5 SERVO PROGRAMS FOR POSITIONING CONTROL
(2) Bit devices for indirect setting
The bit devices for indirect setting are the input (X), output (Y), internal relay (M),
link relay (B), annunciator (F) and Multiple CPU area device (U \G).
Bit devices except the above devices cannot be used.
The usable setting range of bit devices is shown below.

(Note-1): The range of "PXn+4 to PXn+F" cannot be used (fixed at 0) for the input device (PXn+0 to
PXn+F) allocated to the built-in interface in Motion CPU (DI). (n: First input No.)
(Note-2): "p" indicates the user setting area points of the Multiple CPU high speed transmission area
for each CPU.
Positioning
data
Fig. 5.5 Example of indirect setting by bit device for positioning data
(3) Inputting of positioning data
In indirect setting by word devices, the word device data is inputted when the
servo program is executed using the Motion CPU.
It must be executed the start request of the servo program after data is set in the
device used for indirect setting at the positioning control.
POINTS
(1) Indirect setting by word devices of the axis No. cannot be set in the servo
program.
(2) Take an interlock condition by using a start accept flag (M2001 to M2032) not to
change the device data for indirect setting until the specified axis has accepted
the start command.
If the data is changed before the start command is accepted, positioning may
not be controlled in a normal value.
(3) Refer to Chapter 2 of the "Q173D(S)CPU/Q172D(S)CPU Motion controller
Programming Manual (COMMON)" for the user setting area points of the
Multiple CPU high speed transmission area.
