Output Phase Loss
Protection Sel
Sets the function to enable and disable output phase loss detection. The drive starts
output phase loss detection when the output current decreases to less than 5% of the
drive rated current.
Note:
The drive can incorrectly start output phase loss detection in these conditions:
•
The motor rated current is very small compared to the drive rating.
•
The drive is operating a PM motor with a small load.
0 : Disabled
1 : Fault when one phase is lost
2 : Fault when two phases are lost

Heatsink Fan Off-Delay
Time
Sets the length of time that the drive will wait before it stops the cooling fan after it
cancels the Run command when
