Selection
Sets operation after the drive detects an
oH
alarm.

(0, 1)
L8-07
(04B3)
Output Phase Loss
Protection Sel
Sets the function to enable and disable output phase loss detection. The drive starts
output phase loss detection and the motor coasts to stop 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:
Disable output phase loss protection.
•
The motor rated current is very small compared to the drive rating.
0 : Disable
1 : Fault when one phase is lost
2 : Fault when two phases are lost
