3-1. Mounting Precautions
3-1-1. When Mounting
. The scale and the detector head are adjusted to each other. If using more than one scale unit, be sure that
the scale-head combinations have matching serial numbers.
. Consider the mounting position (Abbe error) and the environmental conditions (temperature, humidity,
vibration and dust) thoroughly.
. Do not lead the head 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. travel = measuring length +10 mm/0.39" (5 mm/0.20" per each side)
(If the scale's max. travel is exceeded, the scale unit signals 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 pages 3-3 to 3-11.)
3-1-2. Mounting Direction
Mounting can be performed in the vertical or horizontal direction.
The mounting direction shown in the figure is recommended when mounting in the horizontal direction.
