recovery time.
If Capacitor failure detection is
set to Enable, the 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 unit 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.
Enable or disable the light load
bypass current imbalance alarm.
If this parameter is set to Enable,
the load is light (less than 30%
load), and the load rate of a
certain rack is less than 10%, the
system will generate a bypass
current imbalance alarm and
cannot enter the ECO mode. If
this parameter is set to Enable,
the preceding detection is not
performed. Whether the bypass
current is imbalanced does not
affect the ECO bypass mode.
