<F605: Output phase loss detection>
■ Function
When the phase loss on the inverter output side is detected, and after a certain period of time
passed, a trip occurs. The trip display is "EPHO".
■ Parameter setting
Title Parameter name
F605 Output phase loss
detection
■ How to select a setting value
0: Disabled
A trip does not occur. (Failure signal FL disabled)
1: At startup (only one time after power on)
After the power is turned on, output phase loss is detected at the first startup, and a trip occurs after
a certain period of time passed. (Failure signal FL enabled)
2: At every startup
At every startup, output phase loss is detected, and a trip occurs after a certain period of time
passed. (Failure signal FL enabled)
3: During run
A phase loss is detected during run, and a trip occurs after a certain period of time passed. (Failure
signal FL enabled)
4: At every startup + during run
At every startup and during run, a phase loss is detected, and a trip occurs after a certain period of
time passed. (Failure signal FL enabled)
5: Output shut off detection
In case you release between the motor and inverter for commercial power supply, restart the
operation with low-voltage by controlling impact after the connection at the output side is off and
connect it again. (Failure signal FL disabled)
