DATAVALID MT
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.
Trigger level
Diagnostic output.
An error warning is given at level Low.
Important: Interferences must be drained
by the downstram electronics.
DATAVALID MT Diagnostic output for monitoring the
multiturn sensor voltage supply. Upon
dropping below a defined voltage level the
DV MT output is switched to Low.
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.
