Positioning Data Setting

Relation between each control and positioning data

The setting requirements and details on the setting items of the positioning data differ according to the setting in [Da.2] Control
method.
The following table shows the setting items of positioning data prepared for various control systems. (The settings of
positioning data in this section are assumed to be performed using an engineering tool.)
: Always set, : Set as required
: Setting not possible (If these items are set, Continuous path control not possible (Error code: 1A1EH, 1A1FH) occurs at
the start.)
: Setting not required (The set value is ignored. Set the value within the setting range, such as the initial value.)
