4. HOW TO USE THE POINT TABLE
4 - 19
2) Incremental value command method ([Pr. PT01] = _ _ _ 1)
While the servo motor is stopped under servo-on state, switching on ST1 (Forward rotation start)
or ST2 (Reverse rotation start) starts the automatic positioning operation.
The following shows a timing chart.

Note 1. The detection of external input signals is delayed by the set time in the input filter setting of [Pr. PD29].
Considering the output signal sequence from the controller and signal variations due to hardware, configure a
sequence that changes the point table selection earlier.
2. For MR-J4-03A6-RJ servo amplifiers, up to six points of DO are available; therefore, PT0 to PT7 cannot be
outputted simultaneously.
