Pro Tip: Save the PDF to your smartphone or tablet for easy access on the factory floor or inside an electrical cabinet.
Before diving into the manual, let’s decode the model number, as the manual refers to these specifications constantly:
| Code Section | Meaning | Interpretation | | :--- | :--- | :--- | | CHE100 | Product Series | INVT’s basic vector control VFD series | | 0R7 | Power Rating | 0.75 kW (approx. 1 HP) | | G | General Purpose | Suitable for constant torque loads (conveyors, mixers) | | S2 | Input Voltage | Single-phase, 200V–240V AC input (output is 3-phase) |
Critical Note from the Manual: The output of the CHE100-0R7G-S2 is three-phase 220V. It is designed to control a three-phase induction motor, not a single-phase motor. Attempting to run a single-phase motor without derating will damage the drive.
The manual dedicates an entire chapter (Chapter 7) to fault codes. Here are the most common errors for the CHE100-0R7G-S2:
| Fault Code | Description | Likely Cause & Solution (from manual) |
| :--- | :--- | :--- |
| E.OC1 | 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. |
Reset procedure: Press STOP/RESET key twice. If fault persists, cycle input power after 30 seconds.
