EURA eurui E1000 series inverter uses PID to realize the relevant parameter setting and wiring of constant pressure water supply function

EURA Ou Rui E1000 Series inverter is used PID Realize the relevant parameter setting and wiring of constant pressure water supply function

We use the measured value of the remote pressure gauge as PID Feedback value , So as to realize the function of maintaining water pressure , The remote pressure gauge can actually be regarded as a potentiometer , As the needle swings , The resistance of the potentiometer is also changing , In this way, you can give the frequency converter a 0-10V The input voltage of , So as to control the output frequency of the frequency converter .

This time, Ourui E1000 Take series frequency converter as an example ,
The parameter setting of frequency converter can be referred to as follows ：

The basic parameters ：

F111： Upper limit frequency Default ：50.0
F112： Lower limit frequency Default ：0.5
F113： Target frequency Default 50.0, Here you can set it according to your actual needs

F114： First acceleration time 15.0
F115： First deceleration time 15.0

F122： Reverse inhibit 1 It works
F131： Run display options 0 Display the current output frequency

F160： Restore the factory value 0 Do not recover 1 recovery （ The new frequency converter can be recovered , It is best to reset the parameters of the used frequency converter after it is restored to the factory ）

Operation control area ：

F200： Start command source 1 Terminal instruction
F201： Source of shutdown instruction 1 Terminal instruction
F203： Main frequency source X 9 PID Adjust the &#
