Proper wiring is critical for the safe and correct operation of the VFD. Refer to the diagrams below for connection details. Always ensure power is disconnected before making any connections.
This diagram illustrates the basic electrical connections for the VFD. It shows the input power terminals (R, S, T, E), connections for a potentiometer for speed control (10KΩ, VR+10V/5V, VI, ACM(GND)), various multi-input terminals (AI, FOR, REV, RST, SPM, SPH, SPL, DCM(COM)), RS485 communication ports, multi-output terminals (KA, FB, FA, FB, DRV, UPF, DCM), and the U.V.W output terminals for connecting to a three-phase motor. The diagram also notes that it serves as a reference, and the actual product should be taken as the standard, with the diagram subject to change without notice.
This detailed wiring diagram shows a practical setup. Input power is connected through circuit breakers to the R and S terminals of the VFD. The output power terminals U, V, and W are connected to the 3-phase motor. A ground connection is also shown. The image clearly depicts the VFD's control panel and the terminal block for connections.
