Example 2
1. Add one line to the program in Example 1. When the PLC runs and SM1662 is ON, the function is enabled for servo
2 to go back and forth.
2. As the figure shows below, the servo moves from its current position (20,000) to the absolute target position
(100,000) after M2 is ON. After that, it goes back and forth between the absolute position 100,000 and 0.
The direction indication flag SM1672 is ON when the servo goes toward the target position for the first time after
Servo-ON. After that, the flag repeats the state, changing from ON to OFF.
3. You can modify the target position at any time in the motion, but the new target position is only valid for the next
back and forth cycle.
