5. Setup and Installation
5.1 Wiring Diagram and Terminals
Figure 5.1: Close-up view of the VFD's control panel and wiring terminals, showing input (RST), output (UVW), and control (24V, 10V, AI1, GND, DI1-DI5, TA, TB, TC, AO1, GND, FM, A+, B-) connections.
Proper wiring is crucial for the safe and correct operation of the VFD. Refer to the diagram above and follow these guidelines:
- Power Input (R, S, T): Connect the single-phase 220V AC power supply to the R and T terminals. The S terminal may not be used for single-phase input. Ensure proper grounding to the 'PB' or 'PE' terminal if available, or a dedicated ground terminal.
- Motor Output (U, V, W): Connect the three-phase motor leads to the U, V, and W output terminals. Ensure correct phase sequence for desired motor rotation.
- Control Terminals:
- 24V, 10V, GND: Power supply for external control components.
- AI1, AO1: Analog input/output for speed reference (e.g., potentiometer) or monitoring.
- DI1-DI5: Digital inputs for various control functions (e.g., start, stop, multi-speed).
- TA, TB, TC: Relay output terminals for status indication or external control.
- FM: Frequency meter output.
- A+, B-: RS485 communication terminals for remote control or monitoring.
- Braking Resistor: If an external braking resistor is required for fast deceleration, connect it to the appropriate terminals (refer to the full manual for specific connections, typically P+ and PB).
- Safety First: Always ensure power is disconnected before making or changing any wiring connections. Verify all connections are secure and correct before applying power.
5.2 Mounting
Mount the VFD in a clean, dry, and well-ventilated area, away from direct sunlight, excessive heat, humidity, and corrosive gases. Ensure sufficient clearance around the unit for proper heat dissipation. Use appropriate screws and mounting hardware to secure the VFD firmly to a stable surface.

8. Troubleshooting
This section provides solutions to common issues you might encounter. For more complex problems, refer to the detailed troubleshooting guide in the complete manual or contact technical support.
| Problem | Possible Cause | Solution |
|---|---|---|
| VFD does not power on. | No input power; loose power connections; internal fuse blown. | Check power supply; verify all power wiring; consult technician for fuse replacement. |
| Motor does not run. | Incorrect wiring (U,V,W); VFD in stop mode; frequency set to 0; motor fault. | Verify motor wiring; press RUN button; increase frequency setting; check motor for issues. |
| Overload error displayed. | Motor overloaded; VFD capacity too small for motor; acceleration time too short. | Reduce motor load; ensure VFD matches motor power (1.5KW max); increase acceleration time parameter. |
| Overvoltage/Undervoltage error. | Input voltage outside acceptable range; sudden load changes. | Check input power supply voltage; ensure stable power source; consider braking resistor for rapid deceleration. |
| Motor runs in wrong direction. | Incorrect motor phase sequence. | Swap any two of the U, V, W output wires to the motor (after disconnecting power). |
