Incremental value command method ([Pr. PT01] = _ _ _ 1)
Setting "1" to the auxiliary function executes positioning at the speed set in the point table.
At this time, the position data selected at start is enabled, and the acceleration/deceleration time constant set in the next and
subsequent point tables is disabled.
By setting "1" to auxiliary functions until point table No. 254, the operation can be performed at maximum 255 speeds.
Be sure to set "0" to the auxiliary function of the last point table.
To perform varying-speed operation, be sure to set "0" to the dwell.
Setting "1" or more enables the automatic continuous positioning operation.
The following table shows an example of setting.
*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.
*1 Always set "0".
*2 Always set "0" to the auxiliary function of the last point table among the consecutive point tables.
