No alarm occurs due to the abnormal temperature. In the main circuit, alarms such as heatsink overheat will be occurred.

UVT will occur when reactor is not connected. Always connect a reactor that matches the motor capacity.

It is based on the maximum value that can be set for frequency. Specifically, it is 400 Hz.

When the online auto tuning (magnetic field observer) is enabled, the monitoring accuracy is ± 10%.
