4. HOW TO USE THE POINT TABLE
4 - 28
2) Incremental value command method ([Pr. PT01] = _ _ _ 1)
Setting "1" to the auxiliary function executes positioning at the speed set in the following point
table.
At this time, the position data selected at start is valid, and the acceleration/deceleration time
constant set in the next and subsequent point tables is invalid.
By setting "1" to sub functions until point table No. 254, the operation can be performed at
maximum 255 speeds.
Always set "0" to the auxiliary function of the last point table.
To perform varying-speed operation, always set "0" to the dwell.
Setting "1" or more will enables the automatic continuous positioning operation.
The following table shows an example of setting.

4 0 1
Consecutive point table data 5 0 1
6
Disabled 0 (Note 2)
Note 1. Always set "0".
2. Always set "0" to the auxiliary function of the last point table among the
consecutive point tables.
The following shows an operation example with the set values listed in the table below.

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