Description
bypass mode to inverter mode is
0–20 ms. Set this parameter
based on the output interruption
time acceptable to loads.
Cross currents occur during the
transfer between bypass mode
and inverter mode, which
impacts the system. This
parameter specifies the number
of transfers between bypass
mode and inverter mode within 1
hour, which ensures system
security.
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 maintenance page.
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 (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
