Parameter Name Momentary power failure operation mode
Factory Setting 0000
Settings 0000 Operation stops after momentary power loss
0001 Operation continues after momentary power loss.
Speed search starts with the frequency reference value
0002 Operation continues after momentary power loss.
Speed search starts with the Minimum output frequency
This parameter determines the AC drive mode of operation after recovery from a
momentary power failure.

Parameter Name Maximum allowable power loss time
Factory Setting 2.0
Unit 0.1sec
Settings 0.3 5.0sec
If during a power failure the power loss is less than the time defined by F1-33, then the AC
drive will resume operation (set by F1-32). If the maximum allowable power loss time is
exceeded, the AC drive output power will remain off and must be reset to resume operation
(the fault indication will be set).

Parameter Name Minimum base block time
Factory Setting 0.5
Unit 0.1sec
Settings 0.3 5.0sec
When a momentary power loss is detected and the power failure is less than the time set by
F1-33, the AC drive output will resume operation after the specified period of time
determined by F1-34. This parameter should be set to a value where the residual output
voltage is nearly zero.
