Thermal overload of the output stage or internal unit defect

¿Qué significa 11 ?

The inverter's output stage or an internal unit has reached an excessive operating temperature. This can be caused by restricted airflow to the heatsink, high ambient temperatures, inadequate ventilation leading to heat build-up, or excessive load on the drive system. Sustained overtemperature can result in permanent damage to the inverter components.

• Blocked or dirty heat sink restricting proper airflow.
• Ambient temperature exceeding the inverter's specified operating range.
• Inadequate ventilation causing heat build-up around the unit.
• Excessive mechanical or electrical load on the drive system.

1. 1

   Clean the heat sink thoroughly to ensure proper airflow and heat dissipation.

2. 2

   Measure the ambient temperature in the vicinity of the inverter and verify it is within the specified operating range.

3. 3

   Verify that all ventilation openings are clear and air circulation is adequate.

4. 4

   Reduce the load on the drive to decrease thermal stress.

5. 5

   Reset the fault by switching off the DC 24 V supply voltage to the inverter for at least 10 seconds.
