Description
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.
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.
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.
