8-1 Section Outline

The PCU carries out positioning using the speeds, acceleration times, decelera-
tion times and dwell times set in the designated sequence numbers. The posi-
tions have the same numbers as the positioning sequences.

Note Since the sequence number is saved in the PCU, the PCU is capable of execut-
ing the subsequent sequence after being stopped with the deceleration stop.
However, if the origin search, origin return, or present position preset is
executed, this sequence number will be lost. Therefore, the sequence number
needs to be set to “enable” and the PCU must be restarted.
8-1-1 Axis Designation
Which axis is to be positioned with the positioning sequence is specified by the
axis designation within the positioning sequence. The positions used are those
for the axes designated by the axis designation. For data other than position
data, the data of the axis that started operation is used as the data to be desig-
nated in the sequence data.

If several axes are designated by the axis designation, interpolated operation
will be executed for the designated axes.

8-1-2 Axis Designation and Flags
The status and present position allocated to the operating memory area and
operating data area are input for the “starting axis” (i.e. the axis whose position-
ing sequence is used to start operation) and for the “designated axis/axes” (i.e.,
the axis/axes specified in the axis designation of the positioning sequence).
