17.6.3 Positioning Data Setting Areas
They are the areas for setting positioning data. The positioning data for 8 axes can be set individually.
The positioning data is stored in the table format of 625 points per axis.
When executing the automatic operation (position control) with the positioning unit RTEX, specify the
number of the positioning table that has been specified in advance, and start the position control. After
the start-up, the motor is automatically controlled according to the settings of the table. There are the
method that creates the positioning table using Configurator PM that is an exclusive setting tool, and the
other method that writes the positioning table in a prescribed address by ladder programs.
There are the standard area of 600 points that is specified by No. 1 to 600, and the extended area of 25
points that is specified by No. 10001 to 10025.
The standard area is used when the setting values of the positioning table are predetermined. It can be
set using Configurator PM, and can be rewritten from the ladder programs, too. However, if the
positioning table is changed by the ladder program, the calculation is necessary to restructure the
positioning data before executing the automatic operation. This function enables to read the positioning
data of 600 points in advance and to prepare for the start-up within the positioning unit, and enables to
shorten the start-up time for the positioning. When using Configurator PM to download the positioning
data, the data is restructured automatically, so the calculation is not necessary. However, the calculation
is necessary after rewriting the positioning data from the ladder program. The procedures for the
calculation are as follows.
1. Change the positioning table in the shared memory.
2. Turn on the output contact Y_7 (recalculation request contact).
3. Confirm the input contact X_7 (recalculation done contact) is on (Confirm the completion of the
recalculation.)
If the data is not recalculated after rewriting the positioning table by the ladder program, note that the
operation will be executed with the positioning table before the rewriting.
The extended area is used when the setting values of the positioning table cannot be determined until
just before executing the positioning operation. For example, in the application of alignment using an
image processing, the moving distance is determined by the image processing. Therefore, the
positioning table cannot be determined until just before starting the positioning operation. In that case,
the positioning table is set just before the start-up of the positioning. In the extended area, the positioning
table can be rewritten as needed, and the recalculation is not necessary. However, it is up to 25 tables,
and Configurator PM cannot be used. The ladder programs should be used to write the positioning table
in the prescribed address in the shared memory. The start-up time is longer than the standard area, and
when performing the P point control or C point control in the extended area, note that the start-up time
varies depending on the number of tables to be executed consecutively.
How to use each area and the precautions are as below.
