Name
Description
Display
0: Disabled
1: Enabled (Detects if input
current open-phase, power
supply voltage imbalance
or main circuit
electrostatic capacitor
deterioration occurs.)
This fault is detected if a load
is greater than approximately
80% of the maximum motor
capacity.
0: Disabled
1: Enabled
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.
0: Disabled
1: Enabled
Set the ON/OFF control for
the cooling fan.
0: ON only when Inverter is
ON
1: ON whenever power is
ON
Set the time in seconds to
delay turning OFF the cooling
fan after the cooling fan OFF
command is received.
Set the ambient temperature.
If set to 60 °C, the Inverter
overload protection function
(OL2) will start 20% earlier.
0: OL2 characteristics at low
speeds disabled.
1: OL2 characteristics at
low speeds enabled.
0: Disable (gain = 0)
1: Enable
0: Disabled (FAN minor
fault detection)
1: Enabled (OH1 major fault
detection)
