Default Value Value Range
alarm
asynchronous
alarm can be
displayed on the LCD when the
inverter cannot track the bypass
frequency change. Normal power
supply is not affected no matter
whether this parameter is set to
Enable
or
Disable
.
Bus
overvoltage
recovery
Specifies whether to
automatically clear the alarm and
restart the power module when
the rectifier or inverter shuts
down due to a bus overvoltage
alarm. If
Bus overvoltage
recovery
is set to
Enable
, the
bus overvoltage alarm is
automatically cleared, and the
rectifier and inverter
automatically start when the bus
voltage recovers (less than 420
V) within
Bus overvolt.
recovery time
. When
Bus
overvoltage recovery
is set to
Disable
, the bus overvoltage
alarm cannot be automatically
cleared, and the rectifier and
inverter cannot automatically
start.
Enable
Disable, Enable
Bus overvolt.
recovery time
If
Bus overvoltage recovery
is
set to
Enable
, the bus
overvoltage alarm is
automatically cleared, and the
rectifier and inverter
automatically start when the bus
voltage recovers (less than 420
V) within
Bus overvolt.

Capacitor
failure
detection
If
Capacitor failure detection
is
set to
Enable
, the power module
(power unit) performs inverter
capacitor fault detection based on
the settings of
Capacitor failure
detection upper limit
and
Capacitor failure detection
lower limit
. If the power module
determines that the inverter
capacitor is faulty, it shuts down
the inverter to prevent the fault
from expanding.
