Output D1
DATAVALID
Diagnostic output.
An error warning is given at level Low.
Important: Interferences must be filtered by
the downstram electronics.
ENABLE
STORE
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).
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.

UP/DOWN
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.
