Cause : The AC motor drive detects over-heating of IGBT, and over the protection level of oH1 warning.

1. Check the ambient temperature.
2. Regularly inspect the ventilation hole of the control cabinet.

3. Change the installed place if there are heating objects, such as braking
resistors, in the surroundings.

4. Install/ add cooling fan or air conditioner to lower the temperature inside the
cabinet.
