[Setting procedure of PID control]
1. PID control select
•E
"P124: Analog input function select 2" is set to "1".
(When parameter P124 ="0", PID control will not be selected.)
2. Measured value (PV) setting
•E
"P125: Analog input signal select 2" is set to signal
specifications of detector.
•E Relationship between detector signal and measured
value (PV) is set with "P126: Bias frequency setting
2" and "P127: Gain frequency 2" .
Example: 4m£½0%, 20mA£½100%
3. Setting value (SP) setting
•E Setting signal of setting value (SP) is set with parameter
P004 (frequency setting signal).
(Note) When parameter P004 ="1" or "7", setting value
(SP) is set with parameter P111 (PID target
value).
•E Relationship between setting signal and setting value
(SP) is set with parameters P102 -104 (Bias/gain function
select, Bias frequency setting and Gain frequency setting).
Example: 0V£½0%, 5V£½100%
4. PID operation mode select
•E PID operation mode is selected with parameter P106 (PID control mode)
5. Proportional gain (Kp), integral time (Ti), derivative time (Td) and control cycle (Ts) settings
•E Parameters (Kp, Ti, Td) used in PID control are set to parameters P107~109.
* Automatic tuning function can be used to adjust parameters (Kp, Ti, Td) automatically and
change the setting value.
•E Cycle (Ts) applying PID control is set to parameter P110.
* Lower/upper frequency clamp of output frequency are set with parameters P099 and P100.
