Siemens MM430 inverter can realize PID closed-loop control of pressure, flow and so on.

Three elements of PID closed loop: 1. Given 2. Feedback 3. PID controller

The PID closed loop can be realized by correctly setting the relevant parameters of these three elements. The relevant parameters are as follows:

1.P2200PID controller is enabled
2.P2253PID given value
3.P2264PID feedback value
4.P2280PID proportional gain coefficient
5.P2285PID integration time
The PID proportional gain coefficient and PID integration time should be adjusted according to the actual application. For different applications, the values ​​set by P2800.P2285 are different.
In practical applications, PID reference value and PID feedback value can be input by multiple channels. The following examples give instructions.
Example 1: Analog input 1 is PID given analog input 2 is PID feedback

The debugging steps are as follows:
1. Refer to manual 3-12, page 3-13 for quick commissioning:
2.P2200=1PID regulator enable
3.P2253=755:0 analog input 1 is given by PID
4.P2264=755:1 analog input 2 is PID feedback
5.P2280=8PID proportional gain coefficient (for reference only)
P2285=80PID integration time (for reference only)
