Description
Displays the cumulative operation time of the cooling fan. The default value
for the fan operation time is reset in parameter o4-03. The maximum
number displayed is 65535.
Note: This monitor is only updated every 10 operating hours.
performance life. Parameter o4-03 can be used to reset this monitor.
Displays main circuit capacitor usage time 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
its estimated performance life. Parameter o4-07 can be used to reset this
monitor.
Displays IGBT usage time as a percentage of the 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 highest current value that occurred during run.
Displays the output frequency when the current value shown in U4-13
occurred.
Shows the value of the motor overload detection accumulator. 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
