U2: Fault Trace - YASKAWA A1000 Technical Manual

B.13 U: Monitors
<4> The display resolution depends on the ND/HD selection in parameter C6-01. This value has two decimal places (0.01 kW) if the drive is set for a
maximum applicable motor capacity up to and including 11 kW, and one decimal place (0.1 kW) if the maximum applicable motor capacity is
higher than 11 kW.

<1> The number of decimal places in the parameter value depends on the drive model and the ND/HD selection in parameter C6-01. This value has two
decimal places (0.01 A) if the drive is set for a maximum applicable motor capacity up to and including 11 kW, and one decimal place (0.1 A) if
the maximum applicable motor capacity is higher than 11 kW.
<2> When reading the value of this monitor via MEMOBUS/Modbus, a value of 8192 is equal to 100% of the drive rated output current.

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 temperature of the motor when the most recent fault occurred.
Note: This parameter is only available in models CIMR-Ao4A0930
and 4A1200.
