5 SERVO PROGRAMS FOR POSITIONING CONTROL

5.1.2 Servo program area

(3) Positioning data ...... This is the data required to execute servo instructions.
(1) Servo program area
This area is an internal memory of the Multiple CPU system which store the
servo program created using MT Developer2.
This area is an internal RAM.
(2) Servo program capacity
The servo program area has a capacity of 16384 steps.

POINT
If the servo program area has insufficient capacity, execute the multiple positioning
control operations with one program by indirect setting of the positioning data used
in the servo program. (Refer to Section 5.4.2 for details of indirect setting.)
The data required to execute is fixed for each servo
instruction.
Refer to Section 5.3 for details.
The follows applies for the servo program shown in Figure
5.1:
• Axis used and
positioning address
• Command speed
• Dwell time
• M-code
• P.B.
(parameter block)
Servo programs are stored in the order
in which their program No. were created.

Data which must be set in order to
execute the servo instruction.
Data which will be set to default
values for control if not set.
Control is executed using the data
of parameter block 3 (P.B.3).
