LCD Display
Displays the cumulative operation time of the drive. The value
for the cumulative operation time counter can be reset in
parameter o4-01. Use parameter o4-02 to determine if the
Drv Elapsed Time
operation time should start as soon as the power is switched on
or only while the Run command is present. The maximum
number displayed is 99999, after which the value is reset to 0.
Displays the number of times the Run command is entered.
Reset the number of Run commands using parameter o4-13.
RUN Cmd Counter
This value will reset to 0 and start counting again after reaching
65535.
Displays the cumulative operation time of the cooling fan. The
default value for the fan operation time is reset in parameter
Fan Elapsed TIme
o4-03. This value will reset to 0 and start counting again after
reaching 99999.
Displays main cooling fan usage time as a percentage of its
expected performance life. Parameter o4-03 can be used to reset
Fan Life Mon
this monitor.
Replace the fan when this monitor reaches 90%.
Displays main circuit capacitor usage time as a percentage of
their expected performance life. Parameter o4-05 can be used
to reset this monitor.
Replace the capacitor when this monitor reaches 90%.
Displays the soft charge bypass relay maintenance time as a
percentage of its estimated performance life. Parameter o4-07
ChgCirc Life Mon can be used to reset this monitor.
Replace the soft charge bypass relay when this monitor reaches
90%.
Displays IGBT usage time as a percentage of the expected
performance life. Parameter o4-09 can be used to reset this
IGBT Life Mon
monitor.
Replace the IGBT when this monitor reaches 90%.
Displays the heatsink temperature.
Heatsink Temp
Lights all segments of the LED to verify that the display is

working properly.
Monitors the drive cumulative output power usage. The value
kWh Lower 4 dig
is shown as a 9-digit number displayed across two monitors
U4-10 and U4-11.
Example:
12345678.9 kWh is displayed as:
kWh Upper 5 dig
U4-10: 678.9 kWh
U4-11: 12345 MWh
Displays the highest current value that occurred during run.

U4-13 occurred.
Shows the value of the motor overload detection accumulator.
Motor OL1 Level
100% is equal to the oL1 detection level.
