Description
Displays main cooling fan usage time in as a percentage of
their expected performance life. Parameter o4-03 can be
used to reset this monitor.
Displays main circuit capacitor usage time in as a
percentage of their expected performance life. Parameter
o4-05 can be used to reset this monitor.
Displays the soft charge bypass relay maintenance time as
a percentage of the estimated product life. Parameter o4-07
can be used to reset this monitor.
Displays IGBT usage time as a percent of expected
performance life. Parameter o4-09 can be used to reset this
monitor.
Displays the heatsink temperature.
Lights all segments of the LED to verify that the display is
working properly.
Monitors the drive output power. The value is shown as a
9 digit number displayed across two monitor parameters,
U4-10 and U4-11.
Example:
12345678.9 kWh is displayed as:
U4-10: 678.9 kWh
U4-11: 12345 MWh
Displays the peak hold current during run.
