4. HOW TO USE THE POINT TABLE
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.

2 7.00
3 8.00
Note. Always set "0" or "2" to the auxiliary 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

Note. For MR-J4-03A6-RJ servo amplifiers, up to six points of DO are available; therefore, PT0 to PT7 cannot be outputted
simultaneously.
