Prior checks
Casting marks on the incremental encoder
► You must set the exact height to the scale.
► Align the incremental encoder, using the two casting
marks (arrows), which mark the read area.
► Tighten the fastening screws.
► Reconnect to the electricity supply (X15 or X24).
CAUTION!
Check how the cables are run!
Make sure that the axes can be moved without damaging
the cables.
Fasten the cables with cable ties.
► Move the gantry into the end stopper and check that
the bumper does not come into contact with the ca
