Description
All Modes
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 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.
All Modes
Displays the number of times the Run command is entered. Reset the
number of Run commands using parameter o4-13. This value will reset to
0 and start counting again after reaching 65535.
All Modes
Displays the cumulative operation time of the cooling fan. The default value
for the fan operation time is reset in parameter o4-03. This value will reset
to 0 and start counting again after reaching 99999.
All Modes
Displays main cooling fan usage time as a percentage of its expected
performance life. Parameter o4-03 can be used to reset this monitor.
All Modes
Displays main circuit capacitor usage time as a percentage of their expected
performance life. Parameter o4-05 can be used to reset this monitor.
All Modes
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.
All Modes
Displays IGBT usage time as a percentage of the expected performance
life. Parameter o4-09 can be used to reset this monitor.
All Modes
Displays the heatsink temperature.
All Modes
Lights all segments of the LED to verify that the display is working
properly.
All Modes
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
All Modes
Displays the highest current value that occurred during run.
All Modes
Displays the output frequency when the current value shown in U4-13
occurred.
All Modes
Shows the value of the motor overload detection accumulator. 100% is
equal to the oL1 detection level.
