The operation for starting the positioning operation is mainly divided into five steps on a user
program.
• Read flags stored in the unit memories (input control area).
• Control the servo ON/OFF.
• Check the condition if the control of each axis can be started.
• Set positioning table numbers, check the conditions, and start the positioning operation.
• Write operation results in the unit memories (output control area).
(Note): The sample program on the next page is for activating the positioning operation with the table number 1 of the
axis number 1 for the FP7 MC Unit installed in the slot number 1. To simplify the explanation, the part related to
the positioning operation is extracted.
