b) Positioning in the reverse direction midway
The following shows an operation example with the set values listed in the table below.
In this example, point table No. 1 and point table No. 3 are under the absolute value command
method, and point table No. 2 is under the incremental value command method.

No. [10 μm]
1 5.00
2 7.00
3 8.00
Note 1. Always set "0".
2. Always set "0" or "2" to the sub function of the last point table among the consecutive point tables.
0: When using the point table under the absolute value command method
2: When using the point table under the incremental value command method
