Mitsubishi Electronics Q172HCPU, Q173HCPU POINT, (1)Servo program area, 5.1.2Servo program area, (2) Servo program capacity, Fig. 5.2 Servo program area, 5 SERVO PROGRAMS FOR POSITIONING CONTROL

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).

5 SERVO PROGRAMS FOR POSITIONING CONTROL

(3) Positioning data ...... This is the data required to execute servo instructions.

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.
