Description
Monitors the current differences
between racks or modules. If this
parameter is set to Enable, the
Mod. Cur. Eql. Data can be
viewed on the running
information screen.
Specifies whether an Inverter
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.
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 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.

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
