP1H - parallel
Terminal significance
UB
Encoder voltage supply.
GND
Encoder ground connection relating to UB.
Outputs
D0-D23
24 parallel output signals.
For PNP it is recommended to utilize pull-
down resistors for every data line, for NPN
pull-up resistors of 4.7 kΩ.
Outputs
D19 - D23
Special outputs
With inferior resolutions these outputs
may be configurated as special outputs.
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.
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 counterclo-
ckwise 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.
RxD
Encoder receiver input for RS232 program-
ming interface.
TxD
Encoder transmitter output for RS232
programming interface.
