Chapter 15 PID Function (Built-in function)
15 - 51
- In the example, auto-tuning using PWM is not executed. Therefore, PWM output is set
as disabled.
SV: 1000(2.5V)
- It shows an example in which XBF-AD04A is set as the voltage input of 0~10V
Operation cycle: 1000
- In the example, it is set that PID control is executed every 100ms.
Proportional gain, integral time and differential time
- It should be initially set as 1,0,0 because PID auto-tuning results is used with PID
constant.
Max. MV: 4000
- Max. MV is set as 4000. If MV is 4000, XBF-DV04A outputs 10V.
DeadBand: 0
- It is set as 0 because the example does not use DeadBand function.
Differential filter setting: 0
- it is also set as 0 because the example does not use differential filter.
Min. MV: 0
- Min. MV is set as 0. If MV is 0, XBF-DV04A outputs 0V.
PWM junction, PWM output cycle
- It is not necessary to set them because the example does not use PWM output.
SV ramp, PV follow-up: 0
- It is not necessary to set SV ramp and PV follow-up because the example does not
use them.
Min. PV, Max. PV: 0
- Set them as 0 and 4000 respectively so that it could be identical with A/D input
module’s input scope.
