2. Mounting Precautions

2-1. 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 serial No. on the supplied accuracy chart.
. 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.
Measuring length = 10 or 30 mm:
Scale's max. travel = measuring length +2 mm/0.08" (1 mm/0.04" per each side)
Measuring length = 70 mm or more:
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 4 to 12.)
. Be sure to set the detector to the compensation value of the scale before operation.
