machine's travel and check that the detecting surface of
the head and the scale are not in contact.
• After installing the head, use the accessory cable clamps
to securely fasten the cable where it extends from the
head.
• The relative positions of the scale unit and head unit
should be as shown in "3-4. Head unit and scale unit" .
