RXA1H Datasheet, PDF (3/4 Pages) Baumer IVO GmbH & Co. KG – Absolute encoders - parallel

Absolute encoders - parallel
Hollow shaft ø14 mm
Singleturn encoder 13 bit, 1024 cams
RXA1H
Terminal significance
UB
Encoder voltage supply.
GND
Ground connection of encoder and output
drivers relating to UB.
Outputs
1-16
16 programmable cams outputs.
Each output enables optionally alternative
configuration as special output.
Zero setting
Input for setting a zero point anywhere
within the programmed encoder resolution.
The zero setting operation is released by a
High impulse and has to be in line with the
selected counting direction (UP/DOWN).
Connect to GND after reset operation for
maximum interference immunity. Impulse
duration >100 ms.
For safety reasons any reset operation will
immediately stop a running cams program.
Start
Program start input.
Applying a High potential (UB) for at least
100 ms will start the selected cams
program. If the start input is firmly con-
nected to UB, the cams program selected
at the programming inputs will immediately
start after encoder power on.
Programs
Inputs for program selection 1-16.
Preset of the cams program in binary code.
Program 1 is selected by code 0-0-0-0
program 16 by 1-1-1-1.
Input „Program 1“: Valence „1“
Input „Program 2“: Valence „2“
Input „Program 4“: Valence „4“
Input „Program 8“: Valence „8“
After encoder power on and upon every
alteration at the programming inputs the
cams program selection by the four
programming inputs will be valid. A later
selection by serial programming interface
will overwrite the selection made at the four
programming inputs. Every alteration of the
program inputs will immediately stop a
running cams program.
VPOS1
VPOS2
Separate voltage supply of output driver
(outputs 1-8: pin 32, outputs 9-16: pin 33).
GND-PRG
Separate ground of programming interface
RS232.
RxD
Encoder receiver input for RS232 program-
ming interface.
TxD
Encoder transmitter output for RS232
programming interface.
