4. HOW TO USE THE POINT TABLE
(c) Varying-speed operation
By setting the auxiliary function of the point table, the servo motor speed during positioning can be
changed. Point tables are used by the number of the set speed.
1) Absolute value command method ([Pr. PT01] = _ _ _ 0)
Set "1" or "3" to the auxiliary function to execute the 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" or "3" to sub functions until point table No. 254, the operation can be performed at
maximum 255 speeds.
Always set "0" or "2" 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.
