(2) Auto tuning function block (PID7AT)
Function block
Description
Input
EN: enables PID7CAL function block (Level operation)
LOOP: sets execution loop (0~7)
Output
DONE : Turn on whenever the auto tuning operation is completed.
END : Turns on when the F/B operation is completed with no error, and
keep the status until next F/B execution.
STAT Displays the error code
MV: The manipulated value of current loop on which the auto tuning
operation is performed.
P: The proportional gain constant obtained by auto tuning operation.
I: The integral time constant obtained by auto tuning operation.
D: the derivative time constant obtained by auto tuning operation.
a) Usage
•
When the condition of the execution is On, PID auto tuning operation executes and calculates P,I,D constant.
•
LOOP No. (LOOP) designates the LOOP no. that is registered at the PID auto tuning parameter. (0~7)
•
Stat disignates the area where the PID auto tuning loop’s status is saved.
b)
Program example
•
When the input condition %IX0.0.0 turns On, the auto
tuning starts its operation following the parameter 0.
•
During the auto tuning, DONE state keeps On, and when
it finished END state turns On.
•
When an error occurs the STAT is ouputted at %MB100.
•
MV is saved in %MW10.
•
The P,I,D values are saved in %MW11,%MW12,%MW13
respectively.
