When a power supply voltage is imbalance or main circuit capacitor is weakening, the input
phase loss will be detected and a PF (Phase Loss) fault will be triggered.
The detection is disabled in the following situations.
·
The drive is decelerating
·
No Run command is entered
·
Output current is below or equal to 30% of the drive rated current
P7-01
Output Phase Loss Protection
Sets the output phase loss detection. The output phase loss will be detected when the output
current is less than 5% of the drive rated output current.
Note:
1. If the motor rated current is too small compared with the drive rating, output phase loss detection may be
mistakenly triggered. Set P7-01 to 0 (disabled) in this situation .
2. Output phase loss detection is not provided when the drive is running a PM motor with light load.
