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
RUN Cmd Counter the number of Run commands using parameter o4-13. 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
Fan Life Mon expected performance life. Parameter o4-03 can be used to reset
this monitor.
Displays main circuit capacitor usage time as a percentage of their
Cap Life Mon expected performance life. Parameter o4-05 can be used to reset
this monitor.
Displays the soft charge bypass relay maintenance time as a
ChgCirc Life Mon percentage of its estimated performance life. Parameter o4-07 can
be used to reset this monitor.
Displays the heatsink temperature.
Heatsink Temp
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
kWh Lower 4 dig
number displayed across two monitor parameters, 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.
Current PeakHold
Displays the output frequency when the current value shown in
Freq@ I PeakHold
U4-13 occurred.
Shows the value of the motor overload detection accumulator.
Motor OL1 Level
100% is equal to the oL1 detection level.
Displays the source for the frequency reference as XY-nn.
X: indicates which reference is used:
0 = OFF
1 = AUTO
2 = HAND
Y-nn: indicates the reference source
0-01 = HOA keypad
