Description
Cross currents occur during
the transfer between bypass
mode and normal mode,
which impacts the system.
This parameter specifies the
number of transfers between
bypass mode and normal
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 running information
screen.
Specifies whether an
Inverter asynchronous
alarm can be displayed on
the LCD when the inverter

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.
