<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 previous fault.
Displays the frequency reference at the previous fault.
Displays the output frequency at the previous fault.
Displays the output current at the previous fault.
Displays the motor speed at the previous fault.
Displays the output voltage at the previous fault.
Displays the DC bus voltage at the previous fault.
Displays the output power at the previous fault.
Displays the torque reference at the previous fault.
Displays the input terminal status at the previous fault. Displayed as in U1-10.
Displays the output status at the previous fault. Displays the same status
displayed in U1-11.
Displays the operation status of the drive at the previous fault. Displays the
same status displayed in U1-12.
Displays the cumulative operation time at the previous fault.
Displays the speed reference for the soft starter at the previous fault.
Displays the q-axis current for the motor at the previous fault.
Displays the d-axis current for the motor at the previous fault.
Displays the degree of rotor deviation when the most recent fault occurred
(same status will appear as shown in U6-10).
Displays the temperature of the heatsink when the most recent fault occurred.
Displays the first to the fourth most recent faults.
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.
Displays the cumulative operation time when the first to the fourth most
recent faults occurred.
Displays the cumulative operation time when the fifth to the tenth most recent
faults occurred.
