- (2) PID parameter setting sample program
Sample program
DT200: Control code (H0: Reverse operation PI-D mode)
DT201: Set temperature = 55
℃
(550
∗
0.1
℃
)
( Use the same unit as the one for the current temperature.)
DT202: Current temperature (Reading from WX1, unit: 0.1
℃
)
DT203: PID processing output value (automatically calculated)
DT204: PID output lower limit value (Normally, 0 %)
DT205: PID output upper limit value (Normally, 100.00 %)
DT206: Proportional gain
DT207: Integral time
DT208: Derivative time
These are automatically
selected in the auto-tuning
process.
Write them in the program.
DT209: Processing interval (Approx. 1 sec. in temperature
control. Use the same interval as the one for heater
PWM cycle.)
DT210: Auto-tuning progress
Note: DT211 to DT230 are used for the PID processing work
area. Therefore, do not use them for other uses.
