4. HOW TO USE THE POINT TABLE
d) Varying-speed operation by incremental value command method
Example. Operations when "10" is set to the sub function of point table No. 3

No. [10 μm]
1 5.00
2 10.00
3 5.00
Operation sequence
1) Starting with point table No. 1
2) Varying the speed and executing point table No. 2
3) Varying the speed and executing point table No. 3
4) Varying the speed, and executing point table No.1 when "10" is set to the sub function of
point table No. 3
5) Repeating the above execution in the sequence of 1) to 2) to 3) to 4) to 2) to 3) to 4)
