When the inverter detects an anomaly, it protects the system by stopping output and displaying a fault code on the LED keypad. Fault Code Fault Description Potential Causes Corrective Actions Inverter Phase U/V/W Output Short Circuit
• Increase acceleration time.• Check motor and cable insulation.• Contact technical support. Overcurrent during Acceleration/Deceleration/Constant Speed
: Always install the inverter vertically to facilitate correct airflow through the fan-cooling heat sinks. I can generate a tailored for your application
The inverter must be securely grounded to prevent electric shock and reduce electromagnetic interference (EMI).
Additionally, you can use to clear all stored fault history records, which can be helpful for a fresh start after diagnosing a recurring issue.
Based on standard CHE100 manual data.
| Fault Code | Description | Suggested Action (from manual) | |---|---|---| | OC | Over-current at constant speed | Check for sudden load changes, motor winding short circuits, or incorrect acceleration time | | OU | Over-voltage | Check deceleration time (too short causing regenerative energy), or input voltage exceeding spec | | LU | Under-voltage | Check input power supply stability and voltage levels | | OH | Over-heat | Verify ambient temperature, cooling fan operation, and proper air circulation around heatsink | | OL1 | Motor overload | Reduce motor load or increase motor capacity; check current limits | | OL2 | Inverter overload | Reduce load or check for prolonged operation at overload capacity | | EF | External fault | Check peripheral device signals connected to input terminals | | CE | Communication error | Verify RS485 wiring, baud rate settings, and slave address | | P OFF | Power-off protection | Input power supply interruption |
