The CVF-G3 uses a parameter-based configuration system. Access these through the digital operator panel. Default/Common Settings Command Mode 0: Panel control; 1: Terminal control F2.13 S1 Terminal Function Default: FWD (Forward) F2.14 S2 Terminal Function Default: REV (Reverse) F2.10 Analog Output Configures the A0 terminal signal Maintenance and Troubleshooting Regular inspection helps prevent catastrophic failures.

| Parameter | Value | Explanation (from manual) | | :--- | :--- | :--- | | | 0 | 0 = Keypad command (Run/Stop from inverter keys) | | F0.01 | 0 | 0 = Keypad potentiometer for frequency setting | | F1.01 | 380V (or 220V) | Motor rated voltage (from motor nameplate) | | F1.02 | 5.0A | Motor rated current (critical for overload protection) | | F1.03 | 1420 RPM | Motor rated speed | | F2.00 | 5.0 sec | Acceleration time from 0Hz to 50Hz | | F2.01 | 5.0 sec | Deceleration time (increase if overvoltage trips) |

: Supports both panel control (green start/red stop buttons) and external terminal control.

If you see Err.OL (overload), do not simply increase the motor rated current. Instead, check parameter F6.02 (overload protection level). Setting this above the motor’s actual FLA will void the motor warranty and can cause a fire.

| Code | Fault | Possible Cause | Solution | |------|-------|----------------|----------| | OC1 | Over-current during acceleration | Short circuit, fast acceleration | Increase accel time (F0.10), check motor insulation | | OC2 | Over-current during deceleration | Fast deceleration | Increase decel time (F0.11), add braking resistor | | OC3 | Over-current at constant speed | Load shock, motor stall | Check load, increase drive capacity | | OU1 | Over-voltage during deceleration | Regenerative energy | Extend decel time, add braking unit | | OU2 | Over-voltage during acceleration | Input voltage too high | Check supply voltage | | LU | Under-voltage | Power dip, missing phase | Check input power | | OH | Overheat | Fan failure, ambient too high | Clean heatsink, replace fan | | OL1 | Motor overload | Motor overcurrent | Check load, adjust F1.00-F1.03 | | OL2 | Drive overload | Excessive current | Reduce load or upsize drive | | CE | Communication error | Wiring, baud mismatch | Check RS485 wiring, match baud rate |

Parameters are adjusted via the keypad to match your specific motor's requirements: P0.01 – P0.05
