Setting up ACS 880, would like to set up parameter 31.21 to fault on supply phase loss but it is not listed

Hi
can you indicate which HW - model and size - and FW are you using on your drive?
Parameter 31.21 is not in the standard parameter list of ACS880. Where have you find 31.21 parameter?
If you give us more information, maybe we can help you better

Hi
the supply phase loss cause a under voltage on DC bus. You can try to use the parameter 30.31 for your application.
But if you have in your drive one IGBT supply unit, you can activate the parameter 31.121 - LSU supply loss - (Only visible when IGBT supply unit control activated by parameter 95.20)
The parameter 31.121 selects how the supply unit reacts when a supply phase loss is detected.
Do not forget that I have asked you your drive type/size. Not in all drive is possible to activate 95.20 parameter.
Hope this help you
