Configures digital frequency storage during power-down and allows for PID or PLC frequency superposition. :

: All grounding terminals must be securely connected to the earth to prevent electrical shock.

To utilize advanced features like Vector Control, the manual guides the user through inputting motor parameters. The CVF-G3 often features an "Auto-tune" (parameter tuning) function. The manual provides a step-by-step procedure to run this:

| Error Code | Meaning | Likely Cause (per manual) | Solution | | :--- | :--- | :--- | :--- | | | Overcurrent during acceleration | Acceleration time too short (P0.08) or V/F boost too high (P3.01). | Increase P0.08. Reduce P3.01 to 2-4%. | | E.OC2 | Overcurrent during deceleration | Deceleration too short (P0.09) or regenerative load. | Increase P0.09. Add braking resistor (optional). | | E.OU1 | Overvoltage during deceleration | Motor back-feeding power to DC bus. | Extend decel time (P0.09 > 20s). Enable overvoltage stall prevention (P5.01). | | E.LU | Undervoltage | Input power dip or missing phase on R/S/T. | Check mains supply voltage. Tighten input terminals. | | E.OH | Overheat | Heatsink temperature >85°C. | Clean fan. Reduce carrier frequency (P0.12). Improve cabinet airflow. | | E.SC | Short circuit | IGBT module blown or motor winding shorted. | Disconnect motor. If error persists, drive is dead (replace). |
