Thermal Overload of Output Stage / Internal Unit Error

What does 11 mean?

This fault indicates that the temperature of the inverter's output stage has exceeded its permissible limit, or a general internal unit error has occurred. Persistent thermal overload can lead to premature failure of the inverter's power electronics.

• Accumulation of dirt or dust on the heat sink, impeding cooling.
• High ambient temperature around the MOVIMOT unit.
• Restricted airflow or heat build-up around the unit due to improper installation.
• Excessive load on the drive, causing the output stage to dissipate too much heat.

Click steps to track your progress.

1. 1

   Clean the heat sink to ensure proper thermal dissipation.

2. 2

   Lower the ambient temperature around the MOVIMOT unit.

3. 3

   Ensure adequate ventilation and prevent heat build-up around the unit.

4. 4

   Reduce the load on the drive.

5. 5

   Reset the fault by switching off and then switching on the DC 24V supply voltage.

6. 6

   Reset the error via the error reset function.
