4. MOUNTING PRECAUTIONS
4-1. When Mounting
• The scale and the detector head are adjusted to each
other.
If more than one scale unit is to be used, only combine
them with the detector heads provided in the same
packing. If you do not know which scale and detector head
to use together, refer to the No. on the packing carton.
• Consider the mounting position (Abbe error) and the
environmental conditions (temperature, humidity,
oscillation and dust) thoroughly.
• Do not lead the head connector cable through the same
duct with the power cable.
• Set the maximum travel of the machine’s moving part
shorter than that of the scale.
Scale’s max. trave : effective measuring length ＋ 10 mm
/0.39" (5 mm/0.20" per each side)
(If the scale’s max. travel is exceeded, the signals of the
scale unit will not be output and an error will occur.)
• For the scale unit, scale signal adjustment is necessary
after mounting.
When mounting the scale to the machine, make sure that
there is enough space for the adjustment.
(see page 23 to 32)
• To protect the scale against external light, dust, oil, etc.,
only use it with the cover.
• Be sure to set the display unit or detector to the
compensation value of the scale before operation.
