Description
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 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.
Description
Specifies whether to start bypass mode
when overtemperature occurs.
