6.3 Heat Dissipation
The inverter features an independent air duct design for efficient cooling of IGBT power devices. The software also includes an automatic reduction of carrier frequency based on temperature rise to prevent overheating.
7. Troubleshooting
The KC200 Series Inverter is equipped with various protection mechanisms to ensure safe operation. Understanding these can help in diagnosing and resolving issues.
7.1 Fault Alarms and Protections
- Overcurrent Suppression Protection: Real-time current monitoring limits current to prevent overcurrent.
- Overvoltage Suppression Protection: Automatically adjusts operating frequency or uses magnetic flux braking to prevent overvoltage due to high bus voltage, even without a brake resistance.
- Undervoltage Suppression Protection (Instantaneous Non-Stop): Maintains operation during instantaneous power loss.
- Wave-by-Wave Current Limiting: Limits current spikes from sudden loads or abnormal conditions to prevent overcurrent faults.
- Heat Dissipation Treatment: Software automatically reduces carrier frequency based on temperature rise to prevent overheating.
- Overvoltage, Overcurrent Fault Protection: Triggers an alarm and shutdown if these conditions exceed limits.
- Input Phase Loss: Detected based on bus voltage fluctuations; requires a certain load for detection.
- Output Phase Loss: Quickly detected before and during operation.
- Phase to Phase Short Circuit and Short Circuit to Ground Fault: Quickly detected within 10ms before operation.
- Other Faults: Inverter module overtemperature, parameter self-learning failure, current detection failure, SVC stall failure, etc.
If a fault occurs, the display will show a corresponding error code. Refer to the comprehensive user manual for specific error code definitions and detailed troubleshooting steps.
8. User Tips
- Always ensure the inverter is properly grounded to prevent electrical hazards.
- Before making any wiring changes or maintenance, disconnect all power sources and wait for the DC bus capacitors to discharge completely.
- For optimal performance, match the inverter's power rating closely to your motor's requirements.
- Utilize the parameter copy function to save and restore settings, especially when configuring multiple inverters or after a factory reset.
