1. Remote transmission pressure gauge and inverter wiring: The three terminals of the remote transmission pressure gauge are respectively connected to the inverter's +10V (power supply), GND (common ground), and X1 (multi-function terminal).
Second, you need to set the parameters of the inverter:
1, running command source = external terminal
2, frequency command channel = PID
3, P value, I value, D value
4, the upper frequency limit;
5, the lower frequency limit;
6. Target pressure; this is the basic parameter of the common inverter connected to the remote pressure gauge to achieve constant voltage control. Specifically, it needs to be extended according to the terminal condition and parameters of the inverter used.
