3.2.6 Saving and recalling a datum point using the scale reference point
(when the AT100 series is connected.)
Where the AT700 series is connected, refer to “3.2.6 Setting the machine origin with the
AT700 series”.
1) Saving the scale reference point
This operation saves the dimension between an appropriate reference point of the
Linear Scale and the datum point of the workpiece being machined, in the KA counter
as “origin data”. When the scale reference point is detected, the display is held for two
seconds, and this value is saved in the counter as “origin data”. The saved origin data
is not lost when the power is turned off, so it is possible to easily recall the machining
datum point on the workpiece being machined using the scale reference point recall
operation described in 2).
NOTE
Immediately after the power has been turned on, if the scale reference point recall
operation is performed at the beginning of work, as described in 2) below, it is not
necessary to perform this datum point recall operation.
• Saving the machining datum point in the X-axis direction using the scale reference
point.
Step 1 Use the keys so that the displayed value can be held when the scale reference
point is detected.
Step 2 Move the machine table in the direction of detecting the scale reference point.
When the scale reference point is detected, the displayed value is held, and a
buzzer sounds for two seconds. This display value (L) at this time is the
dimension to the scale reference point from the machining datum point, and is
automatically saved in the KA counter as “origin data”.
