Func. Name/
Code Description
B002 Allowable under-voltage power failure time
The amount of time a power input under-voltage can occur without tripping the power failure
alarm. If under-voltage exists longer than this time, the inverter trips, even if the restart mode
is selected. If it exists less than this time retry will be attempted.
B003 Retry wait time before motor restart
Time delay after a trip condition goes away
before the inverter restarts the motor
B004 Instantaneous power failure /
under-voltage trip alarm
enable
B005 Number of restarts on power
failure / under-voltage trip
events
B006 Phase loss detection enable
B007 Restart frequency threshold
When the frequency of the motor is less than
this value, the inverter will restart at 0 Hz
B008 Retry after trip select
B009 Retry after undervoltage
select
B010 Retry count select after over-voltage or
overcurrent
B011 Retry wait time after trip

CAUTION: When a loss of phase occurs, increased ripple current will markedly reduce main
capacitor life over time. Diode bridge failure can also result. If phase loss occurs under load,
the inverter could be damaged. Please pay particular attention to the setting of function B006.
