The control board features screw terminals for low-voltage signals:
The Convo CVF G3 series is a high-performance, sensorless vector control inverter designed for industrial motor control applications. Key features include:
: If your site is higher than 1000 meters above sea level, you must lower the load (derate the drive). 🔌 Main Circuit Wiring
Maintain minimum clearances around the chassis to allow unimpeded airflow: Below the Drive: Sides of the Drive: 3. Power and Control Wiring Diagram
: Connect power supply to R/L1, S/L2, and T/L3.

The grounding terminal must be connected to a secure ground to prevent electrical shock or noise interference. Control Terminals:
Here is the content for a . Since this is a specific (and likely older or less common) VFD model, this content is structured as a typical user/technical manual, covering safety, specifications, wiring, parameters, troubleshooting, and daily use.
The CVF-G3 series covers a broad power range, typically ranging from small 0.4kW units to larger industrial models.
| Error Code | Name | Likely Cause (Per Manual) | Solution | | :--- | :--- | :--- | :--- | | | Overcurrent at acceleration | Short circuit, wrong motor parameters, or too fast ramp | Increase acceleration time (F2.00). Check motor insulation. | | Err.OC2 | Overcurrent at deceleration | Braking resistor missing, regenerative overvoltage | Add braking resistor or increase decel time (F2.01). | | Err.OC3 | Overcurrent at constant speed | Load shock, mechanical jam | Reduce load or check gearbox. Enable torque limit (F7.xx). | | Err.Ou1 | Overvoltage | Inverter braking too much energy | Increase decel time or install braking unit. | | Err.Ou2 | Undervoltage | Input power sag, missing phase on R,S,T | Check incoming supply voltage and wiring. | | Err.OH | Overheat | Fan failure, ambient too high ( >40°C) | Clean heatsink, replace fan. Reduce carrier frequency (F0.19). | | Err.SC | Short circuit | Motor wiring short to ground | Use a megger to test motor and cable. |
