Operation
1. When the instruction input is OFF: |
|
|
Initializes the FPID3 instruction. |
|
|
Operation mode is set as specified by B+17⋅B+16. | A+10 bit 0, 1 ← B+16 bit 0, 1 | |
Auto mode SV is set as specified by B+9⋅B+8. | ASV ← | ISV |
Manual mode MV is set as current MV. | MMV ← | MV |
Internal calculation data is initialized. |
|
|
MV remains unchanged. |
|
|
2.When the instruction input is ON:
Executes PID calculation every n scan which is specified by B+25⋅B+24. The following operation modes are available according to the setting of A+11⋅A+10.
•Auto mode
This is a normal PID control mode with ASV as set value.
Set value differential limit DSV, manipulation value upper/lower limit MH/ML and differential limit DMV are effective.
MMV is
