## VFD Control & Motor Wiring (1-Phase Input to 3-Phase Output) A practical **[VFD](https://forumelectrical.com/vfd-variable-frequency-drive-fault-codes/)** wiring configuration for a 3-phase induction motor based on the official installation guide, showing how to operate a three-phase motor from a 220V single-phase input supply. This wiring setup includes: 1. 220V single-phase input on R/L1 and S/L2 2. Forward and Reverse control using FWD/REV 3. Start and Stop push-button wiring 4. Speed control using a potentiometer connected to +10V, AVI, and ACM 5. Optional braking resistor connection through BR/BUE 6. Three-phase motor output on U, V, and W 7. Multi-function relay output RA, RB, and RC for fault indication 8. Control terminals MI1 to MI6 with DCM as the digital signal common. ![1](https://cdn.forumautomation.com/original/2X/6/67a73ca283a2c4e5508b00e7a006f437b9a15a45.jpeg) This VFD is designed for 220V single-phase input, and the correct control terminal names are MI1 to MI6, not M0 to M2. This type of VFD wiring is widely used in industrial automation where only single-phase power is available but precise speed control of a three-phase motor is required. Understanding proper VFD connections helps ensure safe installation, reliable operation, and effective troubleshooting.
