0: Disabled
1: Enabled (Detects if input
current open-phase, power
supply voltage imbalance
or main circuit

deterioration occurs.)
This fault is detected if a load
is greater than approximately
80% of the maximum motor
capacity.

2: Enabled
Output open-phase is detected
at less than 5% of Inverter
rated current.
When applied motor capacity
is small for Inverter capacity,
output open-phase may be
detected inadvertently or
open-phase may not be
detected. In this case, set to 0.
