5-11. Detecting Function of Absolute Zero Point of Scale
•
This function is valid in combination with a scale with built-in absolute zero point.
Once the distance L between the machining datum point and the absolute zero point of the
scale is found, the machining datum point can be relocated easily for repeated machining.
•
When the unit is set to the detecting mode of the absolute zero point of the scale, the “
” mark
and the ABS mark are displayed.
•
If a load or hold operation has been erroneously performed, press the relevant Axis selector key
and the
key to cancel the operation, and perform the load or hold operation again.
