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.

Start
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.
