(a)
Example of setting the "#2 ZERO" parameter
For the "#2 Zero" parameter, set the coordinate value of the absolute position basic point (mechanical basic
position or electrical basic position) looking from the basic machine coordinate system zero point.
(Example 1)To set the zero point at 50.0mm before the absolute position basic point at machine end
(Example 2)To set the zero point at 400.0mm after the absolute position basic point at machine end
(Example 3)To set the basic machine coordinate system zero point on a grid point, calculate the "#2 Zero"
parameter setting value as shown below using the value displayed at "TO END". "TO END" shows the
distance from the mechanical basic position to the previous grid point.
Note that when setting the electrical basic position coordinate value for "#2 Zero", the "TO END" value
does not need to be considered.
To set the third grid point as zero point when the "TO END" display is -5.3 at the mechanical basic
position (with the grid space 10.0mm). )
