What does 6 mean?

The DC bus voltage (VDC) has dropped below the 'Voltage warning low' limit. The motor continues to operate, but if the VDC remains low for 2-25 seconds, the inverter will trip with an Alarm 8 (Undervoltage). This can be caused by an insufficient supply voltage or an unstable power source.
