The CANWORLD CDE300 series inverter is a high-performance variable frequency drive (VFD) designed for three-phase motor control, widely used in industrial automation. Its primary functions include adjusting motor speed, improving energy efficiency, and ensuring smooth equipment operation. However, in practical applications, inverters may encounter faults due to various reasons. Among these, the ERR10 fault—indicating module overheating—is a common alarm that requires prompt attention to prevent equipment damage or downtime.

This article is based on the “CDE300 CANWORLD Three-Phase User Manual V1.10.pdf” and the provided fault screenshot. It provides an in-depth discussion of the ERR10 fault, including its meaning, potential causes, troubleshooting steps, and preventive measures. Through a clear structure and logical analysis, this article aims to offer practical guidance to help users quickly resolve module overheating issues and ensure long-term stable operation of the equipment.

Meaning of ERR10 Fault

The ERR10 fault in the CANWORLD CDE300 series inverter specifically indicates “module overheating.” The power module of the inverter, typically composed of core components such as Insulated Gate Bipolar Transistors (IGBTs), is responsible for converting the input power into the appropriate output voltage and frequency for motor operation. During operation, these components generate significant heat due to energy losses. To protect the equipment, the inverter is equipped with temperature sensors that monitor the power module’s temperature in real time. When the temperature exceeds a safe threshold, the system triggers the ERR10 fault alarm and may automatically shut down to prevent further thermal damage.

The consequences of module overheating should not be underestimated. Prolonged high temperatures can lead to IGBT aging, performance degradation, and even permanent damage to the power module. Therefore, accurately understanding the ERR10 fault and taking effective measures are crucial.

Possible Causes of ERR10 Fault

Module overheating is usually caused by a combination of factors. Based on the design features of the CDE300 series inverter, the user manual, and common issues in industrial applications, the following are the main potential causes of the ERR10 fault:

1. High Ambient Temperature
   According to the “Installation Site” section in Chapter 3 (PAGE22) of the user manual, the operating ambient temperature for the CDE300 series inverter should typically be between -10°C and 40°C. If the installation environment exceeds this range, the inverter’s cooling system may be unable to effectively reduce the module temperature, triggering the ERR10 fault.
2. Poor Ventilation
   The inverter requires adequate airflow for heat dissipation. The manual mentions the need for sufficient space around the inverter during installation (PAGE13, Section 2.5.1 “Product Installation Dimensions”). If the installation location is too confined or near other heat sources, heat accumulation may occur, affecting cooling efficiency.
3. Cooling System Failure or Blockage
   The CDE300 series inverter relies on built-in fans and heat sinks for thermal management. If the fan stops working, operates at reduced speed, or if the heat sink is clogged with dust or grease, cooling efficiency will significantly decrease. This is particularly common in industrial environments where the air may contain a high concentration of particulates.
4. Overloaded Condition
   When the load driven by the inverter exceeds its rated capacity, the power module will bear higher current and thermal stress. The manual’s Section 2.3 “CDE300 Series Inverter Models” (PAGE9) lists the rated power for each model, such as CDE300-4T7R5G/011P. If the actual load exceeds the specifications, it may lead to module overheating.
5. Wiring Issues
   Incorrect electrical installation (such as loose or poor connections) can increase resistance, generating additional heat. Section 3.2 “Electrical Installation” (PAGE25) and the “Main Contents of the Distribution Room” on PAGE30 emphasize the importance of proper wiring and grounding. Wiring errors may indirectly cause the ERR10 fault.
6. High Switching Frequency
   A higher switching frequency in IGBTs results in increased heat generation. If the switching frequency is set too high in the inverter’s parameters, it may exacerbate the thermal load on the module, leading to overheating.
7. Hardware Failure
   If all external factors are normal, the issue may lie with the power module or temperature sensor itself, such as a damaged IGBT or a malfunctioning sensor reporting false high temperatures.

Troubleshooting and Solutions for ERR10 Fault

To resolve the ERR10 fault and restore the inverter to normal operation, users can follow these step-by-step troubleshooting procedures:

1. Power Off and Cool Down the Equipment
