7.6 Homing the product
To detect the product's position, it is equipped with a measuring
system which can detect the finger's spatial location at a high
resolution. Due to the incremental method of position detection,
the product has to be homed before motion commands can be
executed.
The product has a special command for homing which can be
issued via the command interface, by a script or via the web
interface. It then moves its fingers to the inner or outer physical
limit and saves the measured position as a reference value. To
offer maximum flexibility, the product can be referenced to the
inner as well as to the outer limit. For outer homing, a factory-
calibrated value is used to shift the reference position, so that
both variants end up with the same direction and the same origin
for the axis coordinates.
NOTE
• Make sure that the fingers can actually move freely in the
reference drive direction up to the product’s mechanical limit.
• The homing movement should be carried out in the direction of
the required positioning accuracy.
• To automatically execute a homing sequence on start up,
activate the "Homing on Start up" option via the web interface
Settings -> Motion Configuration).
