When the inverter detects an anomaly, it shuts down output power to protect itself and the motor, displaying a specific fault code on the LED screen. Fault Code Potential Causes Overcurrent during accel/decel
The autotuning procedure is described in the manual (page 35). Set the appropriate motor parameters (P2 group), select the keypad command channel, and initiate autotuning via the relevant function code. The inverter will run the motor at low speed (static tuning) or full speed (dynamic tuning) to measure resistance, inductance, and other parameters.
Explains danger levels (Danger, Warning, Caution) to prevent injury or equipment failure.
When a protection circuit triggers, the drive displays a fault code. Use this matrix to identify and resolve issues. Fault Matrix Cause: Acceleration too fast or short circuit at output.
: Sudden load spikes, unstable input voltage, or the VFD power rating is too small for the connected motor.
Covers 0.4kW up to 630kW, making it suitable for both small machinery and large industrial pumps.
When the INVT CHE100 detects an operational abnormality, it protects itself by tripping and displaying an error code on the keypad. Common Fault Codes and Solutions
Before wiring your drive, you must verify that the model matches your power grid and motor requirements. The CHE100 series typically spans the following power ranges: Input Voltage Power Range (kW) Output Frequency Control Mode Single-Phase 220V ±15% 0.4 kW to 2.2 kW 0.00 Hz – 400.00 Hz V/F Control & Sensorless Vector Three-Phase 380V ±15% 0.75 kW to 7.5 kW 0.00 Hz – 400.00 Hz V/F Control & Sensorless Vector Key Environmental Requirements -10°C to +40°C (derate above 40°C).
A similar model, , represents a 2.2 kW general-purpose inverter designed for a three-phase 380V power supply.
