L8-07: Output Phase Loss Detection
Enables or disables the output phase loss detection, which is triggered when the output
current falls below 5% of the drive rated current
Note:
Output phase loss detection can mistakenly be triggered if the motor rated current is very small
compared to the drive rating. Disable this parameter in such cases.
Setting 0: Disabled
Setting 1: Fault when One Phase is Lost
An output phase loss fault (LF) is triggered when one output phase is lost. The output shuts
off and the motor coasts to stop.
Setting 2: Fault when Two Phases are Lost
An output phase loss fault (LF) is triggered when two output phases are lost. The output
shuts off and the motor coasts to stop.
■
L8-09: Output Ground Fault Detection Selection
Enables or disables the output ground fault detection.
Setting 0: Disabled
Ground faults are not detected.
Setting 1: Enabled
A ground fault (GF) is triggered when high leakage current or a ground short circuit occurs
in one or two output phases.
