(c) Operation at the completion of program control
After the PID control of the final segment set by the final segment completes
and reaches the pattern end, the pattern end output is performed.
• The pattern end output continues the PID control at the set value of the
final segment for the time set by the output time setting of pattern end
(buffer memory address: 323, 387, 451, 579, 643, 707).
• During the pattern end output, 1 is stored in the pattern end output flag
(buffer memory address: 259, 515).
• After the completion of the pattern end output, the program control
completes, 1 is stored in the end status flag (buffer memory address: 260,
516), and the program control becomes a reset status.
• At the RESET status, the PID control is stopped, and the stored value is 0
and the output is turned off*4.
*4: The current value output at the RESET is the value set by the lower
output limiter (buffer memory address: 43, 75).
POINT
When executing the program control continuously, wait for more than 0.05 seconds
after resetting the first program control, and then set the program control
RUN/RESET to RUN. (Set 1 for the buffer memory address: 57, 89.)
