(8EH) Previous Fault
<19> This value's number of decimal places depends on the drive model and the Heavy/Normal duty selection in parameter C6-01. The value will
have two decimal places (0.01 A) if the drive is set for a Maximum Applicable Motor Capacity up to 11 kW (refer to
and one decimal place (0.1 A) if the set Maximum Applicable Motor Capacity is higher than 11 kW.
<50> When reading the value of this monitor via MEMOBUS/Modbus a value of 8192 is equal to 100% of the drive rated output current.

Displays the degree of rotor deviation when the most recent fault occurred (same status will
appear as shown in U6-10).
All Modes
Displays the temperature of the heatsink when the most recent fault occurred.
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 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 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.
All Modes
Lights all segments of the LED to verify that the display is working properly.
