VEVOR VFD 4KW, Variable Frequency Drive 18.5A, CNC VFD Motor Drive Inverter Converter 220V, for Spindle Motor Speed Control (1or 3 Phase Input, 3 Phase Output)

Sí, si tiene dos cables de bajada de 120V, simplemente conecte los dos cables al RT por separado.

Yes, the center line does not need to be connected, only the two phase lines to the inverter, which makes up 240 volts single-phase power.

Hello Andy. This problem is caused by the lack of setting of current motor parameters. Here are some test methods for you. Power connection mode. If you are single-phase 220v, please connect to R and T, S is empty without connection. If you are three-phase 220v, then connect to RST. The three wires of the motor are connected to UMagneVPM W. The motor and the frequency converter can only be connected by wire, and no switch can be installed in the middle. Change your motor to a 3-phase 220-volt connection Which is  to change the interior of the motor's junction box to a triangle. Here is a set of test parameters for you. Pn32=3. Rated frequency of pn02= motor. Pn03=2. Pn04=1. Rated frequency of pn10= motor. Rated frequency of pn12= motor. After setting as above. The panel RUN starts and the panel STOP stops. Press the panel fwd/rev to switch forward and reverse. The upper and lower keys of the panel adjust speed. There are detailed menu instructions on page 8 of the manual.
