When AC power is lost or not stable for a short time, the frequency converter
will enter the power fault ride-through mode as long as the DC-bus voltage is
still maintained stable:
For 1P 200 VAC, DC-bus voltage is above 180 V
●
For 3P 380 VAC, DC-bus voltage above 370 V
●
The power fault ride-through operation will be decided by the selected options
as below:
1. The frequency converter output will be switched off
When the power supply resumes, the frequency converter will execute
speed capture and resume its previous operation, example for 3-Phase De-
vice actual minimum action voltage and recover voltage:
