Major positioning control
Positioning data
[Da.20] Axis to be interpolated 1
[Da.21] Axis to be interpolated 2
[Da.22] Axis to be interpolated 3
: Always set
: Set as required ("–" when not required)
: Setting not possible (If set, the error "Continuous path control not possible" (error code: 516) will occur at start.)
– : Setting not required (If the value is the default value or within the setting range, there is no problem.)
: Two control systems are available: the absolute (ABS) system and incremental (INC) system.

Checking the positioning data
[Da.1] to [Da.10], [Da.20] to [Da.22] are checked at the following timings:
 Startup of a positioning operation
The "block start data" must be set when carrying out "high-level positioning control".
The setting items for the "block start data" are shown below.
Up to 50 points of "block start data" can be set for each axis.
Refer to Chapter 10 "High-Level Positioning Control" for details on the "high-level
positioning control", and to Section 5.4 "List of block start data" for details on each
setting item.
