The is essential for setting up and troubleshooting this versatile VFD. By adhering to the guidelines provided in the manual, you can ensure optimal motor performance and longevity of your machinery.

To preserve internal components and avoid premature aging, the installation site must strictly meet these requirements:

To start the VFD using an external physical switch and control speed via a external potentiometer: Set (Enables terminal control via S1/S2). Set P0.06 = 2 (Enables speed control via Analog Input AI1). potentiometer to terminals 4. Troubleshooting and Fault Code Reference

| Fault Code | Description | Possible Solution | | :--- | :--- | :--- | | | Over-current during acceleration | Check motor wiring; increase acceleration time. | | OV-1 | Over-voltage (DC Bus) | Solar input voltage too high; check PV array configuration. | | LV-1 | Under-voltage | Solar input too low (cloudy/night) or grid voltage too low. | | OH-1 | Inverter Overheat | Clean cooling fan; ensure proper ventilation. | | EF | External Fault | Check water level sensors (Dry run or Tank Full signal triggered). | | OL-1 | Motor Overload | Pump is jammed or head pressure is too high. | Invt CHE100 Inverter User Manualpdf

Enables precise speed control without the need for a speed encoder.

Keep this PDF bookmarked. It’s not a light read, but it has every answer you’ll need for the CHE100 – as long as you don’t mind hunting for them.

Output short-circuit, grounded motor windings, excessive load, or acceleration time is too short. The is essential for setting up and troubleshooting

: Must be installed in a well-ventilated area with ambient temperatures between -10°C and +40°C.

Built-in for models 0.4kW–11kW; units above 18.5kW require an external braking unit.

The is essential because it contains the exact wiring diagrams, function code tables, and fault diagnosis flowcharts tailored to your specific power rating. Set P0

Cooling fans generally require replacement every 30,000 operating hours. Smoothing DC bus capacitors typically require replacement after approximately 40,000 to 50,000 operating hours, depending on system load profiles and operating ambient temperatures.

Analog inputs (0–10V or 0/4–20mA) for external frequency references.

If you can tell me the or the error code you are seeing, I can help you find the exact troubleshooting steps from the manual.
