The current specification can adjust the speed through the up and down buttons on the panel, or use an external potentiometer to connect to the control terminal.
If you use single-phase 220v, please connect it to R and T. If S is empty, there is no need to connect it.
If you have 3 phase 220v then connect to RST.
The three wires of the motor are connected to U, V, and W.
Only wires can be connected between the motor and the inverter, and no switch can be installed in between.
