Zero setting
DATAVALID
Negative SSI clock input.
Clock- together with clock+ forms a current
loop. A current of approx. 7 mA towards
clock- input means logic 0 in positive logic.
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.
GXM2S with incremental tracks
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
Incremental
Outputs
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.
