| Parameter | Name | Recommended Value for 0.75kW Motor | | :--- | :--- | :--- | | P0-01 | Motor control mode | 0 (V/F control) or 1 (Sensorless vector) | | P0-03 | Max output frequency | 50.00 Hz (or 60.00 Hz for North America) | | P0-04 | Upper limit frequency | 50.00 Hz | | P1-00 | Motor rated power | 0.7 kW (or 0.75 kW depending on motor plate) | | P1-01 | Motor rated voltage | 220 V | | P1-02 | Motor rated current | Find value from motor nameplate (typical: 3.5–4.2A) | | P1-03 | Motor rated frequency | 50 Hz or 60 Hz | | P1-04 | Motor rated speed | e.g., 1420 RPM (for 4-pole 50 Hz) |

| Fault Code | Description | Likely Cause & Solution (from manual) | | :--- | :--- | :--- | | | Overcurrent during acceleration | – Acceleration time too short (increase P0-06). – Motor short circuit (check U,V,W wiring). | | E.OU1 | Overvoltage during deceleration | – Deceleration time too short (increase P0-07). – Add braking resistor (manual shows TB/TA wiring for brake). | | E.LU | Low voltage | – Input voltage drops below 170V. Check L/N connections or supply stability. | | E.OH | Overheat | – Heatsink temperature >85°C. Clean fan or improve ventilation. | | E.SC | Motor short circuit | – Immediate trip. Power off, measure resistance U-V, V-W, W-U (should be equal, > few ohms). | | E. EF | External fault | – Terminal S input configured as external fault has been triggered. | invt che100-0r7g-s2 manual

| Component | Action | Period | | :--- | :--- | :--- | | Cooling fan | Listen for noise, check rotation. Replace if stuck. | 2 years | | DC bus capacitors | Measure capacitance (requires special meter). | 5 years | | Input/Output terminals | Torque to 0.8 Nm (M3.5 screws). | 1 year | | Heatsink | Clean dust with compressed air (power off!). | 6 months | The INVT CHE100-0R7G-S2 manual is not merely a document—it is the single most critical tool for ensuring safe operation, peak motor performance, and rapid fault recovery. While this guide summarizes the essential sections, always keep the official PDF within arm’s reach in your control cabinet or digital library. | Parameter | Name | Recommended Value for 0

Introduction The INVT CHE100-0R7G-S2 is a compact, high-performance variable frequency drive (VFD) designed for controlling single-phase AC motors. As part of INVT’s renowned CHE100 series, this specific model—denoted by 0R7G (0.75kW) and S2 (single-phase 220V input)—is widely used in small conveyors, fans, pumps, and industrial machinery. – Add braking resistor (manual shows TB/TA wiring
