All Modes
Displays the operation status of the drive at the previous fault. Displays the same status
displayed in U1-12.
All Modes
Displays the cumulative operation time at the previous fault.
All Modes
Displays the speed reference for the soft starter at the previous fault. Displayed in the same way
as U1-16.
V/f OLV
Displays the q-axis current for the motor at the previous fault. Displayed in the same way as
U6-01.
V/f OLV
Displays the d-axis current for the motor at the previous fault. Displayed in the same way as
U6-02.
All Modes
Displays the first to the fourth most recent faults.
All Modes
Displays the fifth to the tenth most recent faults.
After ten faults have occurred in the drive, data for the oldest fault is deleted. The most recent
fault appears in U3-01, with the next most recent fault appearing in U3-02. The data is moved to
the next monitor parameter every time a fault occurs.
All Modes
Displays the cumulative operation time when the first to the fourth most recent faults occurred.
All Modes
Displays the cumulative operation time when the fifth to the tenth most recent faults occurred.
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 Up/Down command is
present. The maximum number displayed is 99999, after which the value is reset to 0.
All Modes
Displays the number of run commands that the drive has received. This counter can be reset
using parameter o4-13. The maximum number displayed is 65535, after which the value is reset
to 0.
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 in 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 in 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.
