4. HOW TO USE THE POINT TABLE
c) Varying-speed operation by absolute value command method
Example. Operations when "8" is set to the auxiliary function of point table No. 3

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) Executing point table No. 1 used at start-up in CW direction when "8" is set to the auxiliary
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)
