9.2 Setting the positioning data
9.2.1 Relation between each control and positioning data
The setting requirements and details for the setting items of the positioning data to be
set differ according to the " Da.2 Control method".
The following table shows the positioning data setting items corresponding to the
different types of control. Details and settings for the operation of each control are
shown in section 9.2.2 and subsequent sections.
(In this section, it is assumed that the positioning data setting is carried out using the
AD75 software package.)

: Always set : Set as required ("–" when not set) : Setting not possible : Setting limited
– : Setting not required (Setting value is invalid. Use the initial values or setting values within a range where no error occurs.)
* : The "ABS (absolute) method" or "INC (incremental) method" can be used for the control method.
REMARK
•
It is recommended that the "positioning data" be set whenever possible with the AD75 software package.
Execution by sequence program uses many sequence programs and devices. The execution becomes
complicated, and the scan times will increase.
•
A "Block transmission" is required when setting No. 101 and subsequent positioning data using a
sequence program.
