Functions
PID Operation
P Operation
•Operation where the control volume is proportional to the target value
I Operation
•Operation where the control volume increases linearly according to time
D Operation
•Operation where the control volume is proportional to the variation ratio of the target value
•PI operation is the combination of the above P and I operations; PD is P and D operations; PID is
P, I and D operations.
Feedback Selection
•Select a terminal used for feedback signals in PID feedback selection A076.
•The target value depends on the terminal selected in frequency reference selection A001 other
than that in A076.
When A001 is set to "01" (terminal), the setting of O/OI selection A005 is disabled.
•When analog input is selected for PID feedback and A001 is set to "01" (terminal), the PID target
value is selected depending on the A006 set value, as shown in the following table.
•To select RS485 for PID feedback, transfer data as described below.
