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. Also, do not bundle the head cable
and power cable together using a tie.

•

Install in a location that is at least 0.5 meters separated from sources of high voltage and large currents
and large power relays.

•

Do not use the cable connecting the detector head to the interface unit in a location where it is likely to be
repeatedly subjected to a bending force (cable bear, etc.). In such a case, bend the cable connected to the
output connector on the interface unit.

•

Use this product in an environment with an ambient temperature of 0 to 40

Do not attach it to a location that is exposed to direct sunlight or warm air or near sources of heat such as
motors. This could adversely affect the accuracy.

•

If using a water-soluble cutting fluid or other substances, ensure that there is adequate protection so that
it does not adhere to the scale.

•

Set the maximum travel of the machine’s moving part shorter than that of the scale.

Scale’s max. travel = measuring 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 3-13.)

•

When mounting and adjusting the detector head, do not touch the surface of the head cover indicated by
the arrows in the drawing below.
